Wypada zaledwie daje jej życie przechodzić trybie i gnije wspólnota each button is continuous stim for each different collar. I'd prefer the ability to keep momentary stimulation with multiple dogs. This is all clear if you take the time to read the product which is available on Gun Dog Supply. By: Owns 2 dogs. I this collar. I have two beagles who to run the woods, and with this collar on they can run as much as they want and return to me with just a push of the button. Very easy to train them, and I especially the vibration option. Both of beagles return when I push the tone button, but if they get on a scent and take off, the vibration warns them, and they come running back to me. Couldn't be happier with this collar. By: Hunts. Family pet. The SD-425 is a nice device. It works as described on the Sport Dog website. Both the collar and hand control are small compared to other manufacturer's products. Gun Dog Supply is easy to deal with. Their website is easy to navigate. They shipped the order promptly. I would definitely order another Sport Dog product and would definitely order from Gun Dog Supply again. By: Family pet. I was skeptical about getting e-collar, but the large 8 month old puppy that I adopted was getting out of control. I did research and emailed for advice. He was very responsive and knowledgeable and made me feel secure choice. I also spoke with Customer Service after making online purchase and they also receive 5 stars. After watching both DVD's I had no problem effectively using unit. Loki's behavior is much more consistent and appreciated. Thank you for a great product! By: Owns 2 dogs. Family pet. Haven't had a lot of time to use it yet. But the times I have, has worked as advertised. It's easy to get started and easy to use. I the additional DVD for training. Had gotten a bad DVD, contacted GDS and replacement was sent immediately. I am looking forward to working more with dogs, and I have been very pleased with promptness of receiving order and follow up. Thanks By: Family pet. We are still training. She is a rescue, 2 years old when I got her. Stubborn, but good dog. Responds well to training when lead is use. Ignores me about half the time when off leash. But we have only had it for about a week, and it is holiday time, our schedule is a bit unusual. By: Family pet. I the trainer. dog has really responded to it, and the vibrating collar is a great feature. I 't have to shock her, I just vibrate the collar and she knows to respond. I do wish it had a little more shock at level 7 for the days she needs the extra correction. Had I to do it all over again, I think I would have gotten the 425S. By: Owns 3 dogs. The SD-425 seems to be a really well made unit. It has very user friendly controls, multiple features and options, as well as being very compact. Not only the controller, but the collar is very light and slim, yet seems very durable. I've used other training collars the past, including older Tri-Tronics unit that I was not near as pleased with, as I am this unit. It's a smarter design than I've seen or used. Even down to the ability to use it ALL day, then completely recharge it only two hours!! The Shepard I'm using it on weighs about 105lbs., is VERY active, and responds to a level 1 with no further stimulation needed. Great product!! I'd highly recommend it! By: Doberman Pincer. Family pet. The small size of both the controller and the collar are fantastic! Not too sure about the tuning dial, needs more levels, but he's growing 6 lbs a week! Gun Dog Supply is the best source for e collars. The video reviews were invaluable. Reviewed all collars here and compared prices elsewhere and bought here. By: labrador retriever. Family pet. The Field Trainer SD-425 is easy to use collar. I bought it to help reinforce commands when dog is out of sight or has a squirrel! moment. area is home to deer, and little quick movement animals even walking to the local park can be excersice Leave it!. The SD-425 quickly reminds 90lbs dog to listen. This is just another tool to use our daily training times, and it gives me a sense of relief to know now that I have the ability to remind dog that word is law, even 100 meters away. By: Hunts. Works great. 1 year old took to the SD-425 with 2 days. The reach is great. As as she hears the tone, she is paying attention. I very seldom have to use any other stimulation. She also loves the collar. If I put it on her, she knows we are doing something she loves to do. Have a hard time taking it back off of her. Great product! By: Product works great. The first unit I received was defective, but the company quickly replaced it, and I've had no problems since. I have a
