Not too long ago I mentioned how we bought a new Humminbird 768 Fish Finder for $200 rather than the regular price of $500, you can read the post here. We had installed the fish finder fairly easily, though we had to wait a little while to use it. We had gone to Dillon Reservoir and tried to launch the boat, but we weren't able to start the motor, you can read about that trip here.
As I mentioned in one of my last posts, we were able to get out to Green Mountain Reservoir and actually try out the fish finder. I'm not going to claim to be some kind of expert on fishing electronics. I also don't have a lot of experience with them, so the review that I am giving is based on using it for a short amount of time and based on my limited knowledge in fishing electronics.
