Listers, I've had this device for a long time, but it's still out there as the last time I wrote ya'll about it, a number of folks appreciated it and told me so. Ok -- BARK FREE is the name of it. It was developed by Vet Techs and emits a sound that you can adjust so that a human won't hear it or if you want, you can fix it so you can hear it. It's in a waterproof vinyl little box LED status indicators, wall mount bracket, 50 ft. electric cord, audible test button, The model I have is PC06 Their phone for questions is 888-3-LENTEK Their website is www.lentek.com After my post yesterday, I've had bunches of responses with more questions, so I thought it best to just tap out this stuff for all of you in case you want to find out more about it.
