Yes, the Helix 7 CHIRP SI GPS is plenty big enough. The new wide-screen display features a Split-screen capability that allows you to run it in a dual graphics and text mode that puts more information at your fingertips. 

Does Humminbird helix 7 have side imaging?

It’s all in the name, and the name is long and lists all the units feature in one breath. Huuminbird calls their Flagship unit the Helix 7 CHIRP MEGA SI GPS 3.

CHIRP is Humminbird’s wide beam technology, MEGA SI, which denotes their top-end MEGA side imaging technology, extending to 150 feet around the boat. Which makes the Helix 7 one of the best side imaging fish finders. The GP3 is third-generation GPS technology. 

Control Unit

The Humminbird Helix 7 CHIRP SI GPS  control unit has a waterproof rating of IPX7. You can submerge it to a depth of one meter for thirty minutes should the worst happen. This also means it will not be damaged when exposed to splashes and rain.

The Transducer of the Hummingbird Helix 7 SI has three sonar modes:  side imaging, down imaging, and DualBeam Plus. These modes incorporate CHIRP SI technology, modulating the sonar beam over a wide frequency range to improve target separation and provide more detailed underwater information.

The sonar frequency ranges for the different CHIRP SI modes are:

Side imaging: 420KHz to 520KHz

DualBeam Plus: 175kHz to 225kHz and 75kHz to 95kHz

Down-imaging: 420kHz to 520kHz

The side imaging fish finder sonar can emit about a 240-foot beam on either side, and it helps to cover a large percentage of the water the surrounds the boat. Another lovely thing about the  Helix 7 CHIRP SI transducer is that it is fitted with a thermometer measuring the water temperature.  It comes with a transom mount and 6m cable.

Some of the other sonar features of Helix 7 CHIRP SI are selective fish ID+, sonar recording, and rewind, screen snapshot, bottom lock, real-time sonar, fish alarms, split zoom, and SwitchFire.

Humminbird Helix 7 Navigation


The sonar system’s SwitchFire function in on the Humminbird Helix 7 SI provides a real-time look below the water surface. It uses precision sonar, and the two modes of operation are Clear Mode and Max Mode. Clear Mode removes signals distorted by agitated water. Max Mode displays terrain information, fish representations, and water currents.

GPS and Navigation

The CHIRP SI GPS fish finder has GPS built-in and can receive with an accuracy of 2.5mk. Each Helix 7 SI GPS unit can be used to store about 2,500 waypoints or 45 routes with 50 waypoints each. Furthermore, the navigational feature of Helix 7 SI GPS is AutoChart Live. The 2D sonar will provide the information that AutoChart Live uses, and it helps to show the depth contours of the body of water.

The only issue with the feature is that you will need a ZeroLines card or LakeMaster Navionics in the card slot before the Helix 7 SI GPS can work.
