We put a Garmin 7012 at the helm
last winter. I had fears about how well the touch screen would work "in weather", etc. I used the thing all this season without a hitch. Mine is mounted at the helm, on the pedestal
, and is not protected (other than the protection from it's mounting 'pod'). I absolutely loved it. All my cruising was mid coast Maine
, but weather
was a bit of everything...the Garmin never gave me any cause for 'buyers remorse'. My reaction was more 'that is the best money
I've spontaneous on the boat for a long time". Good luck. I think you'll love it.
