DT Systems

never dealt with the tri-tronics. what are you referring to by in conjunction with the dc collars? can the dt be put on the dog and a dc collar having room to fit with pushing the dt around and making it loose skin connection? if so, yes. iv used the dt and a dc-30 and didn't have any issues with stimulating the dogs attitude. I set the dt collar high up on the neck, near the base of the skull, and the dc lower and a little looser so it don't creep upwards near the dt collar. as far as range, I can get about 500-800yds max out of it, depending on line of sight, but I don't like stimulating the dog unless I can see and confirm it is that particular dog doing wrong and correct the proper dog, not another dog by accident when it wasn't doing wrong.
