Review on 🐠 Humminbird Helix 7 Chirp MEGA DI GPS G3N CHO (Control Head Only) Fish Finder - 411070-1CHO by Terence Dardant

Good picture right out of the box when paired with an Ultrex Mega trolling motor. Be sure to follow the wiring recommendations. This product name says CHO (control head only). This is usually an option for those just looking for GPS capabilities and can get images from A) a built in trolling motor like the Ultrex. B) Using the image by the network device and its sensor. Run a minimum 12G cable directly to the battery. The picture is superb, but who doesn't want a bigger screen. Only complaint is I have to get a 9 or more to use them with the new Mega 360, they always seem to add the best features a size up than mine haha. If you have a network device or a built-in converter, this is definitely what you need. You will need an adapter cable to use the built in converter and an Ethernet cable as these are designed to connect directly to the Solix units.
