Garmin Echo 550c Review

Garmin Echo 550c: This is one heck of a Product from Garmin. I wasn’t going to do any more reviews on Garmin’s Products as they were to difficult to get any decent Information to give a good Review. This Garmin echo 550c seems to have so many features that researching it was a pleasure.

This was, I believe, the first Garmin made for freshwater fishing, but can be used in salt water also. Take a good look at this one that bounds with great features to help you catch the big one!
