High water alarm

[S/V AMITY]

   Just purchased a 9v battery powered water alarm.  Was recommended by The Boat Galley (on FB).  Alarm is loud and the water sensor buttons can be mounted remotely.  Is called The Watchdog Water Alarm and is available on Amazon for 15 bucks.  There are a couple of reviews of it on YouTube.  No moving parts on the sensor so can't get jammed.  No current draw so the 9v battery should last several seasons.
