About this item

- Precision Adjustable Ultrasonic Frequency: Tunable frequency range of 20kHz-28kHz, perfectly matching the hearing range of canines (15kHz-50kHz) while remaining silent to human ears (hearing range 20Hz-20kHz). Rotate the tuning screw to lock the optimal pitch for your dog, ensuring consistent signal transmission and avoiding ineffective training due to frequency deviation.
- Multi-Scenario Professional Training: Engineered for professional dog training scenarios—recall training (even at long distances up to 100 yards), excessive barking correction, obedience training (sit, stay, heel, come), and behavior shaping. Suitable for indoor training, outdoor activities (hiking, hunting, agility training), and noisy environments (parks, streets) with stable sound transmission.
- Food-Grade 304 Stainless Steel Construction: Adopts high-quality 304 stainless steel, non-toxic, corrosion-resistant, and impact-resistant. Weatherproof design withstands extreme temperatures (-20℃ to 60℃), rain, and humidity, ensuring long-term durability for outdoor and daily use. Smooth surface without burrs, safe for both dog and owner.
- Ergonomic & Battery-Free Design: Compact ergonomic structure (2.8 x 0.7 inches, 0.6 oz) fits comfortably in hand or pocket; equipped with a detachable stainless steel lanyard for hands-free carrying and quick access. No batteries or charging required—manual air-blow design ensures instant use, with consistent sound output even with light blowing, suitable for professional trainers and beginner pet owners.
- Humane & Scientific Training: No harsh sound, no electric shock, no chemical stimulation—relies on ultrasonic signals to guide dog behavior, protecting your dog’s hearing while achieving effective training. Suitable for all dog breeds and ages, from puppies (3 months+) to adult dogs, including small, medium, and large breeds.
