Default GPS/Sounder installation

Greetings all you THT'rs......

I just purchased a Lowrance combo sounder/GPS unit and will mount on my CC.
What has been your history wiring directly to the battery with an in-line fuse Vs. to a panel/toggle switch? Pros/cons/etc...?
I have access for both, just route more wires under da' deck.


Keep on drilling holes, you will get it right or use up your duct tape quickly....... ;?

Been discussed many times here, but make sure you run both sets of wires to separate terminals on your fuse block, and to separate grounds. If you tie them together, your problems will begin almost immediately.

Some people install a switch on the "+" side of the network (GPS Antenna) power lead. The antenna stays powered up, even when the unit is off. It doesn't draw much, but COULD drain your battery over a long period of time. Of course, if your electronics are all tied into your main battery switch, then everything is off when the switch is turned off.

FWIW, I do not have a separate toggle for the GPS antenna on my LCX 111, and I've never had a battery problem.
