Using an iPhone holder and a couple of cable ties gave me an extra screen on my sounder and what a great feature it was, I no longer had to display the map on the Lowrance and could set it to sonar, down and side scan only.

The set up was pretty rudimentary but now I know it works I’ll be searching for a permanent solution.AND if you look closely at the phone note that we had no network coverage and the Geo-Location function is still working!!!! (Must be logged in before losing service).

If you have been wanting the maps for your Humminbird, Garmin or other sounder or if you don’t have a combo unit, here is the solution.
