Really nice color depth/fishfinder, I had this mounted inside the hull of my Hobie Adventure,
with the "plumber putty dam" method, worked really well. Upgraded to Garmin 5 with GPS.
This is fishfinder only, not a GPS combo unit.They run about $150 on ebay. Will consider
swap for salmon fishing gear!
