I'm a Tritronics fan...but I was converted to DT Systems last year by George Hickox at his class. Not just any DT Systems collar, the ir 2420 collar in particular.
This collar is the only make that I'm aware of that has the ability to not only go down very very low in voltage, but also very fine adjustments upward (50 levels), along with a nick, continuous, jump, and rise features, all in one.
I'm convinced that for training in the yard, there is no better solution today. The lowest level, I can't feel, yet my dog responds to it for a que in training. The "jump" feature allows a very low stimulation setting for training and a higher (any level) setting for the "jump" button to be used as a correction. The "rise" button is for those times that your dog has an adrenaline rush and is chasing that pheasant flying away down the field out of control and you've underestimated the power necessary on the "jump" button to get compliance from the dog. Holding the "rise" button down will let the power increase to full power over a few seconds, but will stop on your release of the button. So, you have 4 buttons to get whatever you need, instantly.
The ability to have a low and high button is not just for "...if he doesn't comply on the low, go to the high..." use. It's part of a training method of "notifying" the dog of a wrong with a very low stimulation, and "correcting" with the higher stimulation. This notifies the dog with low stimulation that what he was doing when he felt it was wrong, then the higher stimulation is the punishment. This is part of a training regiment, not a "hang it on the dog and try it out in the field" method. With this method/collar combination, I've noted that my dog needs less stimulation, less often.
The transmitter is bigger than some, but not unwieldly. I've used mine a full season and off-season training. I wouldn't go back to another brand until they met or beat these features. Personally, my opinion is that the Tritronic has the best build quality in the industry. But I'm not going back until they put equivalent or better features in their collars.
