• 【Affordable Set】Given the high demand for electronic whistles from referees, coaches, teachers, and staff, we've introduced a 4-pack of electric whistles to offer a more affordable option. The set includes four colors – black, red, along with new additions of gray and army green – making it easier to distinguish between them.
• 【Hygiene & Safety】The handheld electronic whistle replaces the traditional mouth-blown whistle, eliminating mouth contact. Simply press a button to produce a loud, clear, sharp, and easily recognizable sound. It’s a more hygienic and convenient option for all sports events, corporate activities, school competitions, or other training sessions.
• 【Adjustable Whistle with 3 Tones】Are you tired of traditional whistles not being loud enough? The electronic whistle for coaches produces a powerful 120±5dB sound and offers three different pitch options, allowing you to choose the perfect tone for any situation.
• 【Durable & High-Quality】The electronic emergency whistle is made from high-quality ABS material, giving it excellent shock resistance, making it ideal for outdoor use. It is also powered by 4 CR2032 lithium batteries, ensuring long-lasting performance in the field. If the sound becomes faint or unusual, please replace the batteries.
• 【Easy to Use & Portable】The electronic whistles for referees is perfectly sized at 5.4" × 1.5", making it easy to fit in your pocket or backpack. It also comes with a 46-inch lanyard, making it convenient to hang on your backpack or wear around your wrist or neck. Ideal for taking anywhere you go.
