I am locking for a small combined plotter/sonar device to aid diving trips to gps locations.
The plotter to take me to the co-ordinates, but once there the divers will require a good imaging depth sonar so they can actually see when we above the wreck or such.
split screen springs to mind
Had a quick look at Garmins website the GPSMAP551s seems to fit the bill
What does the panel think?
