Innotek is a premier dog fence brand. Innotek is owned by Radio Fence, the parent company of the Invisible Fence, PetSafe, and SportDog brands. Innotek's primary differentiator is the use of rechargeable collars. This feature allows owners to simply slip the collar into a recharger instead of buying special batteries every couple of months which is a major time and money saver. The main drawback to Innotek systems is that you cannot independently adjust the correction levels for each dog on the system. This flexibility is useful for owners with two or more dogs of different sizes.
Innotek's full featured system the UltraSmart IUC-4100 includes a slimline collar with a lithium ion battery. It's sibling the UltraSmart IUC-5100 adds a remote correction function. Both systems include features that help owners properly fit their collars and are well designed for usability.
Innotek also makes the SmartDog SD-2100 which is their basic rechargeable system. The SD-2100 boasts fewer features and comes with a larger NiMH battery powered collar. Innotek also has a basic non-rechargeable model the SmartDog SD-2000. The SD-2000 lacks a few basic features we view as necessary to effectively train your dog.
