Tri Tronics training collars can be used with one dog or with multiple dogs. The Classic 70 G2 Dog Training Collar is an electronic dog training device that can be used with as many as six dogs. One button controls five levels of constant stimulation, and an audible tone on this collar can be used to praise your dog for good behavior or warn it for bad behavior. This Tri Tronics electronic training collar has a one-mile range, so your dog doesn't have to be right beside you to receive proper correction.

The Classic 70 G2 EXP, which fits any dog, and the transmitter both have rechargeable batteries that are easy to remove and replace. The charging system that comes with this training aid can charge the batteries in as little as two hours. And, the batteries won't be damaged if you leave them in the charger after they are fully charged. The collar, transmitter, and battery compartment are all waterproof.

The Classic G2 collar comes with a carrying case and a basic training video and manual. And, the collar has a two year warranty.

TriTronics makes training collars for all sized dogs. TriTronics collars have multiple levels of nick and constant correction so you can choose which level of correction is appropriate for your dog. Some training collars have a range of a half mile, while others have a two mile range.

The Bark Limiter XS Bark Collar, which runs on Lithium batteries, is suitable for all dogs. The collar responds to the vibrations of the dog's vocal cords; the dog receives a mild electronic correction when it barks. The waterproof collar can be worn inside or outdoors. Only your dog's barking activates the collar and causes a correction, so your dog can wear the collar around other barking dogs and not receive a correction.

The Bark Limiter XS has five levels of correction. With the easy-to-read LED read-out, you will always know which level of correction the collar is set at. The company allows you to adjust the level so your dog is never over-corrected. The collar resets itself when the dog doesn't bark for 30 seconds, which also prevents over-correction. The bark odometer will let you know how many times the dog barked during the day. With a collar, your dog will learn to bark only when it's necessary.

Their line of beeper collars allow you to keep track of your dog even when it isn't in your sight. The Sport 65 BPR G2 Dog Training/Beeper Collar has a range of a half mile, and the Upland G2 Dog Training/Beeper Collar has a one mile range. Both of these electronic training devices have constant and nick correction as well as multiple levels of stimulation. The collars and transmitters are waterproof.

TriTronics sells accessories so training and beeper collars can easily be adapted from one dog to multiple dog systems. Antennas, extra batteries, chargers, and collar straps can be purchased separately for any of the collars. Dog training is just easier with electronic training supplies.
