Electronic Rat Blaster Repeller Kit Sure, you've seen these things advertised before. Big claims and a huge price, well we won't carry on about how you'll be able to keep Godzilla out of your garbage cans, but we will say this unit will do a nice job of keeping the neighborhood dog, cat or deer away. Here's the story, we had a problem at the boss's house keeping the deer out of the garden. The boss, being the electronic nut he is, bought one of these things and tried it. It worked pretty good so he figured to get another for protecting the shrubs, but at $150 a box, figured he could build his own cheaper. Here it is, cheaper and better! We?ve increased the power, put in a top-quality transducer (by Motorola), better frequency range and made it affordable. Build it into your own case or use our rugged, all metal matching case set.
