Humminbird411390-1 MEGA 360 Imaging Universal Fish Finder Transducer

I've got the down/side scan and it's amazing. But with the Mega 360 imaging by Humminbird my Helix 12 can see whats under the boat in a 360deg field of view while sitting still. Cat fishermen you have to get this item! I can keep up with the aquatic activity as it happens. Love this!!!!
