This Mini UV Led Torch is a great way of getting those special caches that require a Ultra Violet Torch.  It is small, very compact, easy to use as you can either hold the centre between two fingers, or slide the button to keep the torch switched on.  They are long lasting as the single LED does not use much power but provides a powerful light.  And it can easily be attached to your keys or geocaching equipment so it is on hand for when you need it.

The torch measures approximately 4cm x 2.3cm x 1cm (not including the attached split ring)
