RE: Used E Collar
If the collar was only used for a week and the batteries are ok....$200 is a bargin. I've upgraded to "new" technology a couple of times and have sold my old collars for more than $200.
Why did I sell them? I upgraded to a 2 dog unit instead of having 2 single dog units. Both had been used hard for 3 years with absolutely no problems. If the unit is less than 2 years old...it's still under warranty.
One thing is for sure, Tritronics makes an excellent product and stands behind it 100%. I had to send a beeper back to them once. It was out of warranty by about 2 months...they replaced it. That was 3 hard hunting seasons ago.
Do yourself a favor, go with TT. By the way, I'd strongly suggest that you get some training from a professional before strapping an e-collar on your dog.
