The new Dogtra 7100 H Series has a vibration feature built into the transmitter so the operator will feel when the stimulation button has been pressed and is operating. The unit is two-dog capable with one transmitter operating two collars. There are 127 levels of adjustable nick and constant stimulation with a half mile range.
A non-stimulating pager/vibration feature is included. User replaceable NiMH batteries have a two-hour recharge time. The transmitter has a LCD screen that displays stimulation levels in the dark as well as indicating battery life.
