3-Pack Credit Card Size Pocket Fresnel Lens - Magnifier Lenses for Fire Starting

I bought a pack of these because we like to have some emergency supplies around. We also go backpacking. I put one in both of our vehicles and I carry one as a backup fire starter for when we go backpacking. They start fire, but require strong sunlight, no cloud, directly overhead. If its not direct, untampered with sunlight, it will not work. Would recommend as a backup/emergency item, but not a primary fire starter.

Specifically bought this to use to start fires and magnify small print on pill bottles etc... This card will start a fire no problem even in Alberta in January when the sun is not the hottest. Carry one in my truck, my wallet and one for my small survival kit. Well worth it.

Delivered quickly enough. These are very thin and I haven’t been successful in starting a fire yet. As to the quality I really don’t know but they were expensive enough so I’m hoping they will be a good addition to my hiking survival kit.

This 3-pack of Fresnel lenses are a good deal for the money and a solid product for survivalist, campers, hikers, or anybody needing a last resort method of lighting a fire on a sunny day. These are thin, flexible and about the size of a credit card and will slip into a wallet or go bag without weight or taking up space. A must have in my opinion. Fresnel lenses are a magnifying lens specialized designed to ignite dry tinder and start a fire, but you must have sunlight like any magnifying glass.An important aspect of these Fresnel lenses is that they are 4x magnification compared to many that are only 2x. The 4x will burn quicker and help you get the fire started. As in any fire starting venture, you want the driest tinder possible, and build a small tinder pile (or make a tinder bundle) and focus the light beam to start the burning process. Make sure you have dry twigs and larger woods on hand to build your fire.A handy thing to carry in your go-bag is a couple dry tea bags that can help assure you of something that will ignite in a less than perfect environment.Tinder bundles are compressed dry leaves and small twigs. You don't want them to be to loose, but not to tight either, because you want air to circulate through the bundle to aid the fire. In a survival situation, if you have access to dry tinder materials, you want to make several tinder bundles while the getting is good in case it rains. If you have some plastic, wrap them up to keep them dry, or put them in an article of clothing and stash them so they won't get wet.You can see many demonstrations on You Tube.Highly recommended!

These come individually packed, great as a multi purpose tool in survival kits.The magnify for map reading, start fires, reflective for signals, straight edge for measurements and navigation.Very light and compact.
