Going Deeper

Side Imaging Sonar (SI)

One of the most powerful and sought after features of the Helix 7 is the Side Imaging (SI) functionality that provides 180 degree view of the structure and contours surrounding the boat. The lateral range for each side is 240 feet providing a combined 480 feet of coverage.

The variety of the side imaging functions includes zoom capability, splitscreen views, range and contour functions for differing perspectives and color options to enhance contrast and detailing. In addition, the highly popular WayPoint marker function allows anglers to tag the GPS location of notable structure for return trips.

Switchfire Sonar (Down Imaging)

SwitchFire sonar is a customizable return of the sonar picture that allows anglers to adapt the sonar presentation to their conditions.

Dual mode presentation of Max Mode and Clear presentation options allows anglers to augment the returns for better detail (Max Mode) or tune out noise in shallow conditions (Clear Mode). Both modes allow for color palette selection to be customized to user preference or to adjust for visibility conditions such as strong sunlight.

Rating and Reviews

We reviewed 98 customer reviews at the time of this article and they had awarded the Humminbird HELIX 7 Chirp SI/GPS G2 Combo a 4.2 out of a possible 5.0 stars on average.

A large number of reviewers surveyed noted the “crisp” and “sharp” display imaging with several customers noting “I can see the screen clearly even when it’s sunny” referring to the low glare from the unit.

Additionally, most users pointed to the high level of accuracy from the dual GPS capabilities noting “the GPS is amazing". 

Several users noted “there was a bit of a learning curve” with respect to the side-imaging technology. Due to the 2D presentation of a 3D image, learning how to interpret the side-imaging visualization was a topic of discussion from those surveyed. As a result of these feedback from surveyed reviewers we’ve included a tutorial on side-imaging here.

Additionally, a small number of reviewers noted the “pixelated” or distorted sonar imaging. Given the various frequencies utilized by the unit and suitable mount locations for the transducer it is possible that motor interference could impact signal quality if not properly installed

Casting opinions

Overall, customers who’ve followed the prescribed installation and usage guidelines appear to be happy with the high definition and detailed display options. Increased accuracy from the dual GPS system has also generated positive customer feedback for chart-plotting and location scouting.

Simply put this unit from Humminbird has a broad range of features for a price that has customers praising the value of the Helix 7.
