Review: Really Does the Job - Product arrived quite a bit ahead of schedule. I purchased the transistor and collar originally. It worked so well that I purchased a second collar and that has worked so well that I have ordered another for my 3rd dog. Holds a charge nicely. Easy to set up for 2-3 dogs. Good power, works well at a distance and continues to work well despite my dogs being in water regularly. Excellent product. Review: works great. - I was hesitant to try a training collar at first, but this one has really made a difference for my dog. The design is sturdy but comfortable, and it comes with multiple settings so you can adjust the correction level to what works best for your pup. I really appreciate that it has a vibration and tone option in addition to static, so I can train effectively without overusing correction. After just a few days of consistent use, I noticed a huge improvement in leash pulling and recall. My dog responds quickly now, and our walks are so much more enjoyable. The battery life is great, and the remote is easy to use even with one hand. Overall, I’d definitely recommend this collar to anyone looking for a safe and effective training tool. It requires consistency and patience, but when used properly, it’s a game-changer. ## Features - Collar Receiver only; expand your current system or replace an old collar - Compatible with the SportDOG Brand FieldTrainer 425X (SD-425X), 425 (SD-425), SportTrainer 575 (SD-575E), 875 (SD-875E), and SportHunter 825X (SD-825X), 825 (SD-825) - Waterproof and submersible to 25 feet using DryTek technology - Fits dogs 8 pounds or larger with neck sizes 5"-22" - Rechargeable lithium-ion battery with 2-hour quick charge; features a low battery indicator to let you know when to charge - Detailed operating guide and a locally based Customer Care Center, reachable at 844-209-4636, provide support when you need it ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X9TZ4L3 | | Age Range Description | All Life Stages | | Animal Collar Type | Electronic Training Collar | | Brand | SportDOG | | Brand Name | SportDOG | | Breed Recommendation | All Breed Sizes | | Breed recommendation | All Breed Sizes | | Closure Type | Buckle | | Closure type | Buckle | | Color | Orange | | Colour | Orange | | Customer Reviews | 4.6 out of 5 stars 965 Reviews | | Dog Breed Size | Large | | Included Components | charging adaptor, long contact points, operating guide, receiver collar | | Item Type Name | Remote Trainer | | Item Weight | 318 g | | Manufacturer | Radio Systems Corporation | | Manufacturer Part Number | SDR-AXF | | Material | Nylon | | Material Type | Nylon | | Model Number | SDR-AXF | | Number of Items | 1 | | Pattern | Solid | | Pet Type | Dog | | Product Style | New X-Series | | Target Species | Dog | | UPC | 729849166103 | | Unit Count | 1.0 Count | ## Product Details - **Pattern:** Solid - **Colour:** Orange - **Material:** Nylon - **Brand:** SportDOG - **Closure type:** Buckle ## Images ![Brand FieldTrainer 425X/SportHunter 825 Shock Collar - Additional, Replacement, or Extra Collar for Your Remote Trainer - Waterproof and Rechargeable with Tone, Vibration, and Shock - Image 1](https://m.media-amazon.com/images/I/61VJiQHm1GL.jpg) ## Questions & Answers **Q: When should I introduce the e-collar in training?** A: Introduce the e-collar after manually teaching your dog the command on a leash first. The e-collar is meant to reinforce commands, not to teach them from scratch. Our included training manual will walk you through this step by step. **Q: At what age can I introduce the e-collar to my puppy?** A: Training with the e-collar can start when your puppy shows they reliably understand commands but is choosing to not listen. This varies, but typically happens around six months. Keep sessions short and fun, always ending on a positive note. **Q: Are e- collars safe for my dog?** A: Yes, when used properly, the static setting on a quality e-collar is a safe and effective way to reinforce commands. It's comparable to feeling a static shock after rubbing your socks on carpet. Most people can barely feel the lower levels. **Q: What level should I use to train my dog with?** A: It’s important to use the lowest effective level when training. Your dog should never jump or vocalize. Look for a slight head turn or ear twitch to know your dog feels the correction. This level will vary depending on the level of distraction. **Q: Can I change the settings on the FieldTrainer 425X?** A: Out of box, this system will deliver tone when the dial is on V/T & low, medium, and high levels of static for each number on the dial. The button functions can be easily adjusted if you’d prefer to train with vibrate or need to train multiple dogs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really Does the Job *by A***J on 20 May 2020* Product arrived quite a bit ahead of schedule.

Very humane... no perpetual tugging on leash. You may have to zap your dogs once or twice while training them, but after that a simple beep (The zap level/ beep is selectable) will do the trick. I liked them so much I bought one for each of my 5 big dogs. Note: buy the 3/4 mile range version or longer, especially for big dogs ## Frequently Bought Together - SportDOG Brand FieldTrainer 425X/SportHunter 825 Add-A-Dog Collar, Remote Training Collar, Hunting Dog Collar - Waterproof and Rechargeable with Tone, Vibration, and Shock (Orange) - SportDOG Brand SportHunter 825X Dog Training Static Collar with Remote, 1/2 Mile Range Waterproof Dog E-Collar, Submersible up to 25 Ft, Rechargeable Training Device with Static, Vibrate and Tone - SportDOG Brand FieldTrainer 425XS Remote Training Dog Collar, E Collar For Stubborn Dogs - Waterproof, Submersible Up To 25 Feet, Rechargeable Dog Training Device with Remote Static, Vibrate, and Tone --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/310367317-brand-fieldtrainer-425x-sporthunter-825-shock-collar-additional-replacement-extra](https://www.desertcart.sc/products/310367317-brand-fieldtrainer-425x-sporthunter-825-shock-collar-additional-replacement-extra) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-27*
