Standard mode gives smooth payout for thicker ropes, while teeth-milled high-friction channels offer up to 3x holding power for extra control on thin strands or heavy falls. **Q: Can the Big Air XP be used in "guide mode" directly off an anchor?** A: No. The ATC-XP is a traditional tubular device without an auto-block release eyelet. If you need guide-mode capability for belaying seconders directly off a multi-pitch anchor, choose the ATC-Guide. **Q: Is this package suitable for double-rope rappelling?** A: Yes. The device features two slots for double-rope rappels, and the high-friction grooves allow you to easily regulate descent speed and heat dissipation across long rappels. ## Frequently Bought Together - Black Diamond Big Air ATC XP Belay Device and Rocklock Screwgate Locking Carabiner Package for Rock Climbing - BLACK DIAMOND Men's Momentum Rock Climbing Harness - BLACK DIAMOND Hotforge Screwgate Locking Carabiner 3 Pack for Rock Climbing, Mountaineering, Camping, Outdoor, --- ## 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.tw/products/25493941-big-air-xp-belay-device](https://www.desertcart.tw/products/25493941-big-air-xp-belay-device) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-22*
