Humminbird 718 Fishfinder Review

The Humminbird 718 Fishfinder was my first fish finder, because the time I had begun fishing I wasn’t able to spend for an expensive fish finder. On the other hand, I was approximately satisfied for its service. Although I couldn’t use it in the ocean, because it wasn’t able to send out its tracking system under 1000 ft and at the same time it has worked better in fresh water. So most of the times, I used it for inshore like fishing in the deepest lake or river while the scanning ability of it under your boat wasn’t bad.
