Re: Hypothetical Radar

A radar uses very little juice on 'standby'. Once it is powered up and adjusted to the range you want, you can just put it on standby and power it up when you need/want it. This can be on a schedule where if the screen was clear, another vessel or danger could be 1, 5, 15 or 20 miles away, or every so many minutes, or any variation thereof.
Most radars take less than a minute to go from standby to full operation, as there is no warm-up time necessary. You could actually have your cold beer and your radar, too!
That's how we run ours unless we are using it for real-time navigation. It is just too distracting to have running all the time. We prefer the chartplotter page full time.
