At the end of 2016 Humminbird has launched the second generation of HELIX units. The HELIX 7 CHIRP DI G2 is one of them. Although it's not too much different from last years HELIX 7 DI, this new unit, as its name suggests features CHIRP sonar.
One of the first aspects to mention regarding this unit is its lack of GPS and other navigation functions. This is a standalone fish finder. It offers two types of sonar DualBeam Plus and Down Imaging, both CHIRP enhanced. It comes with the XNT 9 DI T transom transducer, which is also temperature capable.
