To get prepared for most SHTF situation, you would need to find the best gear and learn up appropriate skills. One of the most useful equipment would be a rangefinder, where you can choose to use it for survival, hunting or even mountaineering.
To utilize a rangefinder properly, you need to understand how it works. Laser rangefinders function by emitting laser beams which subsequently bounces off your intended target. The high-speed clock in your unit would then measure the amount of time taken for the beam to leave and go back to the unit.
Some general principles to note is that the greater the beam dispersion, the further your unit can range. However, a smaller beam divergence would give greater ranging precision despite it not being able to range far objects.
Another interesting thing to note is how the rangefinder would calculate distance. The rangefinder will employ a calculation method called ‘time of flight’ principle, calculating the speed of light.
After understanding some basic concepts, I would like to share some tips you can use for your rangefinder.
I like flashlights. A lot. My wife would say I might be obsessed,
I was going to say I’m a bit of a light snob but that would be wrong. I have cheap lights and recommend them. More accurately I’m a lumen snob. The more the better.
I have always said you can’t go wrong with more lumens.
The Nitecore NU25 Headlamp does not come up short in the lumen department at 360 max lumens. And it does this at only 0.99oz.
So let’s find out whether this needs to be your next headlamp.
