Cam,
The 2 brands I ould recomend are tritronics and dogtra. Both are very high quality, have good customer service and great reputations. As to which model, that depends on how and where you hunt. Range will very with model from a hundred yards to 1 mile. Remeber that these distances are under perfect conditions. IE: if you are in hilly terrain the 1 mile collar is not going to get that far.
Obviously you are not going to use the collar at 1 mile distance anyway as you are not going to be able to see the dog at that distance. However, I used to do Field trials and hunt tests so we trained at distances of 500-600 yrds so I had the longer models .
My collars are the tritronics 200 and the dogtra 2002 NCP. Both are very old so I don't even know if those models are still made.
Once you decide what distance you want ( more is better) then look at the different models in that range and decide which has the bells and whistles you like as well as the size and feel .
As was mentioned above , COLLAR CONDITION your dog, don't just put the collar on and start using it for corrections . Collar Conditioning is a specific technique that teaches the dog how to turn the pressure of the collar off and that the correction is coming for a refusal of a KNOWN command. Most collar conditioning drills start with a dog that knows the commands SIt, Here, Heel. You then use a sit , here, heel drill to condition the dog . You teach one command at a time before moving on to the next.
If you have never collar conditioned before, I highly suggest you either bring the dog to a pro to do so , or pick up Mike Lary's or Evan Graham's videos on how to do so .
Send me your email and I will send you and outline of how to collar condition. I too like to force fetch before CC but that is another topic.
Good luck,
