I have a Hummingbird Helix 5 with GPS and DI. I feel like I am missing bottom structure. What is the best set up as far frequency and contrast and any advice to make it work better. OH and what in the world is switchfire? Thanks

Check out youtube it has a lot about what switchfire and other questions on humminbird sonars. Humminbird also has a website with a frequently asked question site about their sonars.

Remember that the 2d sonar cones are smaller in the HB DI units ... So the 2d will have less underwater coverage than the HB non-DI units ...
