I purchased a product from Boateye 360 for my 23' center console and it works great. I believe it is a commercial security camera encased in a stainless steel housing. Call and ask for Dru, the owner, as he is informative and helpful. I have it connected to my 12" Garmin. Cost was a little over $1,000.00. I fish out of Oregon Inlet and Chesapeake Bay, so I believe that is two good reference points. he has his screen , as well if you don't want to use yours.I believe it would be equally good around ports along the waterway. Elizabeth river is pretty well lighted, but the screen picks up day-markers and crab-pots, along with lumber. We have had no issues for the year we have operated it. I will be purchasing another for my 41 project when completed. needs some light, as I believe you would expect and misty mornings leaving out is hazy. I enjoy the added feature, but as others do, before all this, I would throw towel over gauges and cut machines off when running familiar territory. Also would slow down, saw long legged seagulls in Hatteras one time, and have avoided them so far ever sense!
