They do have a rheostat system. But it has never been a problem for me acquiring the same stimulation level. The dial is marked with numbers/notches. The gradual increase of the rheostat system allows me to adjust for just the right amount of stimulation needed to get a response. Once I have found that level I rarely have to change, and if I do... it is just not a big deal (for me at least) to adjust. I think it all boils down to what your used to.
I had Innotek collars (before I learned my lesson

) that used a seperate button for different levels, and the jump from one level to the next always felt to me like a larger step than the rheostat system of the Dogtra.
I think where Dogtra collars really shine is for the Hunter who will use his collar predominately for hunting, but wants a collar that can do a decent job as a training collar if needed. Just me, but I think their collar/beeper models are second to none.
