Anyone have any feedback on this unit? I was thinking about getting an 899 bird and a minn kota I link but I really don't know how much I'll actually use the I link vs just the anchor feature so I'm thinking about just getting a terrova with ipilot instead. That lets me explore the Garmin units now. Any feedback on these echomap units? I can't find much on this particular unit. I like that it's si and di both on a single transducer for sure. Everything I read on the previous Garmin models is that they are extremely easy to use and have very very good side vu and down vu.
