Been using Garmins for the last few years. Currently have EchoMap 53DV and 43DV on my Triton and a 301DV on my Coleman Crawdad. I have several buddies that run Garmin as well. Great screens, good mapping, and Down Vu is exceptional. The best parts are that they are so easy to use and the quick disconnect on the newer models is awesome. I doubt you will be disappointed.
