RE: E-collar questions
All of the E-collars brand prices are about the same =/- a few dollars. Before I bought my classic 70 I looked at warrenty, durability, simplicity. I asked around on pros and cons of each collar before I finally decided on the Tri Tronics Classic 70.
Remember they are to be used to enforce what the dog already knows not what he doesn't.
I run alot of hunt test and took 2 dogs to the HRCH level without the use of an e-collar When I finally bought one was when he decided to ignore the whistle on an upland test and wouldn't stop on the flush, so it took me about 4 years to decide on which collar to buy.
Good luck on your decision.
