TRC3A Wireless Seismic intrusion detector

12/3/12 YEP, IT SOLD WITHIN MINUTES AGAIN FOLKS!!! UNAVAILABLE FOR 10 YEARS! MOVE QUICK ON THIS!!!! Military issue TRC3A Wireless seismic intrusion detectors offer the BEST edge for perimeter protection. Seismic probes detect minute earth vibrations and detect a person walking, a vehicle driving by or even LOW FLYING aircraft within a 20-30 yard circumference around each probe. Each probe also has it's own sensitivity setting, you might want one probe more (or less) sensitive than the others. The detection is sent via the attached transmitter to the receiver. THE INTRUDER NEVER KNOWS HE IS DETECTED UNTIL IT'S TOO LATE!!!! Unlike trip flares and dogs, the intruder HAS NO IDEA HE'S BEEN "MADE" and will continue in towards your ambush.... Each probe runs off of (2) 9 volt batteries as well as the receiver. We sold these sets for 10 years but back in 2002-03 they disappeared from the scene and are VERY RARELY found. THIS set is used, nice and tested. 3 probes work flawlessly. Bag and all equipment looks nice as well. "new" sets have not been available in years, understand their might be minor cosmetic problems with these units, but we TEST and verify their use before shipping! This set includes 3 probes and the carry bag. Any commercial receiver in this frequency range will work. These ALWAYS SELL FAST. Consider what you are getting here- *3 guards that are always out there *3 guards you don't have to feed. *3 guards that will alert you up to 1/2 MILE away from where you have the receiver! *3 guards that will NOT give your position away like a dog will. *3 guards that are easy to carry and will last 2-3 weeks off a set of batteries. PERFECT for the small group or family that will be 'short' of guards for watch duty. All I can add is- BUY NOW OR CRY LATER. We haven't seen these regularly in SIX YEARS, ACT ACCORDINGLY. First come first served! $20. ship per set. They ALWAYS sell fast. AS ALWAYS FIRST COME FIRST SERVED! SOLD OUT QUICK AGAIN!!!
