Check this before you replace anything
Lost range is more often a flat transmitter battery or a hand wrapped around the antenna than a hardware fault. A unit that runs short on a full charge usually needs a battery rather than a new system. Work through our troubleshooting guide first, then charging and battery maintenance for the routine that keeps a pack in service longer.
Which part fits your model
Charger tips and battery sizes differ across the ET, EZ, PE and UL families, and the model number is printed on the transmitter itself. Send it to us and we will confirm the part before you order, or compare the families in the ET vs EZ vs PE vs UL guide.
Other wear parts: contact points and comfort pads, biothane straps, and holsters, leashes and accessories. The full range is in E-Collar Technologies gear.
