DT Systems H2O 1820 PLUS Expandable

The collar works great! It fits my 27 week old female lab and will when she's fully grown. There was no better price than what Gundog Supply offered with the free shipping. The shipping was prompt and communications during the process was very good. They are to me a trusted site I have ordered from previously and will do in the future.

Excellent product! This product has met all my needs as a quail hunter, who enjoys watching good dog work, and also enjoys helping his dogs reach their full potential. Before, I didn't have a system with the beeper technology, and since this added feature has completely changed the way I hunt and train. I highly recommend this product to quail hunters that can't always have an eye on their dogs.

DT is a great training e collarI on my 2nd collar .if I lose anythingI can add a collar or buy a part.. I lost my antenna and had one in three days great when you're able to replace a part.

My third one of these great e-collars! The other two are still in service. Best I've found for my waterfowl hunting labs. Just a vibration and my dogs look at me and wait for directions. Reliable and easy to use. Highly recommended.

We love this dog collar! Bought one many, many years ago for our dog and used it for several years! Finally, the battery wouldn't hold its charge, so we bought this one. I am sure it will be around for many more years! Great collar - great quality!

Dt makes a good quality collar. My last one lasted 12 years. Only complaint with this one is, it didn't come with a 2 collar charging wire. I have to charge each collar separately. Takes forever.

Works great!

The collar is very stiff, and the clasp is not the best making collar somewhat difficult to get on the dog. However, once on it works as advertised.

Great product and Gun Dog Supply was super easy to work with and very fast. Will shop here again.

I have one of these units already, so this is my second purchase. Easy to use with the dogs in the field and in thick cover. The beeper feature is nice for locating when the dog disappears in the cover. Durability is key too. My first one is still in use and fully functional, and I've had it for four years.

Works great in the field, and easy for my wife to use when exercising the dogs.

This is a great product and very well made. I returned it due to the fact that because the beeper is permanently affixed to the collar, the collar only closes to a 14 inch diameter. This was too large to properly fit my Brittany. I opted to return it for a different collar that was able to handle neck sizes as small as 10 inches. The Gun Dog Supply customer service was OUTSTANDING! The exchange was flawless. Thanks Again!

This is by far the best \"point and beep\" collar there is. I have had my single for several years. I turn it on in the morning, hunt all day rotating it on my dogs as they get rotated. It never gives me any trouble whatsoever. I am buying the 2 dog system now as I hate to even run a dog unless they have one of these on.
