Its here am sure but cant find. Most likley even know how
but get brain farts. How do you test these outside the boat?
Just to see if they power up. 6 volt? Put a fuse on power wire?
Have several of these and know can sit in the house and do
it but am kinda stumped. Or dumb in old age, not sure which.:confused:

Why would it be 6V? Just connect the power leads to a 12V DC power source, observing proper polarity. If the unit has an internal GPS antenna, the GPS function should work.

+1 ^^

Any 12v battery will work.
Do NOT hook it up Backwards.

If you put the palm of your hand flat on the bottom of the transducer you can very lightly feel the sonar as it pulses.
Point it sideways in a full bathtub and you may get it to report a 3-5 foot depth.
