Re: Airmar / Raymarine DST800 Transducer Issue
You hit the nail on the head - expectations! Those I have surveyed fall roughly into 2 camps. Those utilizing their first flapper valve feel that this unit is far superior to their experience with no flapper. Those who have the smaller diameter speed-only transducer with flapper are amazed that this design allows so much water in. Since I fall in the second camp my expectations have been challenged. I hope you got the chance to view my video. What would you think about sharing one of your thru-hull?
