DT Systems SPT2420 Super Pro e-Lite Trainer, Water Proof

We bought this training device not so much for training, but as a device to be able to call our dog over long distances to let her know it is time to come home. We did test the unit by driving more than a mile from the collar and then sending a mild shock and a vibration to the collar. Both signals were felt by the person holding the collar. Upon following the training directions of teaching the dog the command to return to us, she began to get the idea which then altered the requirements we had for the collar.I like to take long walks with our dog {11 months old} and allow her to experience everything on her own in safe enviroments. She has a tendency though to be able to locate deer very quickly and once she's honed in on one she's focused on getting to that deer or deer if there are more than one. Once in pursuit she'll follow until they outrun her which is about 300 yards or more. This collar is one of the very FEW that operate at distances greater than 100 yards!!! Our needs have quickly turned from wanting to be able to call her back to us to having the peace of mind of knowing where she is and that she isn't hurt.Presently we are trying to return this model having only testing it and NOT using it, for the model DT-2430 that contains the beeper/locator which runs about $70 more. Unfortunately our 30 day window expired while we were out of the country on a medical emergency so it looks as though I will have to find an alternate method of selling this to purchse the model we really should have gotten in the first place. This is a great tool, I don't believe in shocking my dog, but the ability to vibrate her collar and have her know that means return to us is INVALUABLE, especially since I am the only person in the house that can whistle loud enough for her to hear me when she is out of site.

Came recommended by a professional trainer during a clinic I attended; he demonstrated the 'vibe' and range of stimulation and, more importantly, when to use each. I needed another collar for a second gundog, but chose this over adding a second collar for my other system. Would be nice to use one controller for both, but it like these features enough to just carry two controllers...
