User manual EAGLE TRANSDUCERS PD-WBK INSTALLATION INSTRUCTIONS

[. . . ] Moisen the suction cup and press it firmly onto the hull. The suction cup should be mounted just above the bottom edge of the hull. This allows the transducer a good chance to be in smooth water at all times. This will prevent the loss of the transducer if the suction cup comes loose. [. . . ] 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. For example, some manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fiberglass and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to the outer layer of fiberglass. Epoxy is poured into the hole and the transducer is then placed into the epoxy. After the epoxy cures, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. To choose the proper location for thru-hull mounting, anchor the boat in 60 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (you will need to turn the automatic and ASP functions off on L. C. G. units. ) Don't touch the controls once they've been set. Next, take the transducer out of the water and place it in the water in the sump of the boat. Observe the sonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity. Move the transducer around to find the best location. If the sensitivity control has to be increased greatly to compensate, then a different type of transducer should be mounted on the outside of the hull. If not, then mark the location that shot through the hull the best and follow the instructions below for a thru-hull mounting. 3 TRANSDUCER LOCATION (HIGH SPEED) TRANSDUCER LOCATION (TROLLING SPEEDS) 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. [. . . ] Afterwards, route the cable to the sonar unit. 5 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. Measure the diameter of your trolling motor and purchase a hose clamp slight larger. Water turbulence is at a minimum at this position. [. . . ]
