Review on Jucoan Emergency Survival Whistles Keychain by Bryan Aleman

Our group goes fishing abroad twice a year. When we leave a river/lake, sometimes we separate from the others. Three of us have health problems and sometimes struggle to keep up with the others. The distance from vehicles to the 'fishing holes' is less than a mile, but at the end of the day it can be a bit difficult. If one of us gets stopped or injured on the trail, we can now use one of the whistle to signal for help. We have whistles hanging from individual chains on a hook just outside the cabin door. At the exit, everyone takes one and hangs it around our necks. The whistle is unique. So when she's heard, we know she's one of us.
