Whether you're planning a barbeque with friends at your favorite anchorage or a week's worth of dinners while cruising with your spouse, it's no fun to find you've underestimated the amount of propane you have onboard. GasWatch 212E eliminates that particular problem.

The electronic propane tank level indicator has an easy-to-read gas-level gauge and a remote color LCD display to let you know just how much gas remains in the tank. There's an audible low-level alarm, too, just in case you haven't been paying attention. Built-in safety features include a leak detector and an emergency flow limiter. The latter will actually restrict gas flow between 90 and 100 percent if abnormal flow is detected, potentially saving your boat from a toasty end.

Powered by a 9-volt battery, GasWatch 212E easily connects to your grill. It is available online at GasWatch or by calling (704) 814-0930.
