My sonar is the Humminbird HELIX 12 CHIRP MEGA SI GPS G2N. It is the brightest and best quality sonar I have ever used. The Helix models in general are better and brighter than HB's 1100 series.
I frequently teach both Humminbird and Lowrance classes, and I honestly believe that Humminbird produces a better product. Lowrance does a very poor job producing a quality user's manual and their unit's are missing a couple of features that would improve their use overall.
Please send me a PM about a private class and I will respond to all of the requests.
