Summary: Installed this on my 2004 Triumph 190 Bay boat and it works great! Graphics are easy to read and unit is very user friendly and intutitive. Nicest chartplotter / fishfinder I have ever used thus far.
Summary: Amazon price very good. I had the dealer install it for $75. As far as the device itself, the depth data on the charts are not very good. I'm down in Morehead City, NC, dealing with Core Sound, Back Sound, and Bogue Sound. The depths simply put are not very accurate. More like guidelines than actual data. The NOAA charts are more accurate. Fishfinder and GPS work well, and it's fairly simple to operate.
Summary: seems to work great, 3 weeks out... positive's-gps great, easy to install (despite other review's), fish finder/sonar is good but does not provide detailed imaging as advertised.. negative's-the mount is annoying and having to connect cable each time will be a weak spot... should have cable integrated into mount..
