FIELD LENS : PRACTICAL, ESSENTIAL - STOCK NO. GP-FG-019
The FIELD LENS is one of those items that when we speak about essential, we mean it! Though often times overlooked, a simple Fresnel lens used properly can serve many purposes and takes up such minimal space, it is almost like it is not even there.
Fire starting with the FIELD LENS can be a bit tricky, but when mastered and on a sunny day, one can save a lot calories holding this lens rather than rubbing sticks together or using precious matches. Using the FIELD LENS as a magnifier comes in handy with First-Aid, splinters, ticks, identification and small print.
