If the waters are rough or shallow, you can use Clear Mode to see fish through the turbulence and “noise” in the water. The Helix 7 also uses SwitchFire™ technology, which allows you to switch between two modes of viewing. The images are accurate enough that you can see not only fish but also lines and lures. It picks up more detail about what is below the surface because different objects reflect different frequencies. Humminbird uses what it refers to as “True CHIRP,” which has a wide resonant frequency that produces more accurate image separation and better images of fish arches.Įssentially, CHIRP technology puts more energy into the water because it sends longer pulses at different frequencies. This is the sonar and radar tech that the military has used since the 1950s. The MEGA™ imaging uses Compressed High-Intensity Radiated Pulse (CHIRP) technology. The kHz range on the device for all imaging allows for clear full, narrow, and wide views. The side imaging on these units ranges 100 feet on each side, and the down imaging ranges to 1500 feet.

If you are unfamiliar with the terms, side imaging gives you an underwater picture similar to what you would see if you flew over the area in an airplane and looked down into clear water.ĭown imaging gives you a picture similar to what you would see if you went scuba diving. The model features MEGA™ side imaging and MEGA™ down imaging, which are both new features to the Humminbird Helix units. The HELIX 7 CHIRP MEGA SI GPS G3N model, is the Helix 7 with the most features.

You can also plan trips, modify depth contours, and benefit from other features via the FishSmart app.The Humminbird Helix 7 Fishfinder series offers a range of options depending on the level of technology that you want on your boat.

It has wireless connectivity as well, so you can connect it to a WiFi hotspot for chart downloads, software updates, and more. Since it’s a G4N unit, it features an Ethernet port and an NMEA 2000 port. You can also save up to 2,750 waypoints in its memory, 47 routes, and 50 tracks. Thus, it can provide position updates 10 times per second. Thus, you can create your own bathymetric maps, in case the current Humminbird Basemap doesn’t cover your favorite lake. It also has the AutoChart Live feature which uses the unit’s sonar and GPS for detecting and drawing depth contours on your map.

It supports LakeMaster, CoastMaster, SmartStrike, and Navionics charts, so you can always upgrade it with a new charts card. Like all the other HELIX units, this one comes with the Humminbird Basemap. It also has a Temperature Graph function. It has A-Scope, Bottom Lock, Selective Fish ID, WhiteLine, Circular Flasher, Sonar Recording, and more.

Of course, the unit offers the full range of standard sonar functions. It casts conical beams with a coverage of 42° for the Wide Mode, and 25° for the Narrow Mode. However, the transducer only supports the High CHIRP range. The unit supports three main frequencies, these being 50 kHz, 83 kHz, and 200 kHz. It includes the XNT 9 HW T transducer which is a plastic model, featuring a transom mount, an internal temperature sensor, and 20 ft. It has two microSD card slots, and comes with a classic Gimbal mount. It’s a 7-inch unit, with a pixel matrix of 1024 x 600. However, since it’s a G4N unit, it does support radar, i-Pilot Link and has superior networking features. It also does not support MEGA Live sonar or MEGA 360 Imaging. The HELIX 7 CHIRP GPS G4N is one of the Humminbird fish finders without Side Imaging or Down Imaging.
