Has anyone ever used this product? With shock surveys running into the hundreds of dollars I was wondering if this would allow me to get an overview of total numbers of large fish (LMB and Crappie) versus small fish (BG). I was thinking that it would also let me map the bottom of my .72 acre pond. All thoughts, opinions and conjecture welcomed. The item can be viewed here:
