The system features Innotek's patented run-through prevention to keep your pet in your yard. The collar is waterproof. It continues to function even when submerged. This is a safe, rugged, reliable system.

Innotek's UltraSmart Electric Dog Fences give you the added flexibility of being compatible to Innotek's older pet containment systems as well as their indoor Zones system. The IUC-4100 collar works with the SD-2000, SD-2100, SD-2200 and Zones indoor containment discs.

This product features Innotek�™ s new UltraSmart technology. ReadyTest ensures that your dog�™ s collar fits properly. The collar emits an audible click to inform you when the collar is properly fitted.

The collar performs its own on-board systems check. Each time after charging the collar runs its own diagnostic to ensure that it�™ s working properly. Power and electrical circuits are checked providing added safety for your pet. A green light tells you “all systems go” while a red flashing light signals a problem with the training collar.

The 3-way battery indicator helps you never run out of power. A green light tells you that the batteries are half charged or better, yellow means that the charge is less than half, and a red light tells you its time to recharge the collar.
