Professional BioThane® Tracking Line
Description
Heavy-Duty BioThane® Tracking Line Built for Serious Work
When reliability matters most, every detail counts.
The Professional Tracking Line is our strongest long line, built specifically for handlers who demand dependable performance during tracking, trailing, scent work, and advanced training. Constructed from rugged 3/4" Super Heavy BioThane, it delivers exceptional durability, a substantial feel in hand, and the confidence to perform in demanding environments.
Unlike traditional long lines, the Professional Tracking Line is intentionally built without a handle, reducing the risk of snagging on brush, roots, fences, or other obstacles while your dog works. For handlers who prefer a handle, one can be added as an optional upgrade.
Designed for professionals. Built to last.
Beyond the Donation
Every Bolder K9 purchase supports our Beyond the Donation program, where we go beyond traditional giving by combining financial support with hands-on volunteer work for dogs and their people.
Purpose-Built for Tracking
Every feature of the Professional Tracking Line serves a purpose.
Ideal for:
- Tracking and trailing
- Scent detection training
- Search and Rescue training
- Advanced obedience
- Recall training
- Working dog applications
The handle-free design allows the line to move smoothly across varied terrain without unnecessary snags, giving your dog the freedom to work while keeping you connected.
For handlers who want the versatility of a traditional long line, an optional handle can be added before checkout.
Super Heavy BioThane Construction
Built from 3/4" Super Heavy BioThane, this line offers increased weight and durability compared to our standard Beta BioThane long lines.
Benefits include:
- Waterproof construction
- Odor-resistant material
- Easy to clean
- Flexible in wet and cold conditions
- Excellent abrasion resistance
- Designed for years of demanding outdoor use
Whether you're working through tall grass, dense woods, muddy fields, or rough terrain, Super Heavy BioThane is built to handle repeated use without absorbing water or odors.
Our Strongest Long Line
Strength isn't just about the material—it's about how everything comes together.
Every Professional Tracking Line is assembled using TEX 135 bonded thread, an industrial-grade thread chosen for its exceptional strength and durability.
To further protect the highest-wear areas, every stitched connection is wrapped in durable PVC, shielding the stitching from abrasion, moisture, and everyday wear.
The result is our strongest and most durable long line, built for years of reliable service in demanding conditions.
Premium Hardware
Every Professional Tracking Line features:
- Heavy-duty clasps
- TEX 135 bonded thread at connections
- Protective PVC-wrap over stitches
We recommend using solid brass or stainless steel hardware for its corrosion resistance, long-term reliability, and proven performance in outdoor environments. Carabiners and frog clips are close options if you are looking for a lighter weight long line.
Designed for Demanding Conditions
Tracking doesn't happen on clean sidewalks.
Your equipment should be ready for mud, water, brush, rocks, and everything in between.
The Professional Tracking Line is designed to wipe clean after every session while maintaining the flexibility and handling characteristics that make BioThane a favorite among professional handlers.
Less time cleaning gear.
More time working dogs.
Optional Handle Upgrade
Traditional tracking lines are typically built without handles to prevent them from catching on obstacles while the dog works.
If you'd like the versatility of a handle for everyday training or hiking, you can add one as an optional upgrade before checkout.
Choose the configuration that best fits how you train.
Built for Working Dogs—and the People Behind Them
Whether you're training a young prospect, running tracking exercises, working Search & Rescue, or spending weekends on scent trails, the Professional Tracking Line is built to be a dependable part of your kit.
It's not designed to be flashy.
It's designed to work.
From premium materials to reinforced construction, every detail reflects the same philosophy that guides all Bolder K9 gear: build it once, build it right, and build it to last.

Frequently Asked Questions
Everything you need to know about our handmade BioThane® gear, production timelines, shipping, care, sizing, and custom orders.
How do I care for my BioThane® gear? +
BioThane® is waterproof, odor-resistant, and easy to maintain. Most dirt wipes off with warm water and mild soap. For heavier messes, soak in diluted oxiclean (unscented), then rinse and dry thoroughly. We recommend avoiding prolonged exposure to strong DEET-based insect repellents, which may affect the coating over time.
What if my dog chews through an item? +
Our gear is designed for durability, but no product is chew-proof. Damage caused by chewing is not covered under warranty. If something happens unexpectedly, reach out — we’re always happy to review the situation and see what options may be available.
What is considered normal wear and tear? +
Normal wear includes cosmetic signs of use such as minor scuffs, scratches, fading, or coating wear on hardware over time. Black hardware may naturally show silver underneath with regular use — this is expected and cosmetic only. Wear from chewing, misuse, improper storage, or unsafe restraint is not covered.
How much is shipping and how long will my order take? +
Our production time for most orders is 2-3 weeks unless otherwise specified. Once shipped, delivery typically takes 1–5 business days depending on location. Shipping rates are calculated at checkout, with free shipping available on orders over $75. Need it sooner? We also offer expedited processing options when available.
How are your products packaged? +
Orders are packaged simply and intentionally to protect your gear while minimizing waste. We focus on practical packaging that gets your order safely to you — nothing excessive.
Do you offer returns or exchanges? +
Because most items are handmade to order, we generally do not accept returns on custom gear. If there is a sizing issue, please contact us — we’ll always do our best to help find a solution. If there is an issue with workmanship or a mistake on our end, we’ll make it right.
Can I cancel my order? +
Orders may be canceled within 24 hours of purchase. After that, production may already be underway and cancellations are no longer guaranteed.
Do you offer wholesale pricing? +
Yes. We work with select retailers, trainers, and partners who align with our brand and values. Contact us for more information about wholesale opportunities.
How do I choose the right size? +
Visit our sizing guide page to learn more about sizing. If you’re between sizes or unsure, reach out before ordering — we’re happy to help you choose the best fit for your dog.
Can BioThane® get wet? +
Yes — BioThane® is fully waterproof and made for muddy trails, rainy walks, dock diving, and everyday adventure. It won’t absorb water, hold odor, or stay soggy like traditional materials.
