It can reach depths up to 600 ft (183 m) when scanning with the 2D sonar, and up to 350 ft (106 m) via Down Imaging. This unit doesn’t have extreme depth capabilities with the supplied transducer. For DI, the transducer uses thin beams fore to aft, but wider side-to-side. Also, since the 2D sonar is “DualBeam Plus”, it means that the unit can use both 2D frequency beams simultaneously, and you can view the returns from both of them in split screen. The transducer uses conical beams for DualBeam Plus, 16° and 28° wide. This CHIRP modulation results in a crisper imaging, less clutter on-screen, and a superior target separation. With this transducer, the system can use three main frequency intervals: 175-225 kHz / 420-520 kHz for DualBeam plus, and 420-520 kHz / 790-850 kHz for Down Imaging. It comes with the XNT 9 DI T transom transducer, which is also temperature capable.
#HELIX 7 HUMMINBIRD PLUS#
It offers two types of sonar DualBeam Plus and Down Imaging, both CHIRP enhanced. One of the first aspects to mention regarding this unit is its lack of GPS and other navigation functions. Although it’s not too much different from last years HELIX 7 DI, this new unit, as its name suggests features CHIRP sonar.

At the end of 2016 Humminbird has launched the second generation of HELIX units.
