By Ann Collins / August 9, 2021

Are you trying to train your pup? If so, you’ve probably noticed that’s not as simple as you expected and sometimes not even treats work.

If you need a helping hand, you might want to consider using an e-collar. The Sportdog Field Training 425x e-collar is among the best modes the market has to offer. It’s easy to use and effective in different breeds and sizes.

Training collars have a bad reputation, but SportDog Field Trainer is entirely safe to use at any time. It doesn’t hurt your pup in any way and delivers great results in terms of training. On top of that, it’s waterproof and has a series of useful features.

In the article below, you’ll find all the information about this trainer that can help you decide if it’s the right thing to help you. Consider all the features and specifications before making the final decision.

For specific training collars, we recommend you check out the best dog collar guide.

The collar comes with a remote control transmitter that makes it easier to use on different pups. It’s designed to be compact and lightweight in everyone’s hands, allowing prolonged use.

It features the Dry Tek technology on both the collar and transmitter. The technology allows you to submerge both the collar and handset in a water depth of 25 feet. This is great if your pet is also a swimmer since you won’t have to worry about the trainer.

Adjustable levels

Previous models from the brand had less than ten levels and weren’t as effective on stubborn breeds. The transmitter’s dial allows you to select one of the static stimulation levels in medium or low ranges.

You can also opt for momentary or continuous stimulation, depending on how stubborn your pet is. There’s an option of using vibration and tone as well.

Safety and Responsibility

There’s no risk of electric shocks since the collar and transmitter are waterproof and can even be submerged in water. This allows you to train the pup in the rain as well as snow.

Static stimulation it works with is safe and doesn’t hurt your dog.

This one fits pups that weight at least 8 pounds or larger. The animal should have a neck size between 5” and 22” for most comfortable and effective use.

It’s adjustable, so you can customize the sizing a little depending on how big or small your pet is. You should make sure it fits perfectly since only then it can be comfortable and efficient.

It shouldn’t be too tight on your dog’s neck. Improper adjustment can cause irritation, itching, hurting, and all kinds of different discomfort.


Temperament of Dog

It’s especially useful on stubborn and ill-behaved pups since it offers as many different levels of stimulation. Each level is slightly stronger than the last one, so you can work around to find which one is the most effective on your dog.

Keep in mind that even the highest levels that are meant for stubborn dogs are safe to use.

Range of Effectiveness

Both components are highly effective in that range. What’s even better is that you can use one transmitter to train up to three dogs if you purchase additional Add-A-Dog collars.

Staying within range ensures the effectiveness of both the remote and the collar.

Reliability comes in the form of low battery indicators featured on both the collar receiver and remote transmitter. For some added convenience, you can charge them both at the same time using the split-end charger included in the package.

It’s a durable product that won’t break after a few uses. It handles rough weather and is equally as reliable in the rain as it is in the sunny weather.

SportDog Field Training 425X is designed to be compact and easy to use. All its buttons and controls are easy to use at any time since they’re ergonomically designed.

The set comes in black color only so the collar looks like a plain collar and not a training one. The remote is non-slippery and has simple controls you won’t struggle to learn.

It’s compact and lightweight, so you can easily travel with it if you want to train your dog while on vacation.

You’ll have to provide the proof of purchase to the brand’s Customer Care Center before honoring the warranty. A one-year limited warranty covers the product though you have to register it within the first thirty days of purchase.

Warranty doesn’t cover damages caused by animals, misuse, abuse, neglect, different events, and situations. Improper use and storage, as well as attempted repair by unauthorized service, are also not covered by the manufacturer.


Final Thoughts

It’s among the best models for more stubborn dogs that don’t do as well in regular training. Though it features as many stimulation levels, it’s advised you start slow until the animal is used to the particular level. Only then should you level up as you proceed with training.

The product is proven safe to use, but make sure to keep an eye on how your dog behaves and reacts to be sure of its wellbeing.
