DT SYSTEMS H201850 Plus Upland Waterproof 12-23" Rechargeable Remote Dog Training E-Collar, 1800-Yard Range, 16 Stimulation Levels, Beeper/Locator

Collar and controller are durable and very easy to use. Does an excellent job of keeping track of my dog in very heavy cover.

Had the collar 6 months and the horn stopped working. When it was "repaired" it only worked for a few months before failing again. They covered it under warranty but the customer pays the shipping. If it is out of the 90 day repair warranty you are on the hook for all repairs as well ($90.) I returned it for the FIFTH time before I was finally given a new collar. I wasted around $170 in shipping and "repair" costs on this POS. When they work, they are awesome. It seemed after the first "repair" thay failed to waterproof the horn assembly and it would gradually fill with water. The new one is working well but I am not very optimistic.

This is a great product. My jack russel likes to run off and with this collar I can sound an alarm that helps me track her. This way I can know where she is and then correct her for running off. I had to modify the collar to fit a harness so she wouldn't slip out of it. The collar is actualy too big for my dog, but with the modification it works great. I don't have to use the stimulation hardly ever. She knows to behave when I put on the collar. She seems to be more obedient when she's not wearing it too.

I've used the DT beeper collars for at least 10 years. They are great when working, but the beepers are connected with wires in the collar and quit working. You have to send them in and wait 4 weeks to get them back. Not very convenient during hunting season. They used to stand behind them and fix for free. But now it's $90 every time. Bought a different brand.

I bought the D.T. Systems H2O1850 Plus Black Training Collar for training my German Shorthaired Pointer pups. The collar would not adjust down small enough for my pups neck.I contacted D. T. Systems about programming the collar and other product questions. When I finally got someone to speak with, all they could do was read the box to me and avoid the question. Then forwarded me on to a man who basically put it "If you don't want the product then return it." At which point, I obliged.Amazon was wonderful about the return, refunded my money before the collar was even returned. Giving me the ability to order the SportDOG SD 1825, that I absolutely love.

I am happy with my purchase, the locator alone is enough for my dog and I to continue staying within 10-15yds during training and in the field for birds.My one "compliant" which is more a knock on myself than this particular product, but I thought a vibration warning mode was included in this model. It appears that since I ordered the locator version, I lost that vibrate warning for the dog. My own fault, but as mentioned above, pushing the locator button is sufficient enough of a warning my dog is straying too far off.Great battery life.Lastly, it is also good for taking with to neighbor's houses also. My dog (Nico) stays close without a leash, very convenient and useful even in everyday.

DT is the best there is

Not for small necked dogs. Used this on my 50 # GSP, had to use the 2nd and 3rd to smallest size holes, this created a sharper angle out of the transmitter and within a year the wire to the beeper frayed and broke at that point.
