Technology
Side Imaging and DualBeam PLUS Sonar
 Side Imaging Sonar technology delivers picture-like views of the bottom with unequalled detail. Spot fish, bait fish, structure and see its orientation on the bottom with extreme clarity. View rising and falling bottom controus and hardness changes below and to the left and right simultaneously. An all-encompassing 180º beam pattern covers 480 feet of bottom at once, down to 150 feet deep.
 DualBeam PLUS sonar has a narrowly focused center beam, surrounded by a second beam of 60º, expanding your coverage to an area equal to your depth - in 20 feet of water the wider beam covers an area 20 feet wide. The first beam is focused on the bottom, to show you structure, weeds and cover. The second beam is hunting for fish in the wide coverage area. You can use the beams independently, yet working together they give you a clearer picture of what's going on underneath the boat.
