Have to replace the electronics on my 2520. I am down to either the Garmin 942XS with the 9" screen or the Simrad NSS9 evo3. I am not interested in the down vu, sidescan and all of that. I just want the absolute best bottom pic I can get for under $3k. 99% of my boating is for diving and most of that in 100+' of water on natural bottom reefs and ledges. Don't even mention Raymarine to me as that is the unit that quit ion me and an I was never overly impressed with it. I will later add a radar to my unit but other than that I just want the most simple to use but best bottom reading I can get between those 2. I know this may be like the Ford Chevy argument but want are the pros and cons of each unit?
