Garmin's Panoptix all-seeing sonar technology can now be paired with a through-hull down transducer, the PS60. Previously, the only options included transom- or trolling-motor mounts. The PS60 offers three of Panoptix's views: LiveVü Down, RealVü 3D Down and RealVü 3D Historical. It comes with a stainless-steel stem, fairing block, and mounting hardware for a boat with a deadrise up to 25 degrees, and is equipped with an internal heading-reference sensor that constantly adjusts the sonar beams to compensate for boat motion. The PS60 costs $3,999.99.
