The smartest hidden fence on the market.

New, sleek, streamlined comfortable collar -- 30% smaller and lighter than other containment receivers. New ergonomic collar shape assures better contact and won't turn on your dog's neck like older collar boxes do.

Test circuitry that automatically alerts you to critical system problems, battery charge status and whether the collar is fitted properly - all information that you need to know to ensure optimal performance and that you need to know BEFORE a problem becomes a catastrophe.

IUC4100 Hidden Fence Systems Feature:
• Expandable for as many dogs as necessary - just purchase add-on collar receivers
• Fence wire can be buried or left exposed. Can take less than an afternoon to install in the average yard.
• Advanced technology ReadyTest™ tells you when the collar is fitted correctly - produces a brief audible click from the collar to assure you that the collar is making perfect contact.
• Contoured collar fit for greater comfort and better, more consistent contact.
• Waterproof - Collar and transmitter stand up to rough punishment, even submerged in water.
• Your dog will be warned BEFORE he gets to the hidden boundary. Variable warning zone range can be set from 1 foot to 12 feet from the hidden wire. Fast-running active dogs such as terriers can get plenty of warning.
• Omni-directional collar receiver is more effective against boundary encroachment. It warns and then corrects your dog no matter how he approaches the boundary.
• Rechargeable Collar - Fast-charging, long life Lithium Ion batteries.
