PT-W PD-N and PD-WBK PD-W and PD-WBK PT-W, PD-W, PD-WBK, PD-N and PD-NBK TRANSDUCERS INSTALLATION MANUAL
NOTICE When the transducer is mounted on the outside of the hull, periodically wash the transducer’s face with soap and water to remove any oil film that may collect. Oil and dirt on the face will reduce the sensitivity or may even prevent operation. Copyright © 1995, 1996 Lowrance Electronics, Inc. All rights reserved.
PT-W INSTALLATION INSTRUCTIONS ONLY The PT-W is a wide cone angle (20 degree) transducer designed to be used with portable sonar units. Assemble the transducer and bracket as shown below. Press the rubber grommet into the hole in the top of the bracket. Tie one end of the lanyard through this hole. To use the PT-W, choose an area on the transom that is free from air bubbles when the boat is moving.
PD-W & PD-N INSTALLATION INSTRUCTIONS The PD-W and PD-WBK are wide cone angle (20 degree) transducers and can be mounted to shoot through the hull, or, with an automotive hose clamp, attached to a trolling motor. The PD-N and PD-NBK narrow cone angle (8 degree) transducers are shoot-thru-hull mount only. PD-W PD-WBK Read this manual carefully before attempting the installation.
SHOOT-THRU-HULL The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood, or foam) between layers of fiberglass if the material is removed from the chosen area.
TRANSDUCER LOCATION (TROLLING SPEEDS) TRANSDUCER LOCATION (HIGH SPEED) Shoot-thru-hull Installation DEADRISE LESS THAN TEN DEGREES 1. Dry the chosen area thoroughly, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding. 2. Make certain the area is clean, dry, and free of oil or grease.
EPOXY RTV DAM HULL 3. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, as it will cause bubbles to form in the epoxy. Apply a small amount on the entire face of the transducer, then pour 1/16" level into the area contained by the dam. Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face.
CABLE TIE CABLE TIE TRANSDUCER TRANSDUCER Trolling Motor Mount - PD-W Only The top of the transducer is curved to fit the contour of the motor on electric trolling motors. Attach it using a automotive hose clamp available at any auto parts store. 1. Measure the diameter of your trolling motor and purchase a hose clamp slight larger. 2. Determine the mounting location. It should be ahead of the skeg. Water turbulence is at a minimum at this position.
