Herm Sprenger Zoom ULTRA-PLUS Training Collar with Center Plate, Assembly Chain, and Swivel Ring - Stainless Steel BlackZoom ULTRA-PLUS Training Collar with Center Plate, Assembly Chain, and Swivel Ring - 3.2mm Black

When it comes to communication and control, nothing beats a properly fitted prong collar used by a skilled handler—and Herm Sprenger sets the industry standard. The Ultra-Plus 3.2mm model is our go-to for dogs up to 88 lbs, offering balanced correction without overcorrection when used with purpose and clarity.

Made from high-grade stainless steel, this collar is built to last and won’t rust, discolor, or fail in the field. The buckle closure makes for fast, secure on/off handling, especially in dynamic training environments. No fiddling. No wasted time.

The swivel attachment adds another layer of performance by preventing leash tangles and allowing natural movement between dog and handler—critical for fluid motion during obedience, off-leash drills, or high-pressure scenarios.

At 3.2mm, this collar fits necks up to 19 inches and is ideal for medium to large working breeds. Need more length? Add individual links as needed—fit is everything when working with a prong.

This is not a punishment tool. It’s a communication device, and when used correctly, it builds clarity, trust, and real behavioral change.

Used by law enforcement, military K9 teams, and professional trainers worldwide—and proudly trusted by American Standard Dog Training.

Train fair. Train firm. Train the standard.
