Anyone use this model? It's different than the G2 from the research I've done. I got a model for free, no manual but it had the collar, remote and both chargers in a case. The guy told me he bought it for his lab a few years back used it maybe 10 times and gave up on the dog for whatever reason. It has 5 settings, one button. You can nick or hold continuous up to 9 seconds depending what you need. Not sure on the range, I think he told me a half mile but haven't verified that.
My question, this was free so obviously no feelings hurt if you tell me it's a piece. Free is free though, will it get the job done or do you really need the nick/continuous buttons and 10 levels to get it done?
