The HELIX 5 CHIRP GPS G2 is a compact 5-inch fishfinder with CHIRP sonar, DualBeam PLUS, an internal GPS and a built-in Humminbird Basemap. It adds AutoChart Live mapping, so you can chart depth contours, bottom hardness and vegetation on the water without a map card. It suits small-boat, kayak and ice anglers who want mapping and CHIRP in one head unit. Against the G1 it adds CHIRP and AutoChart Live; against larger HELIX and Garmin units it gives up screen size, side imaging and Down Imaging. Owner feedback is mixed, with mounting and transducer issues recurring alongside praise for the sonar and mapping value.

Ratings average below three stars, and owners split between those who like the sonar and mapping and those who hit hardware and setup trouble. Complaints cluster around the mount and transducer rather than the sonar itself.
The Humminbird HELIX 5 CHIRP GPS G2 is a compact fishfinder with a color display and backlight. It uses CHIRP digital sonar to help show individual fish, bait and structure, and to reach greater depths and range. Smart Strike technology shows where fish are biting at any given moment.
The unit offers three sonar options. Dual Beam PLUS sonar combines two beams: a narrow beam for high-accuracy returns and bottom detail, and a wide beam for a larger search area. Broadband CHIRP sonar is a multi-range CHIRP that shows low, mid and high ranges one at a time or all together. SwitchFire sonar has two display modes, Clear and Max, that let you add or remove detail and account for water depth, temperature and turbulence.
An internal GPS is built in, along with the Humminbird Basemap, which shows underwater terrain and surrounding points of interest. AutoChart Live creates real-time maps of fishing spots with depth contours, bottom hardness and vegetation. The unit includes eight hours of built-in AutoChart Live recording time.
