Perfect for training my hounds!
I have a couple of hound wannabes and when we go out to work the fields they often forget to listen to dumb ole dad. It only took a few blasts with the shock function to get them to stop and pay attention. I now use the vibrate setting and they pay wonderful attention.

I run two of the '425S' units in tandem. Doing this allows me to have two remotes that can control either collar. That way when my lady friend and I are out running the dogs we can have independent control of either dog.

Also, buy the LED Light kicks butt for camping!

Thank you so much!


PS- Wonderful customer service and support!!!

Great idea
I love this product and have recommended it to so many people! We trained our very stubborn lab with it since she was 5 months old (exactly why I love the vibrate and tone options.)

Unfortunately, we have had to return this product 3 times in 2 years and tonight we will be returning another. I don't know anyone else who's had issues and it's very frustrating but after a few months it fails to work.

All I can say is just beware for people who solely rely on it for the safely of their pets.


We are very sorry to hear that you've had continued issues with your remote trainers! If you are still having trouble or have any problems in the future, please be aware that we may be able to solve the issue through troubleshooting and, if a replacement is needed, the product has a warranty that covers most situations. Please give us a call at the number 1-800-732-0144 and we would be more than happy to help out!

Best thing we ever did for the safety of our beloved dogs
We don't have hunting dogs, but 3 Labs, all swimmers. We bought these because another brand broke in the first six months. We've owned these for over four years.
We have lots of stupid neighbors that leave out garbage for deer, bears, etc. So our dogs are always trying to sneak away. Almost killed one of our dogs who ate garbage and after a $2,000 vet bill, all 3 wear their collars fulltime. When they go outside, I turn them on. With only a shock once, all of them respond immediately with just the beep. Now I can enjoy outdoor living with my dogs without having to worry about them getting hurt.
