I have Humminbird Helix 9 and beds show up like the image above, and even better. Pretty amazing, actually. So, it's worth getting it tweaked to the right settings! Super easy to find all the bream one can want to catch! Down here, last year, they bedded May 10 to July 7 and I caught them every day I went except I think I had one bad day. And I use small plastic baits, Trout Magnet and Trout Slayer, for instance. Don't even need live bait.
