Using a motion-activated sprinklers to battle them predators!

I recently got a motion-activated sprinkler against a raccoon that wants to get into my veggie-pad on a nightly basis. I posted a youtube video of the system in action at Backyardboogi.com. It's been two weeks and my garden has not had another hole or ripped out plant since then. I know these guys are clever so I'm curious to see if this system will keep him at bay longterm. Has anyone experience with these kinds of sprinklers?

Don't forget to change the batteries.

Don't forget to turn the water off before you head to the garden, or TURN IT BACK ON when you leave.

Double check your hoses and connections for leaks. Don't use a garden hose you have ANY doubts about--a busted hose can burn a well pump, or give you a $1000+ water bill, or flood a basement (yes, I know someone that each of those happened to).

Otherwise they word pretty well for coon and deer--until they get really hungry or it is already raining.
