About this item 1、Ultra-strong penetration with 120dB dual-pipe. The dual-chamber structure achieves high-frequency resonance, a sound volume of up to 121 decibels. The sound wave penetrates complex environments such as wind and rain, jungles, etc., ensuring that rescue signal is effectively conveyed. The non-ball bearing design eliminates the risk of blockage, improving airflow efficiency and reaching the peak volume immediately. 2、No moving parts+ frost-resistant design The design uses a seamless one-piece structure with no holes, no ball bearings, and no springs, thoroughly avoiding issues such as iceage, sand and mud blockage, or component damage (compared to traditional metal whistles that are prone to ice build-up and lip stickiness). The high- ABS material is resistant to a temperature difference of -30℃ to 71℃, and can be used normally in rainy, falling into the water, and dusty environments. 4、Ergonomically lightweight, safe and portable, non-stick lips The design conforms to the curve of the hand for a comfortable grip, and the ABS material does not stick to the skin in cold environments, avoiding the risk of frostbite from metal whistles. 5、Reflective suspension system, quick access design for scenarios The standard adjustable reflective rope dual-mode buckle, the slide buckle adjusts the length of the neck cord (suitable for children/adults) the stainless steel clip buckle can be quickly hung on a backpack, life jacket, waist belt, etc. The reflective strip enhances visibility at night, allowing for quick positioning in dark. 6、Full coverage of outdoor scenarios The high-density ABS shell is impact-resistant and corrosion-resistant, surpassing the rust-proof limitations of metalles. Suitable for: water sports (sailing/paddleboarding/canoeing), land exploration (camping/hiking/hunting), emergency rescuefirefighting/earthquakes), and pet training.
