[New Release! Dual Ultrasonic Ports & Wideband Frequency Added] This is a 100% safe ultrasonic handheld dog bark control training device compatible with all dog breeds. This product is equipped with two ultrasonic transmission ports, making it the most powerful and versatile on the market. While 25kHz ultrasound is effective for most dogs, about 10% of dogs that are difficult to train tend to ignore this sound over time. Therefore, based on research on canine hearing, we have added a rapid fluctuation pattern of waves between 23kHz and 30kHz to prevent the dog's auditory system (and brain) from blocking the sound. This is expected to improve various problem behaviors such as excessive barking, biting, destructive behavior, digging, chasing, running away, and even ingesting dangerous objects.
[3 Operation Modes Switchable / Ultrasonic Intensity Level Adjustment] You can choose from three modes: Ultrasonic mode (1-3 intensity levels adjustable / switchable with L button), Ultrasonic + Flashlight simultaneous operation mode (combined effect of ultrasound + strong vibration + flashing light), and Flashlight only mode. Remote control is possible up to 15m. It can immediately address a variety of problem behaviors such as biting, digging, aggressive behavior, and chasing behavior, and the optimal intensity (Level 1: Low to Level 3: High) can be set according to the dog breed and training purpose.
[2 Types of LED Light Modes / Stray Dog Countermeasure / Night Walking] The flashing mode uses powerful ultrasound and flashes to intimidate and deter aggressive behavior (chasing, biting, etc.) of stray dogs, while the steady light mode can be used as a safety light during night walks. This product prevents stray dogs from approaching by instilling fear through simultaneous emission of ultrasound and flashes, ensuring the safety of owners and their beloved dogs. It also has a multi-functional design that can be used as a backup light in emergencies.
[Type-C Fast Charging Compatible / Battery Overvoltage Protection Function] Built-in 650mAh high-capacity lithium battery, with an overvoltage protection circuit to prevent damage during charging, and a real-time battery level display function to prevent sudden power loss. Full charge is possible in about 2-3 hours with Type-C port fast charging.
[Lightweight and Compact Design / Accidental Operation Prevention Function] Features a smooth texture in a lightweight body weighing only 86.5g.
