I Love microskiff.com!
Upgraded from my old Lowrance 334c igps unit. I looked and looked, touched, felt, tested and landed on the Garmin 740s. This thing is AWESOME. It has 7" ( rectangle ) wide screen and is a touchscreen model only one button ( power ). Installed it Friday night and took the boat out Saturday and Monday. Love this thing didn't know how bad I had it with the Lowrance. Sunday I came back and built a custom aluminum mount for it cuz the Ram-Mount wasn't cutting it ... too floppy. So if anyone is in the market for a new GPS/Fish Finder take a look at the 740s
