Summary: Unit stopped working after six months. Sent back to Garmin for re-build. Again stopped working. Nothing but trouble. Explore other alternatives for vessel radar as this one can not be counted on.
Summary: Bought a new unit and it worked great for awhile. Then got an error code - then it went away and it worked again. Now I got error code 6 and error code 1. Looked on the internet and see that several have had water inside the unit.
Summary: Haven't really tried the unit out yet, but was somewhat shocked at the amount of noise this radar made when turned on. Sounds like a turbine winding up. Time will tell if it otherwise does a great job.
Summary: I bought this unit just in case I get caught up in the fog and or in the pitch darkness which is rare here in Alaska in the summer months. After installation on top of a Radar white powder coated 4 and 3/4 inches tall 4 degree tilt forward base I found on some bidding site That also has a cut-out...
Summary: Had a brand new unit. Just out of warranty, barely used, stop working. Took it down, looked like small amount of water intruded the case. All screws were tight, case was tight but apparently not tight enough. Have searched around and found others with similar thing happen.
Summary: I purchased the GMR 18 HD radar to be displayed on my Garmin 4210 multifunction chartplotter. These are not toys but rather very sofisticated tools for any boat subject to fog and at night. Having the radar overlay onto my chartpotter is fantastic.
Summary: I have used this radar system for a couple of years mostly for my Coast Guard Auxiliary patrols including Search & Rescue. It has never failed me and the size is a welcome addition aboard my Parker 23 foot patrol boat. I highly recommend it.
