Waterproof Inline 12-Volt Power Switch

Wired this between my fish finder and the battery, and the plug-and-play SAE connectors clicked right in. The red LED backlight makes it easy to see whether the power's on when I'm launching at dawn, and the waterproof housing has held up through a few splashes.

No cutting or splicing at all — the SAE connectors clicked right into my existing fish finder wiring, and now I can kill the power from the seat instead of unplugging the battery every time. The waterproof switch has survived two splashy paddles without a hiccup.

The LED backlight is a nice touch — I can see at a glance whether my fish finder is still drawing power. Plugged the SAE connectors straight into my existing wiring, no cutting or splicing, and it's been bone dry after three trips.
