As opposed to the BCB signal mirror (which has a shiny metallic finish) the Coghlan’s model has a glass reflection surface which is far superior when it comes to producing a strong flash of light. Metallic type finishes will soon lose their lustre, which dramatically reduces the brightness of flashes. Glass on the other hand, will provide you with much stronger and more powerful flashes for a very long time.
Although the Coghlan’s model is slightly larger, it’s by no means big and no less portable. It can easily slip into your pocket and is ultra-light. Additionally, the larger size of the Coghlan’s signal mirror is noticeably more ergonomic (making it easier to maneuver and less susceptible to dropping) and catches more light. The larger sighting hole also makes focusing and aiming less strenuous and less tedious.
The plastic sleeve it comes in can be reused and has a tab that can be tucked in, helping to protect the device from scratches. Because this signal mirror is literally a mirror, it can be used as such – something that is not really possible with the BCB model once it loses its reflective qualities. One similarity both models share are instructions on the back – a very handy feature.
- Glass reflection surface for superior flash distance

Super thin, ultra lightweight and very small – you’ll barely notice you’re carrying it.
A signal mirror is an essential piece of survival gear. This particular model is issued to the British army and can be aimed very accurately at a target.
In a survival situation, do not underestimate the functionality and effectiveness of this device to attract attention. A flash from a heliograph can be seen from a tremendous distance. Not only does the BCB signal mirror give off super intense flashes, but it also has instructions stuck on the back in case you forget how to use it.
