Coghlan’s Sight-Grid Signal Mirror

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
  • Waterproof & Break-Resistant acrylic case
  • Instructions for use on back of signal mirror
  • Lanyard hole
  • Floats
Highly recommended

  1. I’ve used both the Coghlan’s plastic-encased glass signal mirror shown here and the all-glass 2″x3″ glass Coghlan’s Model No. 9902 Survival Signal Mirror (also with Sight-Grid). While the 9902 is heavier, and more prone to break when dropped, than the plastic-encased version, I rather prefer the 9902, since the reflection seems brighter and it is less prone to scratches.

    One question I’ve been asked about the 9902 is how it holds up to Canadian winter weather – I’m told since glass can shatter in intense cold, and there was concern about delamination of the laminated glass.

    Looking at the photos on your web site, it seems it gets fairly cold up there – any thoughts or experience of the durability of the 9902 in that climate?

    • Hi Richard,

      Yes – it definitely gets extremely cold here (Winnipeg is often referred to as “Winter-peg”). The Saturday evening of the course it was -36°C without the wind!

      We’ve only ever used the BCB British Army Issue signal mirror and the plastic-encased Coghlan’s glass signal mirror (we prefer the latter). We’ve never experienced any issues with the glass mirrors shattering or delaminating in cold weather. Having said that, we usually keep them tucked into a chest pocket where they’re not only safe, but relatively warm. In winter conditions, if the mirror was dropped (and we’ve dropped them), there is usually enough snow on the ground to provide some shock absorption. Certainly a valid concern though since taking signal mirrors out of pockets in winter conditions often requires a person to remove their heavy mitts/gloves – and if you leave them off to manipulate the signal mirror, your hands will get cold and your dexterity will become weaker, increasing the chances of the mirror not only being dropped and potentially damaged, but also lost in the snow. As such, we try to handle this essential piece of kit with care at all times.

      FYI – We just added another picture of Coghlan’s signal mirror in action – check it out!

      Thanks for the question Richard – we are humbled.
