These units have been used a couple of times.
The Garmin next to it is my spare, that one is going for $2800, OBO. I just got this unit as a replacement from Garmin, the other one had a cosmetic blem and they sent me a complete unit.
Panoptix PS31 - Front liveVu, etc. $800 OBO. I use the PS30 more, this one would be better for bass fishermen.
