The Birdtrap is used in the same manner as a permanent mount unit. The transducer may be mounted using the suction cup as shown in Figure 12 or, if you have a fiberglass boat with a single hull, the transducer may be paced in a small amount of water in the hull of the boat.
NOTE: The water must be in direct contact with the hull of the boat.
There cannot be any air between the bottom of the transducer and the hull of the boat.
The metal finger (with the yellow tip) is designed to hold the suction cup onto the boat at idle or slow speeds. DO NOT use this finger as a handle to remove the suction cup. When running at medium to high speeds you should first take the transducer out of the water because the suction cup cannot hold at these speeds.
