I am having a problem with the Raymarine
E80 chart plotter. When I use it with the Navionics
Platinum, the depths are totally out of whack. I can see the ST unit and the paper charts
coincide, but the chart plotter gives me a totally different number.
For example, around the Verrazano Bridge, where the sounder and chart indicate 80 feet, I get 15 feet in the chart plotter. I checked the units and measurements settings, and I confirmed that the plotter was set to feet. I tried the other units (meters and fathoms) and it also gives me erroneous depths.
Am I missing another setting? I am new with this equipment
, so I would really appreciate your help/input.
