Herm Sprenger's latest innovation to the prong training collar. The Neck-Tech design features a stainless steel collar with each part stamped from solid coiled stock. This unique design imitates canine teeth and allows the collar to have a more natural "bite" during the correction pull. The links of the Neck-Tech are called "elements" and offer a more comfortable fit than the traditional prong collar. This collar is available in different styles: Traditional Martingale type with quick release bolt snap and the nylon style with a safety buckle. Both styles are available in two lengths, 19" and 24". Elements may be added or removed for proper fit.
