    What's New in the SportDOG SD-425X

  • Up to 21 levels of continuous STIM or 7 levels of momentary STIM with either non-stimulating tone or vibration (depending on transmitter mode)
  • Backward-compatible with previous SD-425 series remote collars

  • The SportDOG FieldTrainer SD 425X is SportDOG's smallest and lightest e-collar. The 425X is an incredibly versatile training collar, and is a good choice for all-around use including in-the-field training, hunting with close working dogs, or training in the yard.

  • Both the transmitter and receiver are waterproof and submersible.

  • The 425X can be expanded to control up to three dogs by adding SportDOG Brand Add-A-Dog collars.

  • The comfortable "soft coat" transmitter finish makes this unit a pleasure to handle.

  • The no-look design allows you to keep your eyes on your dog and not on your transmitter.

  • The low continuous stimulation levels and gradual increases between levels on the SD-425X are particularly useful with sensitive dogs or breeds.

  • You can customize your SportDOG Field Trainer SD-425X to match your training preference. It comes set up in MODE-5 (a 21-level continuous one dog collar with non-stimulation tone), but it can easily be changed into 7 different modes with different button configurations.

  • Gun Dog Supply Exclusive: One Hour BASIC OBEDIENCE Ecollar Training Video

      SportDOG Field Trainer SD-425X Remote Training Collar$40 Value -- You get this FOR FREE when you buy this ecollar.

      We are proud to announce that Professional Dog Trainer Robin MacFarlane is working with us! We just wrapped another video shoot, and are launching her latest DVD.

      PREVIEW: Watch a 10-minute Preview here...

      What's interesting about these videos is that Robin has never worked with these dogs before, and several younger dogs have never been trained on an ecollar.

      First, Robin walks you through the basic obedience commands showing what proper form looks like.

      Next, Robin shows how she introduces the ecollar to two of Steve's puppies, Jack & Tilly, and shows you how to find the right STIM level to communicate with your dog.

      She then turns that into a lesson for your dog to recognize that STIM means pay attention to your handler and expands that into a basic recall.

      Additional segments include teaching RECALL, PLACE, SIT, and HEEL.

      Exclusively available at Gun Dog Supply.

    SportDOG SD-425X

    Gun Dog Supply EXCLUSIVE

    One hour of BASIC OBEDIENCE training
    from Pro Trainer Robin MacFarlane.

    The 425X is the replacement for the extremely popular SD 425. The "X" version adds two 21-level STIM button configurations (transmitter MODES 5 and 6) for more increments between levels with either non-stimulating tone or vibration options.

    The features of the 425X include:

  • Up to 21 levels of STIM depending on transmitter mode
  • Rapid 2 hour charge
  • Collar mode selection options for sensitive and regular dogs
  • Smaller collar
  • Tone and Vibration options
  • Multi dog modes that include Tone or Vibration on the dial, allowing you to use tone or vibration when in a two or three dog set up

    The 425X is a great collar for obedience work, retrievers and flushers. It's going to quickly become one of our best sellers in its category.

    The 425 has been our best selling collar under $200 for the last few years, and the 425X makes that system even more versatile. It is an awesome system for folks that don't need a lot of range but want a full-featured system for working close to medium range dogs.

    While hiking in the Rocky Mountains of Montana, I need to have control over my dog to keep him from chasing wild animals such as grizzly bears and mountain lions and wolves. That would be the end of my labrador retriever Wally if he ever got near one. Now I can hike with confidence knowing that SportDog 425X can reign him in when he gets too far away. I can take hikes that I previously could not.
    • Confidence that it works every time.
    • Nothing I can think of.

    Gun Dog Supply & sd-425x was Recommended by our Instructor.
    July 20, 2022
    Gun Dog Supply delivered confidence.
    They did it in less than 48 hours too.

    The enclosed
    Basic Training Manual gave me new understandings and increased communication skills.
    Tutorial CD was better than any YouTube videos I have been watching in preparation.

    These 2 factors gave me the confidence and knowledge to know what we wanted to accomplish and how to go about it without hurting my dog. The results are impressive & I’m still waiting on my Instructor to schedule that 1 on 1 training session on how to set up and properly use this recommended piece of training equipment.
    • Recommended by our instructor.
    • ***** Basic Training Manual & Tutorial CD,
    • Solid heavy duty waterproof build is rugged & feels good in your hand.
    • Well designed Compact transmitter can be operated effortlessly in right or left hand without error.
    • Range 1500 feet or 500 yards & 70 hours operation on a 3 hour charge.
    • My German Shepard responded positively and was not hurt in the process.
    • Found in a Brick n Mortar store at same price. Could have avoided shipping cost.

    Replaced a SportDOG I had for 4 years.
    May 27, 2021
    Works fine, liked the previous button for sound only without turning the knob.
    • The range of shock is great, I rarely need to use the collar and then at a barely noticeable level.
    • Feel I must test on mysefl every time as I find the different level settings not easy to remember.
    • Like the mild setting.

    This training collar helped with Blaze's training so much. He did great on leash, but once he was off leash, it was a big of a struggle. We followed the tips that came on the training DVD and they work great! Blaze does not mind the collar at all and gets excited when we get it out to put it on. He knows he is going to get to run and work.
    • Easy to use, easy to follow instructions, battery life. Great training DVD.

    Sport dog e-collars
    March 24, 2021
    The Sport Dog e-collars really are “gear like we would have designed.” Our English Setter is always busily birding when we are outside. The e-collar let’s us call her in when we can no longer see or hear her. Rarely do we need to use more than the tone button as she is well trained with these collars. We also use an e-collar for our Golden to discourage him from approaching everyone we meet while walking. (He thinks everyone wants to pet a Golden). We only use the tone on him—he learned quickly to return at the tone even even though he was six before we introduced him to the collar.
    • These collars are waterproof and appear to be comfortable for our dogs.
    • We have discovered that salt water and packed sand can-after three plus years of such abuse-cause the collar to "die."

    Works well for us
    February 12, 2021
    After borrowing a different model from a friend we purchased this one since we did not the range the other offered. Once we got used to the different model we found this one to meet our needs. It is easy to use- I like the size of the transmitter and the range is sufficient. Our dog learns quickly and we rarely need to reinforce our commands. We adopted our lab a few months ago (she is about 3 yo) She ran wild in the woods behind our house when let loose, but now stays with us. We are also able to take her XC skiing and ice fishing and my husband is looking forward to pheasant season. The collar was also effective when training her to stay and wait.
    • Size of transmitter.
    • The only con as compared to another model is that the tone button is not accessible without turning the levels dial. It would be nice to have its own button.

    Very good all-around training collar
    January 17, 2021
    We have used Sportdog ecollars to train our dogs for years for indoor and offleash obedience, hobby sports, and focus and attention training around our chickens and other animals. I recently purchased the Sportdog Field Trainer SD-425X system for our 6 month old Siberian husky pup, and it has made all the difference in our focus training and obedience. The wide range of stimulation levels along with a vibration/tone setting allow us to use just the right level to get his attention without scaring or hurting him. He is learning to focus on us when we give a direction, and he is happy to do it! He is swiftly mastering obedience in high distraction environments and has mastered offleash recall from a distance. The collar system came with a training dvd and long-line which were also helpful in offleash recall training, whether you have experience like we do or are new to using ecollars. This is a solidly made but lightweight, comfortable collar that our pup doesn't object to wearing. He knows when the collar comes out, he gets to have fun! It is everything we hoped for and come to expect from a Sportdog collar and worth every penny.
    • -Compact
    • -Lightweight

    My Brittany is finally listening!
    January 13, 2021
    My girl is a pet dog but has the need for speed. I take her off leash in my neighborhood and on trails or the beach. I started with a cheap collar off Amazon but she would get too excited and ignore it. I can turn this collar up when needed and get her attention. It’s always a risk off leash, but I’ve learned these bird dogs need the exercise or they’re destructive. This collar provides a safe alternative.

    Great for rural pet management
    December 30, 2020
    I purchased this collar to replace a "pet park & yard"- grade collar that was not powerful enough for our needs. Our dog Callie is both a skilled fence escape artist and an enthusiastic varmint-chaser. Too often, we'd discover she'd escaped the yard and was free-ranging our ten acres or the neighbors' pastures with no way to call her back as the collar we had was either out of power or beyond range. This collar is perfect for our needs; it holds power for more than a day's use, withstands mud and rain, recharges in a couple of hours, and is powerful enough to call Callie home even through trees.
    • Long-lasting, quick to recharge, works in rain and mud, easy to set up and use.
    • The charging cords do not fit snugly in the collar and handpiece slots making it tricky to position the cords so that they don't fall out of the equipment while charging.

    Perfect collar for our Australian Shepard
    October 7, 2020
    Our Aussie, Darby, is very smart and has been easy to train. I really like this collar as it is sturdy and very easy to put on. The collar and buckle stay in place when put on per the instructions (snug). I have the remote set to 1 and my dog reacts (flicks his ears) to the low 1 stimulus; I only have to use the 1 medium stimulus if he is extremely distracted as the medium 1 stimulus gets his attention immediately. I love the lanyard for the remote which keeps me hands-free if we are using a leash. I'm very impressed with the product overall and I really enjoyed the training CD. Great product and I highly recommend it.
    We visit the beach often and will see how well this remote collar holds up after exposed to salt water. We will follow the guideline to wash with clean water after each exposure. Our previous remote collar did not hold up to the salt water exposure. The result of this exposure will certainly impact our overall review of this remote training collar.
    • The collar is very well made and the buckle is easy to put on our dog. I trimmed the collar length once I was sure of the size and fit. The small remote is easy to use and I really like the raised button on the medium stimulus - easy to find by touch. The lanyard has been great for me as I am hands-free with the remote when we walk our dog (Darby) on a leash. I am very happy with this remote collar and its accessories. Thank you Steve for the informational training CD and your follow up. I have been extremely impressed with your company.
    • I do not have any Cons at this time.

    Training new Lab puppy
    October 7, 2020
    I’ve been training my new lab puppy -Stella for the last 3 months. We got her at 8 week old and at 5 months she had all the basic commands understood. I followed Dokkens hunting puppy training DVD. At this point I purchased Sportdog field trainer to reinforce those learned commands - heel, sit, down, come, place. At this point Stella is very good at all commands with a 50 ‘ check cord. Over next few weeks I’ll be removing check cord and lease and I’m confident I’ll have well trained lab at the 6 month point! Everyday is an adventure with Stella but so far so good!

    Its a miracle
    September 17, 2020
    This product has been amazing for us! We got a rescue dog, a large hound, at about a year old. He is not an aggressive dog, but he is big and loud and was hard to control. Sometimes he would have barking fits and it was overwhelming. He knew some commands like sit, but would not perform them with consistency. He got out a couple times and it was terrifying because we live in a semi urban area with traffic, and we could not catch him. We were having second thoughts about keeping him, even though he is a sweet dog when calm. An e-collar was recommended so we purchased this product.

    I watched the enclosed DVD and got started right away with the method from the video. I'm not kidding when I say that within 2 training sessions, he was sitting, coming, staying, heeling (sort of) with consistency. I only used the beep function and the lowest shock, which feels sort of like when you touch your tongue to a battery, but less intense. Now, after a week and a half of a couple 15 min sessions each day, he obeys most of the time just seeing the transmitter. Sometimes he needs the beep, and sometimes the shock, especially when having a barking fit, but mostly he just needs to see the transmitter. Before, at walk time, it was nearly impossible to get the leash on because he would bark insanely and jump up on me. Now, with the e-collar, he will sit and stay while getting the leash on. He will sit and stay on a walk when we see another dog. Even my kids are doing training sessions with him and he is obeying our 10 year old. It is so awesome! I could not be more satisfied.

    Merchant Response:Mindy, Thanks for the review! I'm glad to hear SportDOG SD-425X has made such a difference. Give us a call at 1-800-624-6278 and one of our Product Specialists can help out with any questions you have about the system's operation. Thanks, Ben
    • Easy to charge, easy to use. The charge lasts a few days (I think). The strap/lanyard that comes with it makes it easy to keep the transmitter with me. The low shock level clearly does not cause him any pain.
    • The info on the DVD and in the written manual are contradictory regarding training strategy, so that is a little confusing. I have only used the side button, and I don't really understand the difference between the 3 buttons. It isn't obvious to me when the battery is getting low.

    December 18, 2023
    I've been using it for about 9 months and I must say it works great. My dog does not hesitate to get the collar on. It has worked well in all weather conditions. I must say this has been the best purchase I've made in 2023.
    • For my dog this is a complete system. The tones work well. The level of adjustment on the vibrations is good, I rarely have to go above 3 and the tones generate the desired response most of the time.
    • The side button came off early on the transmitter. I have ordered a replacement transmitter.

    This 425X trainer is a great product for training big dogs like a Dogo Argintino. Zeus was just a pup when we started using the 425X and his behavior and training has been awesome.

    Works well for retriever training and in the field with closer working dogs.
    • Plenty of stimulation settings. Intuitive control layout. Nice size. Long battery use on single charge.
    • Could use better contrast of the numbers on the stimulation dial. They can be tough to see in marginal light.

    I am learning to use this collar. The basic booklet was very helpful. Important to use for training and not as punishment!

    Excellent Service Dog training alternative
    April 20, 2023
    This product is superb as a last resort training device when all other training methods have not been successful. After about a week or so of continuous training with this product, a canine is very obedient and follows commands right on cue! Only need to occasionally break it out from time to time as a refresher training assistant. It is a little difficult to judge how tight to get leash on long haired or thick necked breeds, but with a little attention and time, and was thankful for the additional set of prongs that come included with the entire product.
    • Everything about this product is nothing but PROs!
    • When placing an order, and the customer puts the breed type down, the prongs need to match that type of breed. Example: German Shepherd requires the long prongs, so the short prongs are of no use, due to their thick hair and main around the neck.

    great e-collar
    September 29, 2022
    This is the 4th SportDOG e-collar I have had - all have been great products. Had issues with mode change on this one but issue resolved over phone. You need to press fairly hard and deep in the back to change mode. Was instructed to use the collar clasp instead of a pen to press the node change button and problem resolved - thanks for a good product and timely support.
    • easy to use
    • good phone
    • history of use - 4th collar purchased
    • hardy unit for bird dogs
    • none

    We got this for our 5 month old Airedale Terrier. When she was on the leash she pulled terribly and when off she had selective hearing. This collar has corrected both problems. Within two days she was responding immediately when called and walking beside me on a loose leash. It has corrected a lot of behavior problems. I highly recommend this collar.

    I needed an eCollar for my young male Boston. I wasn’t sure what style or size to get for him. Steve answered my email promptly and gave me great recommendations…with no sales pressure. I was impressed with the product and his approach and order it within a couple of days. And it was shipped promptly!
    • Perfect for my 29-pound maniac. I have used eCollars on my larger dogs so I found this very easy to use.

    A Good Product Gets Better
    January 21, 2022
    I bought the 425x trainer to replace the previous version. The stimulation adjustment knob broke off the old one in the field and disappeared. The new trainer has many more levels of stimulation than the old version. This is not a huge advantage for me at the moment since I have what trainers call a 'soft' dog. She doesn't need much more than tone or vibrate to remind her not to chase a rooster out of gun range. I've never used a stimulation level greater than 2 on my old SportDOG trainer. It may become useful for my next dog, who may not be as soft as my current lab.
    I like the small controller, which fits nicely in a shirt pocket, and I really like the improved collar material (rubberized not plastic). The other improvement is an upgrade in the charger ports for the controller and collar. The prior collar and controller had charging plugs with marginal geometry for the mating ports. The 425x has a better shape to the connector, which seems to stay plugged in better.
    I would buy this again, and I recommend it to friends needing a training collar. I like the training tips book and CD that came in the package.
    Gun Dog Supply was very easy to deal with, and I'll buy from them again.
    • Small controller which fits easily in the hand.
    • Easy to control stimulation levels in the field. I can increase it or decrease it while not taking my eyes off the field or the dog.
    • Improved collar material.
    • Improved charging connectors.
    • I had to read the manual to figure out how to set up the controller. This flexibility was not available with the old collar, so this was new to me.

    We have had a collar before from another company but this one has more choices. You can use the tone, vibrate and shock. It’s so easy.

    The collar and beeper stay charged for extremely long. Easily more than 24 hours though I have no idea how long. It also charges insanely fast. Even within 30m I think. I just know pretty much every time I checked it after beginning to charge, it showed as fully charged.
    • o Stays charged for very long.
    • o Charges very quickly.

    If I recall, this is my third unit from Gun Dog Supply. The unit I had lasted for years. Very good product.
    • Easy to use and very convenient. I use as required whenever my german shepherd is out of line.
    • None, so far.

    Exactly what I needed!!
    September 5, 2021
    I raise Australian Shepherds (to work cattle) and have never used a training collar. I was at my wit's end over this dog who was even raised as a house dog but has pulled on a collar, refused to come when called all of her life (1 1/2 years old). Otherwise perfectly normal except very reactive to things around her - and distracted. I watched the DVD (very helpful) since I did not have a clue what to do with the collar. She knew one command well - "sit" and had a command to stay with me "with me" but ignored that one while dragging me along. One lesson and I was amazed. Started with it on 1 and it was 3 where I got a slight reaction. She is now walking beside me on a loose lead. I have not started on the recall yet as I want this down solid (been less than 2 weeks) but I am sure it will work for that. Thanks!
    • Great instruction DVD and it works!
    • Haven't found any yet
