Products & Features  Hidden Pet Fence products are the most advanced and most human in the business -- made right here in the USA. We use products that are fully customizable to your dog and with numerous features, so you have the confidence your pet will not only be contained, but comfortable as well. Our superior products keep us leaps and bounds ahead of our competitors -- not just in terms of quality, but in affordability as well. We invite you to learn what separates our products from others. The smallest, lightest, fully customizable collar on the market. At only 1.3 ounces, your pet will hardly know it's there! Can be individually programmed and works with most pet containment transmitters. Hidden Pet Fence receivers are more advanced and have more features than any other receiver on the market! Uniquely designed probes to provide your pet with comfort and safety. No steel pins or abrasive metal. Only the comfort of soft rubber will touch your pet's neck. The Gentle Spring Contacts are spring-loaded steel collar probes. The retractable spring action applies the pressure, allowing the collar itself to be worn more comfortably by your dog.  The spring tension applied when worn is the perfect balance between effective contact and minimal skin pressure, making your system safer and more effective. TriScan™OMNI-DIRECTIONAL ANTENNA No blind spots or "holes," because all our receivers incorporate THREE antennas ensuring full 360 degrees of signal detection. FlashAlert®- LOW BATTERY LIGHT No more guessing when to change the battery. Never purchase an expensive battery you don't need. This patented feature will flash brightly to alert you when the receiver battery needs changing. SafetyStop™ SAFETY SHUT OFF Most products offer some sort of safety shut off, but only Pet Stop® products will shut off AND STAY OFF until your pet is free from the signal. Other products cycle on and off. Only with Pet Stop® receivers can you feel confident of maximum protection from continuous activation. SmartReceiver® - Progressive Levels of Correction Our receivers detect both how long your pet stays in the signal field and how deeply they enter it. The longer and deeper your pet is in the field, the higher the level of correction. This means your pets won't receive more correction than they deserve while maximum protection is still there when needed. StayAway™ - Anti-Linger System With some products, pets quickly learn that the warning signal has no consequence. Not with Pet Stop® receivers. Our receivers calculate the time your pet stays in the warning field and gradually increase the correction level until they retreat. This saves battery life and, more importantly, reinforces the initial training and conditioning.
