Humminbird Helix 5 SI GPS

Humminbird HELIX 5 SI GPS


The Humminbird HELIX series brings a fresh line of fish finders at the beginning of 2015. They all feature a new layout, but the best part about these new units is their price. They all come for substantially lower prices than the HD ones in the 600 series.

This being said, the Humminbird HELIX 5 SI GPS, is the most affordable Side Imaging / Down Imaging fish finder that you can have. That’s why it currently occupies the 1st position in our classification. Although similar in features to the 698ci HD SI Combo, it has a different screen layout, with a pixel matrix of 480V x 800H, which gives much more space to the Side Imaging and Down Imaging views. This allows a better reading and interpretation of the underwater area you’re scanning. The screen is 256 Color TFT, 5-inch in diagonal, with backlight, for easy reading in the dark or in direct sunlight.

The HELIX 5 SI GPS fish finder comes with a standard Transom XNT 9 SI 180 T transducer. Its sonar technology is DualBeam Plus, with SwitchFire, Side Imaging and Down Imaging. It can be operated at 3 frequencies: 200 kHz / 20°, 83 kHz / 60° and 455 kHz for SI and DI. Its power output is 500 Watts (RMS) / 4000 Watts PTP, and has a depth capability of 1500 ft. for 2D views, and 100 ft. for Side Imaging. Does not support 360 Imaging, so if you would like the possibility of such an upgrade, you’ll have to opt for a 999ci HD SI Combo.

The navigational capabilities of this HELIX unit include Precision GPS, and the UniMap cartography pack, which covers the continental U.S. coastline, inland lakes and rivers at 30 meters per pixel resolution. It’s also Navionics Gold / HotMaps capable and Humminbird Mapping capable, so you can opt for one of these upgrades if you’d like. It can hold up to 2,500 waypoints, 45 routes and 50 tracks (20,000 points each).

Other features that you’ll get with this fish finder and chartplotter are: the Selective Fish ID+, Sonar Recording, Screen Snap Shot, Wide/Narrow Cone Split Screen, Upgradable Internal Software, Temperature Alarm, X-Press Menu System, 3D Chart View and many others.

Hummingbird Fish Finders - 698ci HD SI Combo

Humminbird 698ci HD SI Combo


A few new series of fish finders were released by Humminbird by the end of 2013, the Onix, ION and 600 series. And regarding the 600 series, it pretty much came to replace the 500 and 700 series which were discontinued.

These being said, one of the best (if not the best) Side Imaging fish finders from Humminbird at the moment, in terms of quality / price ratio, is the Humminbird 698ci HD SI Combo. What makes it so great? Let’s have a look at its features.

First of all, it has a big enough screen for both fish tracking and chartplotting, 5-inch in diagonal, with a pixel resolution of 480 x 640. Evidently, it has a brilliant 256 color TFT display, LCD backlit screen, making all the sonar returns much easier to interpret and understand.

The sonar capabilities of this unit are quite generous. As its name suggests, it has High-Definition Side Imaging and Down Imaging, the two options which take the sonar reading to a superior level, offering a crystal clear view of what’s directly under the boat, and side to side. The depth capability of the 698ci HD SI Combo is 100ft. for SI and DI, and up to 1500ft. for the down beam, traditional sonar view. The unit also features the Fish ID+ view.

This fish finder is equipped with Dual Beam Plus sonar, including SwitchFire. In other words, you will be able to scan the water under your boat in two modes: a 60° / 83 kHz view for a wider coverage, or a 20° / 200 kHz view, with a narrower, but more accurate coverage. Or, you can operate both views simultaneously, in split screen. The frequency of the sonar for SI and DI is 455 kHz with a total coverage of 180°. The power output of this unit is 500 Watts (RMS) and 4000 (PTP). The transducer of the 698ci HD SI Combo is the standard Transom XNT 9 SI 180 T.

Regarding the navigational capabilities of the Humminbird 698ci HD SI Combo, precision GPS, chartplotting and trackplotting are on the list, the unit being capable to store up to 2,500 waypoints, 45 routes and 50/20,000 tracks/points. It has built-in UniMap cartography package, and it’s also upgradable with an SD card for Navionics Gold / HotMaps, or Lakemaster. Unfortunately it does not support 360 Imaging.

In conclusion, the Humminbird 698ci HD SI Combo is number one in our top 5, because it basically has all the navigational and fish finding options required by any angler, recreational or pro, to take their fishing to a superior level, available for quite an excellent price, compared with other Hummingbird fish finders.

Hummingbird Fish Finders - 999ci High Definition Side Imaging Combo

Humminbird 999ci HD SI Combo

humminbird 999ci hd si combo fish finder

The 999ci HD SI Combo is one of the most complete fish finders from Humminbird, with an excellent price / quality ratio. However, it’s only on the 3rd place in this top 5 because it’s price still goes over $1,000. Other than that, it’s a great unit, and here’s what it can do.

The Humminbird 999ci HD SI Combo features an 8-inch diagonal screen, full color LCD, with backlight, and a pixel matrix of 800H x 480V. Its standard sonar covers HD Side Imaging, Down Imaging and Dual Beam Plus, having a standard coverage of 20° / 60° / 180°. Side Imaging and Down Imaging are reliable for depths up to 150 ft., while the standard 2D imaging, goes up to 1,500 ft. The Side Imaging covers a surface of 240 ft. on each side of the boat. Like most fish finders within the 900 series, it can support a QuadraBeam Plus sonar. Also, this unit is 360 Imaging capable.

The standard transducer of the 999ci HD SI Combo is a Transom XHS 9 HDSI 180 T. The standard power output of this unit is 500 Watts RMS / 4000 Watts PTP, but it has up to 1,000 Watts RMS / 8,000 Watts PTP capability, if equipped with a deep water transducer.

The navigational capabilities of this unit include Precision GPS antenna, and the ContourXD cartography pack, which covers over 3,000 U.S. lake maps, featuring depth contour lines of each one of them, so you’ll be able to know exactly how the bottom of your lake looks like. This unit can store up to 2,750 waypoints, 45 routes and 50 tracks (20,000 points each track). Regarding the optional upgrades and improvements that can be brought to this fishfinder, Navionics Platinum, Gold and HotMaps, as well as Lakemaster map package, NMEA2000, Radar2 and iPilotLink.

Other features that you will benefit from with the 999ci HD SI Combo are: Ethernet, Selective Fish ID+, Temperature Graph and Alarm, Sonar Recording, Split Screen Zoom and Snap Shot, Instant Image Update, Triplog, 3D Chart View and many others.

Hummingbird Fish Finders - ONIX10ci SI Combo

Humminbird ONIX10ci SI Combo

Humminbird ONIX10ci Side Imaging Combo Fish Finder


The Humminbird ONIX10ci SI Combo is one of the Humminbird models released last year. It features new TouchScreen Multi-Touch technology which, along with a very wide array of other options, places it above most other fish finder models. It is currently the most complete fish finder and navigational tool from Humminbird. The reason it occupies only the 4th position in our classification, is that its price simply doesn’t fit to just any pocket. Other than that, this fish finder and chartplotter is simply an outstanding piece of technology.

It has an outstanding range of sonar capabilities. It offers High Definition Side Imaging and Down Imaging, DualBeam Plus sonar and Digital Signal Processing, with a standard coverage of 20° (200 kHz), 60° (83kHz) for DualBeam Plus standard. Side Imaging beams can be operated at two frequencies: 455 kHz for a coverage of 86° (x2), or 800 kHz for a coverage of 55° (x2) and a much sharper image. Down Imaging can also use two frequencies: 455 kHz / 75°, or 800 kHz / 45°.

Standard mode is reliable for depths up to 1,500 ft, Side Imaging – 150 ft. and Down Imaging – 350 ft. If you opt for a deep water transducer, this unit can increase in power up to 1000 Watts (RMS), and become capable of scanning depths of 5,000 ft. Its standard power is 500 Watts (RMS) / 4,000 Watts (PTP). Also, this unit is 360 Imaging and CHIRP technology capable, but these options are not included.

This unit has a 10.4-inch diagonal screen, backlit, full color, with a pixel resolution of 1024H x 768V. The screen features Cross Touch technology and can be operated via direct touch like most smartphones, which simplifies the navigation through the menus by a lot.

In terms of GPS and navigational capabilities, the ONIX10ci SI Combo also offers a consistent palette of features. GPS Speed, and Precision GPS built in, chartplotting and trackplotting are on the list. The data storage goes up to 3,000 waypoints, 200 routes, and 50 / 20,000 tracks / points. Comes with the built in TriFuel cartography pack – which provides a database of maps from LakeMaster, Navionics and C-Map. There’s also a 3D chart view option included. However, the unit does not come with full Navionics Platinum, Navionics Gold HotMaps or Lakemaster, these being only optional. Last but not least, this unit has NMEA2000, an excellent communications standard option, used to connect marine sensors and display units within ships and boats.

Along with the capabilities of this fish finder presented here, there’s quite a bunch remaining, including: Temperature Graph and Alarm, Selective Fish ID+, Custom View, Digital Readout, Sonar Recording, Freeze Frame, Ethernet and many others.

Hummingbirds Fish Finders - ION 12

Humminbird ION 12

Hummingbird Fish Finder ION 12



At the moment the ION 12 is the most advanced navigational and fish finding tool provided by Humminbird. The only reason it’s not number one in this top 5, is that its price is quite a little bit high, and many of its features are optional, and you’ll have to pay extra for them. Anyway, let’s see what this fish finder can do.

Maybe the most important feature to be mentioned about the Humminbird ION 12 is the TouchScreen (Cross-Touch) technology, and can easily be operated like a tablet or smartphone, undrestanding commands like tapping or swiping the screen. Needless to say, this adds a lot of ease to its use. The unit comes with a huge, 12.1-inch diagonal screen, with a 1024 x 768 pixel resolution, brilliant color (TFT, 16.7 mm colors), with backlight.

When it comes to it’s sonar capabilities, it’s very important to know that the unit does not come with a sonar module and a transducer. But it can be equipped with an SM1000, SM2000, or SM3000 sonar module and various types of transducers. The ION 12 supports Side Imaging, Down Imaging and 360 Imaging, but they depend on the transducer you equip it with, along with other options such as CHIRP technology, 3D Chart View, Selective Fish ID+, SwitchFire, Real Time Sonar RTS Window. The unit has a power output of 2000 Watts (RMS) / 16000 Watts (PTP).

The ION 12 has a GPS receiver, but other GPS and navigational features, such as trackplotting, chartplotting, GPS speed and precision GPS are all optional as well. It supports all the cartography packages though, so you can equip it with a Lakemaster, Navionics Platinum+, Gold or HotMaps card, or TriFuel Cartography. Its memory can store up to 3,000 waypoints, 50 tracks (20,000 points each) and up to 200 routes, like the majority of the Hummingbird fish finders.

So, basically the Hummingbird ION 12 is just an advanced fish finder head unit, but in order to turn it into an advanced fish finding, radar and navigational tool, you will have to make quite some additions to it.

The Hummingbird Fish Finders presented here are the most complete of each series. They are all indeed elite fish finding tools. They all come with various System Network options like CannonLink, but only the 800,900, 1100, ONIX and ION series are Ethernet compatible.

Ethernet is a connectivity solution to other Humminbird units, allowing your to share waypoints, routes, tracks, GPS position and even Sonar information. However, you won’t be able to get SI Sonar information on a Humminbird unit that’s not compatible with SI.

All in all these are all top-shelf Hummingbird fish finders and which will maximize your fishing experience. They all have 1 year warranty. As far as it concerns me, I don’t think you’ll ever regret of purchasing any of the Hummingbird Fish Finders reviewed here.

Humminbird Fish Finder HELIX 7 SI GPS Review

HELIX 7 Side Imaging and GPS - from Humminbird

Humminbird HELIX 7 SI GPS

For the summer of 2015, Humminbird has launched a new line of fish finders: the HELIX 7 series. As terminology suggests, they all feature a 7-inch display, among other fish finding and navigation features. Evidently, one of the best models of the series is the SI model. Therefore, let’s see what the HELIX 7 SI GPS combo can do.

To begin with, the head unit features a 7-inch HD display, easy to read in direct sunlight or during night fishing, being LED backlit. The display is 256 TFT color, with a 480 x 800 pixel matrix. It comes with a gimbal, tilt/swivel mount, but there’s also the in-dash mounting option. The unit has NMEA 0183 port, but does not support NMEA 2000 connections. Also, it has a microSD card on the left side, for snapshots, recording sonar, and for superior maps.

In terms of sonar technologies, this unit has both Side Imaging and Down Imaging, and for standard sonar it uses DualBeam Plus. Like all fish finders from Humminbird, this HELIX model comes with the transducer that supports all the sonar technologies the unit is capable of. In other words, the box includes the XNT 9 SI 180 T, with transom mount. This transducer is capable of three frequencies: 83/200/455 kHz. Both the SI and DI use the 455 kHz frequency with different beams. Side Imaging uses two lateral beams of cca 84° each, covering 480 ft side-to-side (240 on each side). Down Imaging sonar is actually created from the side beams, the user being able to select from a narrow, medium and wide beam. Both SI and DI beams are fan-shaped, razor-thin. Needless to say, both of them offer photo-like clarity imaging. Side Imaging shows an above perspective of the bottom, and Down Imaging shows what’s under the boat.

Just as the HELIX 5 SI GPS, the standard sonar uses two conical beams, of 20° for 200 kHz, and 60° for 83 kHz. Since it’s DualBeam Plus sonar, you can opt to view the return of both beams simultaneously in split-screen, or even blended together. Also, via the SwitchFire function, you can quickly select between a view with maximum of returns, and a clear view, which focuses on fish arches.

The HELIX 7 SI GPS has several other sonar functions that you will find useful. One of them is sonar recording which allows you to scroll through the sonar feed, in order to review a spot you recently sailed over. In case you like ice fishing, the circular flasher function will surely help. And finally, selective FishID+ will help distinguishing between structure and fish, by displaying fish arches as fish icons.

The transducer supplied with this unit also has a temperature sensor built-in, which means the unit can track temperature. It does not have the graph function though.

For navigation, this Humminbird HELIX unit comes with the Precision GPS internal antenna, which uses WAAS for correction. It’s quite an accurate GPS system providing quick fixes within 2.5 m. Although the maps of this unit aren’t super, as it comes with the UniMap pack, it still provides you with the contiguous US coastline and inland lakes at 30 per pixel. The unit can work with Navionics Gold/Hotmaps, LakeMaster charts, or AutoChart. Last but not least, the Humminbird HELIX 7 SI GPS can store up to 2,500 waypoints and 45 tracks in its memory. It also has the trackplotting function being able to record your track and memorizing up to 50 tracks (20,000 points each).

All in all, this unit is pretty similar to the HELIX 5 SI GPS, only it has a bigger, brighter display, offering more screen space for split views. It’s a pretty inclusive unit, with superior sonar technologies, and a sharp GPS system. It comes for quite a decent price for a medium-sized unit, being worth each and every penny.

Humminbird Fish Finder HELIX 7 GPS Review

HELIX 7 GPS combo

Humminbird HELIX 7 GPS

The HELIX 7 GPS unit, newly released in the summer of 2015, is pretty similar with the HELIX 5 GPS in terms of features and functions. Also, the unit itself is basically the same as the HELIX 7 SI GPS, only it’s not capable of Side Imaging or Down Imaging. But nonetheless, it’s a great unit to have on the water, a unit that packs a considerable amount of useful functions.

So, to begin with, this unit is equipped with a powerful internal GPS antenna, the Humminbird’s Precision GPS, with 5 updates per second and highly accurate position capabilities, typically within 4.5 meters. The GPS system of this HELIX 7 unit uses WAAS, EGNOS and MSAS information, in order to provide the most accurate results. The speed of your boat is also measured via the GPS system.

In terms of charts, the unit comes with the UniMap charts pack built-in. Although this maps software is pretty basic, it still does cover the continental U.S. coastline, inland lakes and rivers at 30 m / pixel. The charts are pretty accurate, however they do not offer much detail. However, the unit can always be upgraded with a Navionics Gold/HotMaps or LakeMaster charts chip. This unit does support however a 3D view for improved situational awareness. The point of view in 3D mode is situated above and behind the boat. Two other useful functions to be mentioned here, are the Drift Alarm and Off-Course Alarm.

Last but not least, in terms of navigation, this unit can store up to 2,500 waypoints in its memory, along with 45 routes and 50 trails (20,000 points each). These can always be copyed on a SD card, for backup.

When it comes to its sonar capabilities, this unit is pretty basic, and does not support DI or SI technology. But due to this fact, this unit is considerably cheaper than the SI or DI models. Like all Humminbird units, the HELIX 7 GPS comes with the XNT 9 20 T transducer, which is capable of two frequencies: 200 kHz / 20° and 83 kHz / 60°. It also has a temperature probe built-in, therefore the unit is temperature-capable. Its depth capability can reach 1500 ft.

Since the Humminbird HELIX 7 GPS uses DualBeam Plus sonar, it can display the returns from both beams simultaneously. They can be viewed either in split screen, separately or even blended together. Like most other HELIX units, this one also has the FishID+ function, the flasher function for ice fishing, and is capable of sonar recording. However, in order to be able to record your sonar feed, the unit requires a blank microSD card. It cannot save the recorded sonar in its memory.

The display of this unit is 7″ in diagonal. It’s also HD and LED backlit, providing bright color imaging, easy to read in direct sunlight. The unit is IPX7 waterproof, which means it can survive incidental water exposure. It’s not recommended its complete immersion though, especially in saltwater. Since it has upgradable software, evidently it has a microSD card slot. It also has a NMEA 0183 port. Finally, the box includes the gimbal, tilt and swivel mount type.

Humminbird Fish Finder PiranhaMax 197c DI Review

PiranhaMax 197c DI

PiranhaMax 197c DI

If you’re looking for the cheapest color fish finder with Down Imaging technology, the PiranhaMax 197c DI from Humminbird, IS IT! Believe it or not, this small unit excels in performance, and is one of the best choices that you can make in terms of fish finders for a small boat or kayak.

The unit has a small screen, 3.5-inch in diagonal, with a pixel resolution of 320V X 240H, full color and backlit. It comes with two types of sonar: Dual Beam and Down Imaging. The Dual Beam sonar can operate at two frequencies: 200 kHz, with a beam of 28°, and 455 kHz with a narrower, 16° beam, for more accurate results. The Down Imaging sonar only has one frequency: 455 kHz, and its coverage is 74°.

Even though it’s a small unit, it has a depth capability of 320 feet for Down Imaging, and 600 ft. for broadband Dual Beam. This is more than enough for fishing on canals, lakes and rivers, or in general, on in-land waters.

The unit comes with the Down Imaging transducer, XNT 9 DI T, which is transom type. In case you would like a through hull one, or a transducer for trolling, you can ask for a free replacement, though. The standard transducer also has temperature sensor built in. However, the unit does not support temperature alarm or temperature graph, but it does indicate water temperature.

There is no split screen function. You can only observe one sonar return at the time. But since it has Down Imaging, you will probably be using that all the time, since it’s capable of detecting much more fish than broadband sonar. The unit also has the Selective FishID+ function, which uses a different type of sonar processing, indicating fish with a fish symbol, if the sonar return meets a specific range of requirements.

The PiranhaMax 197c DI does not have any navigational features. In case you would like a more affordable fish finder with GPS and mapping, the HELIX 5 DI GPS might be a better choice for you.

Humminbird Fish Finder ONIX10ci NT SI Combo

Humminbird ONIX10ci Side Imaging GPS Combo

Humminbird ONIX10ci SI NT Combo

The ONIX fish finder series from Humminbird offers quite several model that are pretty much all-inclusive. Some of them come with cross-touch technology, other are non-tactile, commands being inserted exclusively via the unit’s keypad. The ONIX10ci NT SI Combo is one of them.

Just like the crosstouch, ONIX10ci SI Combo, this unit includes pretty much all the features that you would expect from a top-class fish finder and chartplotter. First of all, it features quite a wide screen, measuring 10.4″ in diagonal, with a pixel matrix of 1024H x 768V, full TFT color, and with LED backlight. The unit has two SD card slots, great feature in case you need to use at least two cards, for mapping or sonar recording. Needless to say, like all the other ONIX models, the NT SI one comes with NMEA2000 and 0183 connections. The unit features a gimbal, standard mount, but the in-dash mount option is also available.

The unit comes with a standard XT 14 20 HDSI T transom transducer. This transducer incorporates a temperature probe, rendering the unit capable to track water temperature. Also, when it comes to temperature measuring, this unit has the Temperature Graph function, which can help by a lot in observing the water temperature variances from a spot to another.

When it comes to sonar capabilities, this unit is clearly at the top. It has HD Side Imaging, HD Down Imaging, and Digital Signal Processing, and comes with the transducer to back them up. For standard sonar, DualBeam Plus with Switchfire is also included. The Side Imaging extends up to 240ft. on each side, offering an 180° side-to-side view for the underwater environment. This is completed by the Down Imaging, which scans what’s directly under the boat.

The DualBeam Plus sonar can be operated at 200 / 83 kHz, with a coverage of 20° and respectively 60°. For DI and SI, there’s also dual frequency, they can be operated at 455 / 800 kHz with a coverage of 75° / 45° for DI, and 86° / 55° for SI. This unit is also XD ready, meaning that it can operate with a 50 kHz transducer, for higher depths. It’s also CHIRP ready, being able to use CHIRP technology sonar, for superior target separation. However, this requires the additional purchase of a CHIRP Ethernet sonar module.

When it comes to depth capabilities, with the standard transducer this unit can scan depths up to 150′ in Side Imaging, 350′ in Down Imaging and 1500′ in standard mode. Of course, with an XtremeDepth (50 kHz) transducer, and an SM3000 CHIRP sonar module, this unit can reach an 1000 watts RMS power output, and can be used at depths up to 10,000′.

Other sonar features include Switchfire, DSP, Selective FishID+ and sonar recording. Switchfire offers the possibility to filter noise quicky, between maximum sonar information, and an image completely clear of noise. This helps quite a bit with distinguishing between targets of various nature. On the other hand, this unit has Digital Signal Processing, meaning that it’s a bit smarter than its predecessors, being able to distinguish between noise, structure and fish, in order to filter the screen better, in order to provide a clearer view. Selective FishID+ is a more intuitive sonar feature. It simply gives fish icons (of various sizes and colors), to sonar returns interpreted as fish by the unit. And finally, the sonar recording feature gives you the possibility to save sonar on a blank SD card, to show your friends, use it with the Chart View, or simply to upload online.

An important aspect to be mentioned regarding the sonar possibilities of this unit, is its compatibility with 360 Imaging. However, this requires the additional purchase of a 360 Imaging transducer.

In terms of navigation features, the ONIX10ci NT SI Combo also offers quite a range of features. To begin with, it offers the best quality Precision GPS. The unit includes the TriFuel chart pack, combining elements from Navionics, C-Map and Humminbird charts. On top of that, it’s compatible with Navionics Platinum+, Gold and HotMaps, and also with C-Map 4D and Humminbird Mapping. It also has a 3D chart view. Evidently, like most advanced Humminbird units, this particular one has routes, tracks and waypoints functions. Its internal memory can store up to 5000 waypoints, 50 tracks (20000 points each) and 200 routes.

Last but not least, the Humminbird Onix10ci NT SI Combo supports i-Pilot Link, HD Radar, and of course, it has upgradable internal software.

Humminbird Fish Finder HELIX 7 DI Review



In case you don’t want to spend extra on a unit that also has GPS, but you happen to be interested in a medium-sized unit, with Down Imaging, the HELIX 7 DI is exactly the model you’ve been looking for. It has pretty much the same features as the HELIX 7 DI GPS, only without the GPS, and a few other functions. Evidently, it also costs cca $80 less than the aforementioned unit. Anyway, let’s see what this unit can do for you.

First of all, as its name suggests, it’s a unit that has Down Imaging. And the Down Imaging provided by this unit is actually a dedicated one, being able to support 455/800 kHz. The sonar on the HELIX 7 SI GPS for example, can only support 455 kHz, and its DI beam is made from the side beams. This being said, the Down Imaging sonar provided by this unit, just as in the GPS model, offers crystal clear imaging, with photo-like clarity, excellent for determining the shape of structure and bottom. Down Imaging can operate in two, fan-shaped, thin beams with a side-to-side angle of 75° for 445kHz and 45° for 800 kHz.

The unit also features DualBeam Plus sonar, which means the 2D, traditional sonar mode also can operate at two frequencies: 200 kHz, with a beam of 28°, and 455 kHz with a narrow beam of 16°. The 2D sonar beams are conical though, not razor thin, fan-shaped like the DI beams. The 2D views can be observed in split-screen simultaneously, or even blended together.

The unit’s depth capability is 350 ft for DI, and 600 ft for 2D.

In terms of sonar, this unit also offers several other related and useful functions. Some of them are SwitchFire, Split-Zoom, Fish ID+ and Bottom Lock.

Like most Humminbird units, this one also includes the transducer that supports all the mentioned frequencies. It’s actually the XNT 9 DI T, with a transom mount. The transducer also has a built-in temperature sensor. The unit does not offer the Temperature Graph function though.

When it comes to the control unit features and functions, to begin with, it has a 7-inch display, with an 800 x 480 pixel matrix and 16:9 display. Since it’s a HELIX unit, it has 2XRAM more than previous other units, such as the ones in the 600 series. This means faster refresh. Evidently, it has has a TFT 256 color display, with LED backlight.

Its water rating it’s IPX7, which means it can withstand incidental water exposure.

The HELIX 7 DI comes with a gimbal, tilt and swivel mount. It has a NMEA 0183 port, but does not feature Sonar Recording, not has an SD card slots. And just to be clear, it does not support any type of GPS.
