Coghlan's Sight-Grid Signal Mirror
The Coghlan's Sight-Grid Signal Mirror is a great way to signal people across distances. It allows you to reflect light from the sun to create a signal that can be visible for up to 25 miles. It is a glass mirror, but it comes encased in acrylic to prevent it from breaking and to keep it afloat if dropped on water. The lightweight mirror comes designed with a sight-grid mesh that lets you direct the reflected light accurately to a certain area. Even in the hazy weather, the light from this mirror can be seen clearly. The Sight-Grid Signal Mirror is especially useful to communicate and so the rescuers will know your exact location. This is an essential tool when you're out hiking or trekking in the wilderness. So make sure you bring a Coghlan's Sight-Grid Signal Mirror when you set out for your outdoor adventure.
