fish finders instructional DVD/VHS

[carl]

I did an internet search looking for a DVD on fish finders/sonar. I found one and took a chance. I can't be more pleased with what I found. If you have upgraded your electronics or are a beginer like me, you have to have this DVD. It not only explains what sonar is all about, but also goes into detail about what your LCD is displaying. If you honestly use your electronics this is for you. Five stars from me. Title: How the Pros use...Sonar. (fish finders). Order from Big Sky Enterprises. 24.95 plus 3.00 shipping.
