We purchased a number of these signal whistles by ACR for use during weekend retreats with youth athletes. These whistles are well-made and very light. The large clip makes securing the whistle a breeze. This clip is a tradeoff from the traditional lanyard. While using a lanyard ensures your whistle is always in the same place and ready for use, lanyards do pose several dangers in terms of choking hazards in difficult terrain. We chose the clip approach knowing that whistles might get lost or simply fall off as student trek through trees and vegetation. The clip however proved very reliable as we have not yet lost one! The whistle is quite loud and works flawlessly even when wet. This is a must have piece of safety equipment for hiking and backpacking trips when youth will be headed off trail.
i bought this gift for my father who loves to hike so i would say it is a nice size for hikers to carry and is of a nice material that doesn't weigh so much in case u need to limit your packs weight.the price is also good for the quality of the item.
This is a great whistle, just wish it came with a clip or cord to fasten to life jacket. Nice bright color, easy to find and use. Bought for neice who just bought kayak. I have this whistle and always take it with me when I go hiking and kayaking.
