Any recomendations as far as reliability?

Noone will sleep while Lionheart sinks. I moved the alarm over from the
old boat. It's very simple......

There's a separate Rule float switch about 1' higher in the bilge than the
bilge pump. When it closes, it connects 12VDC to a Radio Shack alarm siren
up under the radar antenna pointed straight down the dock in her normal
position. You can probably hear it, outside, halfway across the city.
NOONE in the marina will sleep through its wailing, unless totally passed
out drunk, I suppose. It's powered off a separate direct battery fuse from
the bilge pump so that if that blows it won't disable the alarm. Pulling
the fuse or the float dropping is how you shut it up. No switches someone
could inadvertently shut off, thank you.

If you lift the float when threatened by some idiot in a big sport
fisherman bearing down on you at 20 knots, it will turn the other boat
quite nicely, too. Don't forget to warn the passengers to cover their
ears...Don't want anyone jumping overboard thinking we're going to dive
like a sub or explode...(c;

Never saw the unit you're refering to. The horn/siren monster was $25-30
at Radio Shack. We had a spare Rule float switch and fuse holder.
