IRF-300D
We recommend the System with Deluxe Ultralight Receiver for any dog that is 6 pounds or over. With five levels of programmable correction, this is our most versatile, light weight, and advanced receiver collar made. You can increase or decrease the correction to meet your dog's training needs. At level five, the Deluxe Ultralight Receiver is strong enough for the most stubborn dog. The Deluxe Ultralight Receiver also has a low battery indicator light to let you know when to replace the battery. (Receiver Size: 1.7 ounces - 2 x 3/4 x 3/4 inches.)

IRF-300UV
If your dog is 20 to 50 pounds or over and trains easily, you want the System with Ultralight Receiver. The Ultralight has only one level of correction and does not have the low battery indicator light.

IRF-300S
If your dog is over 50 pounds you may need the System with Big Dog Receiver. With a simple push of a button on the dogs collar you can raise or lower the stimulus. Have each dog set differently, based on its needs. A True Warning: If your dog gets to close to his boundary a 3 second audible warning and (patented) vibration are given before the stimulus. ""Vibration"" is a big help when dealing with a stubborn dog. The warning allows your pet to choose good behavior and back up before the stimulus. Rising Stimulus: If your dog continues further in the stimulus will become stronger. Waterproof: Guaranteed for Life. Low Battery Indicator: Lets you know when to change the 9 volt battery.
