Merc, I have had my electronics for a year now and the only thing better are the larger display ones. I have a “797 c2 SI Combo NVB” at the console, a “787 c2 Combo NVB” at the bow. The antenna is external and I also have the AS Interlink to network the two together. The image of the material on the bottom is so detailed it is like starting fishing all over again. Gump’s link above has great info on these things. You can also go to Yahoo’s message boards and type in side imaging for more info and pic’s from owners.
The naysayer’s (mostly stuck on Lowrance) have either not read the instruction book (and I mean 1” thick book) carefully or not taken the time to set it up. I spent about a total of 3-5 hours on the water just to get everything the way I wanted it. Once you have it dialed in to your liking, it is unbeatable. The detail of everything down there brush, rock beds, houses, cars, etc. is bad a**. The demo’s set up at bass pro or any where else is not set up completely. They just show a demo. Find someone who has their stuff dialed in and check out their set-up.
Fishalltime, the transducer for the side imaging can be used on the tm. However, it is not recommended by Humminbird (or anyone else) to be placed there and here is why. Let’s say you have the transducer mounted to the tm and are following the bank. If you turn the tm to the right the image has now shifted from the bank to the middle of the lake. Once you return back to your original course then the bank image will re-appear. So every time the tm direction is moved the image of the bottom will not be accurate.
Anyway hope this helps any wanting to get one of these systems. No I am not a HB rep or work at a marina.
