S.O.L. Survive Outdoors Longer Unisex's AD0010 Fixed Blade, Knife,Hunting,Outdoor, Orange, Slim Howler

I recently purchased this loud whistle to enhance safety during my outdoor adventures especially when out mountain biking. The whistles are slim, lightweight, and come in bright orange, making them highly visible and easy to carry. Their durable plastic construction and pea-less design ensure reliable performance in various weather conditions. In standard use, these whistles produce a loud, piercing sound that can be heard over considerable distances, making them ideal for emergency signaling. To test their noise output, I attached one to my drone and found that at low altitudes (20-50 feet), the whistle produced a clear, loud sound that was easily discernible over the drone’s motor noise. At higher altitudes (50-100 feet), the sound remained audible, though less intense. Moderate drone speeds yielded the best performance, while high speeds slightly reduced the effectiveness due to wind interference. Overall, the whistles performed exceptionally well, proving to be a powerful and reliable tool for outdoor enthusiasts. A whistle is a must-have for bikers, hikers, campers, and adventurers. I highly recommend this one for its robust performance and thoughtful design.

Recibí dos silbatos de la marca que esperaba. Funcionan bien. Aunque el embalaje es un poco diferente de lo que se ve en las fotos, el producto es el correcto.

Excellent product! Very compack tiny and extremlily loud. Can't wait for snowmobile season now, let it snow!

I measured it at 125 dB. That clearly puts it in the survival whistle category. It is also sturdy. Of course, if you purposely slam a heavy iron rod against it you might break it.

- Very visible bright orange color- Loud- It's so slim it can easily be stored flat in an emergency pouch or first aid kit- Very good price for a 2-pack
