Electronic collars have multiple levels of constant and momentary correction. Every unit, except the 1800 series, has the patented rheostat intensity control. The rheostat control is like the dial on a radio; it allows you practically unlimited intensity levels.
Some collars have a pager mode. The pager does not provide an electronic correction; it only vibrates to get your dog's attention. The pager is a great way to call your dog back to your side without giving it an unnecessary electronic correction.
There are Dogtra electronic collar models for both companion pets and sport dogs. One for companion pets is the 175 NCP
Dog Training Collar. These have low to medium power and are suitable for medium to large sized dogs that weigh at least 20 pounds. The transmitter is compact and fits comfortably in your hand. These have a range of 400 yards.
The 200 NCP Gold Dog Collar has many of the features of the pro-series, including the rheostat dial and pager mode. These have a range of a half mile. The 200 NCP is a two dog unit.
The 1100 NC Dog Collar is an affordable collar that is comparable to the 1200 and 2000 Dogtra electronic collars. The 1100 NC collars are light weight but provide adequate correction for smaller breed dogs. These only weigh 4.9 ounces; they measure 2.75 inches by 1.75 inches by 1.4 inches. The transmitters weigh 4.2 ounces. Although the transmitters are small, they are designed to be user-friendly and easy to control, even when the user wears gloves. The 1100 NC collar has a range of a half mile and was designed to provide correction for high-energy, fast moving dogs.
The units respond to the vibrations of the dog's vocal cords when it barks. Excessive barking leads to a mild electronic correction. Eventually, the dog will learn that excessive barking leads to correction and it will only bark when absolutely necessary. Using these products to control barking does not eliminate all barking; it only limits barking.
They are designed with the user in mind. Trainers say that electronic collars are easy to use and allow them to individualize training programs. People who use these collars say that the company is an innovative company that listens to their customers.
