NOTE: Due to the wide variety of boat hulls, it is not always possible to obtain high speed depth readings.

NOTE: It is often necessary to make several incremental transducer adjustments before optimum high speed performance is achieved.

Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings.

5.Mark the transducer bracket location on the transom with a pencil, then pop up the bracket to reveal the mounting screws. Tighten the stainless steel mounting bracket screws to secure in place.

Hand-tighten only!

GPS RECEIVER INSTALLATION

To optimize performance of the GPS receiver, mount it in an area that has full exposure to the sky. The effective area of reception is 10° above the horizon. Different circumstances determine the mounting method appropriate for your GPS receiver.

If you have…

Then use:

An existing antenna stem with Stem Mount with Existing 1” - 14 Thread Stem standard 1" – 14 thread

Access for cable routing under	Access Under Mounting Location

location

STEM MOUNTING WITH AN EXISTING 1" - 14 THREAD STEM

Follow these steps to stem mount the GPS receiver:

NOTE: If you have an existing stem for mounting the GPS receiver, proceed directly to step 2 of the following procedure.

1.Determine the best location to mount your GPS receiver. Preplan and test the cable routing to your control head before any drilling or cutting of your boat surfaces. If you have purchased hardware to stem mount your GPS receiver, follow the instructions included with that hardware to mount the stem (antenna pole).

NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.
