Surface or flush mount chart plotter?
I have a Garmin echomap 65 which has been surface mounted as I replaced another unit so it was the easy option. Trouble is, it bounces around a lot and this effects the plugs which are not screw in. It even cuts out if I hit a real lumpy patch!
Iíve a big wide area to flush mount it but are there any downsides to this before I cut a big hole in the grp?
