Yeah there was a ton of pictures in that Yahoo Group. It was extremely helpful. I will only be utilizing the SI at lower speeds as I read its optimal operating speed is about 2-7 mph anyways. I am used to idling around staring at my graph. I cant wait to get this thing out there and give it a trial run. I fish a lot of strip mine lakes around here that are soo clear that the fish hide deep during the days and also a lot of muddy river water that doesnt allow me to see anything at all! Its going to be interesting. I was immediately impressed when I turned on the unit yesterday and the GPS map had my position fixed instantaneously. My old lowrance took a while and wasnt nearly as detailed. My boat hasnt even left the driveway yet and I am already blown away at how capable this unit is.
I figured where I mounted it, it would be in more than enough water to operate correctly but high enough (and on that step) to be completely out of the water when I am on plane. The chances of it being hit or popped out of its bracket seem very slim. Lets just hope it stays put. The other transducer will handle the on-plane duties. Speaking of which....that "slow cure" epoxy takes FOREVER to finally set up.
The installation was as easy as pie. I spent more time ripping out/fixing/cleaning up some of the messes that the previous owners had left than I did actually installing my new humminbird. Man the things people do sometimes make you scratch your head... lol .. Now I just have to go outside and finish re-wiring my entire trailer....only a little more to go..
Thanks again!
