I bought a new Helix 7" Hummingbird Sonar to put on my front troll motor. I didn't realize that my HDS 9" would work on either the front or back transducer.
Anyway, its still in the box, with a new Ram mount and adapter plate.
I'd take $300.00 for all. The unit was $349.00 and the Ram was 69.00.
Remember its sonar only.
Perfect for small boats or kayaks
