PiranhaMax 150

The Hummingbird Fish Finder PiranhaMax 150, like all the models in the PiranhaMax series, is a small and basic fish and depth finder, design for simple fishfinding. Doesn’t have too many features, but it’s also one of the cheapest Hummingbird fish finders.

Ok, so let’s have a look at what it can do for you.

The Hummingbird Fish Finder PiranhaMax 150 doesn’t have a full color, flashy screen. Its screen is 4-inch diagonal wide, with 160 x 128 pixel resolution, and quite a basic 4 level grayscale (monochrome) display. However you can be sure that it will display the bottom correctly, pin point the fish under your boat with accuracy and also measure depth and the water temperature.

Like most fish finders from Humminbird, this unit is also equipped with the Fish ID+ mode, and when this is on, you can set the alarm to sound when it detects fish. This unit can easily distinguish between fish and other objects floating between waters or on the bottom. Each fish will be displayed on the screen along with indicators showing the fish size and the depth they’re located at.

Since it’s a basic fish finder, it’s only equipped with a single beam transducer, which operates at 200 kHz, covering a 20° area under the boat. Due to this fact, it might have a lower chance to detect the fish closer to the surface or to the transducer, but it will surely show the fish between waters and on the bottom. It’s reliable for depths of 600 feet.

All in all, this is an affordable Hummingbird fish finder, quite small and basic when it comes to the amount of features, but highly functional when it comes to locating fish.

365i Combo

The Hummingbird Fish Finder 365i Combo although isn’t one of the big Humminbird units, and doesn’t have a color screen, it does have quite reliable fish finding features, as long as GPS and chartplotting possibilities. As a recreational angler or boatman it’s not a bad tool to have on your boat.

Although the 365i Combo has a black and withe screen, with a 16 level grayscale display, 320V x 240H pixel resolution, its screen is slightly bigger than the one featured by the superior models in the Humminbird 300 series. The Hummingbird 365i Combo has a 4-inch diagonal screen.

It’s endowed with a DualBeam sonar, reliable for depths up to 1000 feet. Even without color returns or without Side Imaging or Down Imaging technology this unit will help you locate the big ones that will make your fishing trip unique.

It’s GPS and chartplotting capabilities include a 50 channel GPS which ensures a quick lock and will help you to quickly determine your position. Its chartplotting and trackplotting features allow you to create a well-determined fishing itinerary. The memory card of the Hummingbird Fish Finder 365i Combo can store up to 2,000 waypoints, 50 routes and 50 (20,000 points each) tracks. This Humminbird unit also has the UniMap package.

Just as for any other Hummingbird Fish Finders, this model comes with a one year warranty.

581i Combo

This is one of the best fish finders from Humminbird with monochromatic display. Apart from that it has quite a multitude of features which can make it quite a reliable unit.

The Hummingbird Fish Finder 581i Combo is endowed with a high-resolution 16 lvl grayscale display, 5-inch wide, 640 x 320 pixel resolution. Since this unit has a FTSN LCD display, it requires less power to operate and it’s obviously cheaper.

It’s equipped with DualBeam sonar, 200kHz / 20° and 83 kHz / 60°, with a reliability down to 800 ft depths. Has a 2000 Watts PtP power output. Even if it’s not a SI Hummingbird Fish Finder and also lacks the DI technology, the normal sonar still does its job, allowing you to see what passes beneath the boat, identifying the shape of the bottom, measuring depth and locating the fish you’re looking for.

For a black-and-white fish finding device this unit has plenty of GPS features, which needless to say, increase its utility. The 581i Combo is Navionics compatible, has the UniMap built-in cartography system, which covers the U.S. coastal line and most of the in-land lakes and rivers, with a 30 meter / pixel resolution. It also has a 50 channels Internal GPS, making it a nice and reliable navigational unit.

As far as it concerns the Hummingbird 581i Combo memory, it has the same card as the Best Hummingbird Fish Finders. You can write in its memory up to 3,000 waypoints, 50 tracks (20,000 points each) and 50 routes.

Humminbird 728

Although it doesn’t have a flashy full color HD screen, the black and white 5″, 16 level greyscale, 640V x 320H display featured by the Hummingbird Fish Finder 728 is still not a bad  for the recreational fisherman. Once you get used to it, it will become as reliable as a full color one. And the fish, structures or trees found on the bottom can be distinguished quite clearly on this unit’s screen.

Although a black and white, cheaper unit, this Hummingbird fish finder still has the DualBeam Plus sonar with depth penetration up to 1500 ft, allowing you to use a 20° precision beam for more accurate returns and a 60° one for a wider coverage of the bottom floor, for fish and bait fish. Has a 4000 watts PTP power output.

It’s GPS capable with the option of 50 channel GPS and trackplotting. Its memory can store up to 750 waypoints and 10 tracks (2,000 points each).

If your aim isn’t extremely clear images of the lake or sea floor, and you’re not looking for a super-color display, the Hummingbird Fish Finder 728 is not a bad choice for the price. Since you will be able to determine whether or not there are fish in the waters under you, you will certainly improve your fishing results. Like all Hummingbird depth finders it’s quite a reliable unit.
