The HELIX 5 CHIRP DI GPS G3 is similar to the HELIX 5 CHIRP GPS G3, but comes with a different transducer and has Down Imaging sonar. Evidently, since it’s one of the smaller units, it does not have the MEGA DI mode. It also does not have advanced networking features.
Along with the Down Imaging sonar, this Humminbird fish finder also has Dual Spectrum CHIRP sonar. It supports 50/83/200 kHz for it, and 455 kHz for Down Imaging. Also, this is the Humminbird part number 411670-1, so it includes the XNT 9 HW DI T transducer.
The included transducer supports only the High CHIRP range for the standard sonar. The unit offers you the possibility to select between a Narrow Mode (180-240 kHz) with a 25° beam, a Wide Mode (140-200 kHz) with a 42° beam, and a Full Mode which covers the full CHIRP range. The maximum depth capability of the standard CHIRP sonar is 1,200 ft. (365 m).
For Down Imaging, the transducer cast an oval beam @ 455 kHz with an angle of 75° and a maximum depth capability of 400 ft. (106 m).
Similar to the other HELIX units, this particular model comes pre-loaded with the Humminbird Basemap. These charts offer both coastal support and lake support. They’re pretty close to the Navionics charts. Of course, the unit also supports Navionics, SmartStrike, LakeMaster, and CoastMaster charts. Plus, it has the AutoChart Live which is a bathymetric mapping application that gives you the possibility to map your own lake with the most up-to-date contours.
The unit has a 5-inch diagonal display, color, with LED backlight. Its pixel resolution is 800 x 480. It does not have touchscreen technology or the extra shortcut buttons that the bigger units have. It has a microSD card slot for charts or sonar recordings. It comes with the standard Gimbal mount.
The unit does not have Ethernet, NMEA 2000, or wireless connectivity. It does have the COMs port, though, and is compatible with AIS units.
