A durable and reliable collar offering both comfort and functionality, the Innotek UltraSmart is contoured to fit the curve of the neck without the bulk of other collars.

The integrated rubber collar band with buckle closure achieves a proper fit and is more durable than fabric bands and also minimizes odors. With no external controls or buttons the collar is completely waterproof.

The collar fits dogs with neck sizes of 8”-22”. The adjustable correction levels are suitable for most dogs.

The Innotek UltraSmart Collar features three progressive levels of correction as well as a tone-only mode. The correction level is set at the transmitter rather than on the collars; this means all dogs on the system are subject to the same correction level setting. The unique ReadyTest feature ensures a perfect fit every time by performing a self-diagnostic to confirm collar contact and functionality.

The collar is rechargeable and charges in a cradle atop the transmitter unit included with your Innotek UltraSmart electric dog fence system.

We have an Innotek collar and charger that is 9 years old. It has recently stopped working. We are trying to figure out what model it is since we can't find our paperwork. I will list the numbers on the back of it to see if that could help figure out which model series it is. They are M025401 A
and 0505001519. I would appreciate your input. Thanks!

Sorry Angie, Those number do not help. If you would like to take a picture of your equipment and email it to me I would try to match it up. If your equiment is 9 years old investing in a part to keep it alive my serve to be futile. It may be time to upgrade to a new system. Please give me a call so we can discuss all options.

we have an inntoec uic5100 inground system with the rechargeable collar that looks just like this. Our collar no longer holds a charge - can we replace the inside batteries or do we need a whole new collar? Would this collar work? mc


Hello MC,

Unfortunately, due to the waterproof nature of these collars -we do not replace the internal, rechargeable batteries, nor do we offer replacements that the customer could install themselves.
My best suggestion would be to contact the manufacturer (now PetSafe, formerly Innotek), and see if they would be able to offer such a service.
