D.T. Systems, Inc. Ultra -e- 2020
 

I am a hunter on a strickt budget. I realized the need of an E collar for corrections during training. I have Labs.

The 2020 has been durable. It has remained water-resistant during water retrieves. It is not rechargeable (which I wish it was). The batteries seem to last pretty well. I have never went above level 4 stimulation with my young dog. That was on her worst day of training. The 2020 has either 7 or 8 levels of stimulation, I am not sure because I do not use it that high. My opinion is that high level is to keep the dog from getting hit by a vehicle or trying to retrieve a bird 450 yards out in a hurricane. For the price, this was a very good purchase for me and I especially like the vibration function. A great secondary correction aid.

On Bob' s scale of 1 to 10 with 10 being top of the scale, this collar rates
