Review on 🎣 Humminbird HELIX 7 CHIRP MSI GPS G3 NAV Fish Finder: Advanced MEGA Side Imaging for Ultimate Fishing Accuracy by William Nunes

Helix 7 Mega DI/SI with Navionics chip included. Firstly, I love the Kolibri and Helix fish finders and have a lot of experience with them. It was this one I bought that didn't work properly. . The Navionics chip included in the kit would not boot into the device at all, making it obsolete. You cannot use the automatic chart or pre-installed charts as the zoom buttons do not work for any of the options. I bought a Lakemaster chip and it booted fine, but again its use was limited as the zoom buttons didn't work. that does not work. I have corrected the error and asked both Hummingbird and Navionics to no avail and the original seller will not issue a refund or replacement.
