2.2 CHIRP Sonar overview 2.3 CHIRP DownVision overview Sonar interprets signals from the transducer and builds up a DownVision interprets signals from the transducer and builds detailed underwater view. The transducer sends pulses of up a detailed underwater view. The transducer sends pulses of sound waves into the water and measures the time it takes for sound waves into the water and measures the time it takes for the sound wave to travel to the bottom and back.

6.1 Dead rise angle Slope of hull Dead rise angle 25 degrees maximum The dead rise angle is the angle of the vessels hull from the centerline. 1. Calculate the dead rise angle. The dead rise angle should be measured on the outside of the hull from the location that the transducer is to be mounted using an angle finder or similar device.
6.2 Mounting the transducer in a hull 16. With a person inside the vessel, place the top half of the dead rise block over the threaded tube. with a dead rise 17. Apply a thick bead of marine grade adhesive sealant all around the edge of the top face of the top half of the cut dead When mounting the transducer in a hull that has a dead rise rise block, where it will meet the nut.
6.3 Mounting the transducer in a hull You should see the sealant protruding from the edges of the applied surfaces. without a dead rise Do NOT overtighten. Overtightening can cause damage to When mounting the transducer in a hull with a flat bottom (no the transducer and hull which may result in water leaking dead rise) follow the steps below.
6.4 Cored fiberglass hull mounting If installing in a cored fiberglass hull the transducer should be mounted in a non-cored section. Before installing in a cored section of the hull the area around the hole must be adequately strengthened to ensure it is not damaged when tightening the transducer.
