The product is exactly what I expected works great directions on setting mode could be more clear other than that I'm extremely satisfied

Walker coon puppy needed more power than a standard collar could give this one works just fine

This is the 5th 425s I have owned. Great collar for the novice and pro alike.

Easy to learn and utilize this tool, especially withthe instructional material Steve provides digitally and hands on.Thank you Steve!

Doesn't phase my 70 pound Doodle even on the highest setting.

This is my 2nd sport dog e-collar. The first one still works like new after 20(?) years. The only reason I ordered #2 is I need another charger for the truck. These collars are the best out there for a very fair price. I have several more expensive collars that aren't near as great as sports dog's.

I have been using collar for about two weeks on a 9 mo old Weimaraner, Gus. He responds well to tone. Have not needed to use electric stimulation. He has been in water and collar is functioning fine.

For the money, there is no better e-collar on the market. This model is especially suited for the field. It's light, compact, and nothing beats it for getting your dog's attention when he or she gets distracted by nature. In short, it's the only collar you'll need.

We picked this collar up to work with our Lab/Black mouth cur puppy. We have used the collar with great results in helping correct a couple bad behaviors that we were trying to train through with little success. Our dog is a rock star now and rarely ever needs correction other than verbal commands. The collar and controller are quality, the with the ability to be programmed fairly easily and the buttons and stem dial are very easy to use and can be manipulated quickly to aid in quick correction when needed. This was well worth the investment and really aids in training your dog but it is not magic and it takes work and time with your dog to get your desired results. This is a great tool to have in your training tool box.

This is my second SD-425. Not because the first one broke, but because it was so durable (had the first one for 3 years, used 2-3 times/week). Primarily used in salt water and sandy environments, none of the metal pieces show any signs of corrosion, and have had no issue with debris getting in the ports. I also use this for off-leash control at the beach, and consistently swim with the remote tied to a belt loop. The collar shows no sign of wear even though worn in timber and brush. Multiple intensity levels make it easy to dial in to your dog's sensitivity. Highly recommend!

I love it. Turned him from being extremely disobedient and unfocused to a focused, obedient hunting buddy. He now retrieves and stays by my side, don't think I could've done it without the collar. Love it, best dang thing I bought in a long time, well worth it.

I was skeptical that there was any collar that had enough voltage for my wide open 2 year-old. He does great with the 425 and I don't have to go above low range, level 2 about 90% of the time. Great product!

Very good quality. Performs as expected and does the job it was designed to do. I highly recommend it to anyone in need of a training collar. Thank you!

I am very happy with the SD 425 collar. The collar is easy to use if you follow the manuals. The transmitter is pre-set (although you can change settings if you desire) and has been a great addition to my dogs training. Thank you!

So far it works great! Video was very helpful in understanding the proper use of the collar. Happy with the product.

Super simple and like the size.

Working great so far. Held up in salt water also

Love the collar. Easy to use.

Hands down exactly what I expected. My dog listens to all commands off leash no problem. Highly recommend Freddy king's YouTube videos on introducing the e collar.

Our dog is very stubborn when she wants to be! With this collar she doesn't even hesitate to listen to every word! It has went from her just looking at us when she knows what she should be doing to actually doing it without hesitation. Very happy with this product!

Very happy with this collar. Had one of the sport dogs earlier models for my last dog. Was a horrible unit. Shorted out in my hand and left two burn marks on my palm. This new collar is by far a superior unit over the older models. It's great for charging and with perfect range. Well done!

Great product. Easy to handle. Solid. I like the fact there is two modes of stimulant. One thing that could be improve is the vibrating mode. My hunting dog does not seem to feel it that much, but overall very satisfied.

Holds a good battery, and all the variable settings allow me to condition my dog to the appropriate stimulus settings.

Exactly what I was looking for in an e collar. Fast shipping/hassle free check out.

Works great.

The collar works awesome. I would recommend for any dog. My dog is like a different dog with collar on. It is the best money spent!!!!

Great product, and simple to use with good results.

I love it. It does great for what I need and for my labs!

Excellent product. Commands are now followed with and without the collar on.
