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 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
$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.
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.
Easy to upgrade to 2 or 3 dogs without loss of tone/vibration feature
Up to 21 levels of continuous stimulation or 7 levels of momentary stimulation depending on transmitter mode
DryTek waterproof design -- submersible to 25 ft.
2-hour quick charge Li-Ion batteries that are also user replaceable (3-5 year lifespan with proper care)
50- to 70-hour run time on a full charge
LED battery charge indicator lets you know transmitter is finished charging
Small enough to hang from the included lanyard
Weighs only 2.4 ounces
Measures 1 3/4" W x 5 1/4" H with antenna
Transmitter MODES
The SportDOG 425X gives you the option of customizing the transmitter to fit YOUR needs. It also allows you the option of changing the stimulation setup as your needs change or if you want different options in different situations.
Modes include Continuous and Momentary with Tone or Vibration. Two or Three Dog Mode features one button per dog with either Tone (Mode 3) or Vibration (Mode 4). You also have the option of Continuous and Momentary with Tone and the ability to activate/deactivate the Locator Beeper (sold separately).
Change MODES in seconds by setting the transmitter dial to the mode you want. Next press the recessed button on the back of the transmitter. The transmitter light then flashes back the number of the mode you have selected. Modes can be changed as often as you like. Change them for different situations or training styles.

Another feature in the 425X collar is the ability to change stimulation settings at the collar. The collar has a low and medium setting. This allows you the option of finding the correct range of stimulation for your dog. Lower the overall stimulation choices for more sensitive dogs and raise the levels for hard headed or stubborn ones.
You can change the collar setting at any time. You can also have collars set up on different levels and work them from the same transmitter. This allows you the option of working sensitive and stubborn dogs from the same transmitter.

Intensity levels can be quickly adjusted with the dial on the side of the transmitter, meaning you can instantly adjust intensity whenever distractions increase
Teach yardwork/obedience and enforce known commands with lower levels of stimulation
Use higher levels to stop unwanted chasing or to overcome strong distractions
Up to 21 levels of continuous stimulation or 7 levels of momentary stimulation depending on which transmitter mode you choose
SportDOG SD-425X Range
500-yard range, which is ample for most dog training or for hunting with close-working field dogs. Actual range depends on training conditions, including weather, terrain, presence of cover, etc.
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.
Pros
Confidence that it works every time.
Cons
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 enclosedBasic 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.
Pros
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.
Cons
Found in a Brick n Mortar store at same price. Could have avoided shipping cost.

I purchased a 2 dog system from Gundog supply for my 2 shepherd pups. Couldn't be happier with this purchase from them. It also came with very detailed instructional videos to assist in the training....I have had labs my whole life that have been extremely easy to train....shepherds are slightly more challenging with a different mind set. These collars have given one more tool to aid in the training.
Pros
Super easy to use

Broke the pup from chasing chickens and stealing food in the kitchen in 1 day.
Pros
Waterproof, reliable.
Cons
I wish the warning tone and vibrate features could be "both", rather than one or the other. Vibrate and tone should also activate with shock so the dog associates these sensations with the correction

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.
Pros
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.
Cons
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.
Pros
Plenty of stimulation settings. Intuitive control layout. Nice size. Long battery use on single charge.
Cons
Could use better contrast of the numbers on the stimulation dial. They can be tough to see in marginal light.

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.
Pros
Everything about this product is nothing but PROs!
Cons
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.
Pros
easy to use
good phone
history of use - 4th collar purchased
hardy unit for bird dogs
Cons

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!
Pros
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.
Pros
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.
Cons
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.

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.
Pros
o Stays charged for very long.
o Charges very quickly.

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!
Pros
Great instruction DVD and it works!
Cons
Haven't found any yet

This collar is exactly what I was looking for to train my 1 year old German Shepard. He is very sensitive to e-collars so the option for Vibrate/Tone is perfect for him. However, it does go up to a level 7 if needed! I loved that it came with a DVD and information packet if you are new to e-collar training. Shipping and communication were excellent as well!

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

This is a great choice for smaller hunting dogs like my Brittany. Some I have tried are just too bulky and heavy for a 30 pound dog. Love this one. Simple to use too.
Pros
Good size for my Brittany.
Cons
The contacts are a bit long, in my opinion, but dog I'd doing ok with the. I would like to see a shorter option with the setup.

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.
Pros
Easy to use, easy to follow instructions, battery life. Great training DVD.
