HELP, I can't find my upgrade
The NL4 replaces your paddle-wheel with a GPS Receiver.
Paired to a GPS receiver, the NL4 emulates the paddle-wheel’s speed for a seamless
Integration... The GPS velocity is fed into your boat as if it were a paddle-wheel.
You’ll enjoy the reliability and accuracy inherent with proven GPS technology.
This will eliminate the inconsistent speeds, the frequent calibrations and
general headaches associated with paddle-wheels.
IT’S PLUG AND PLAY. NO CUSTOM WIRING REQUIRED: Separate the
Paddle-wheel connector from the computer, and insert the NL4 in its place.
Position the GPS receiver on your boat.
Thread its cable to the NL4 and insert... You’re done!
A second connector is provided for Lake Temperature (and Depth). Reinsert the
loose paddlewheel connector into it, and the secondary functions are preserved.
