Before lasers

[Hoshua1]

What are the older methods of scaling range. Before the use of lasers how did people measure yardage through binoculars/range finders. Were older binoculars or range finders built in guages? I can't help but imagine the parascope in a sub with its tick marks. I'm interested in the GPSvsCompass aspect here. I'm sure there are antique methods to scaling range with older equipment.

Experience

Don't mean to be flippant but I've been around before there were such things as lasers. Had a Red Ryder when I was five, first .22 at seven. Spent enough time on the 200 meter line when I was in the service. Worked as a surveyor, among other things. Best guesstimates, "Kentucky Windage" and a spotter with good optics works for me.

Thats what I'm getting at. I like being a good shot with iron sights. I like looking at maps rather than mapquest. I'd like to learn some of the dated techniques that were implemented by spotters.

Optical rangefinders

View attachment 265075

This is a Collimeter Rangefinder, it uses optics to determine distance. I found this at

I am not familiar with the operating system of this one but generally speaking, optical rangefinders work either with a split image - adjust focus until target images merge or they work with two separate lenses and there would be a readout on a dial to state the range to the target.

Learning to use a traditional map & compass is a really good idea. GPS is fine but it depends on satellites, and if the bird goes down or dark then you’re SOL.

The popular sport of geocaching is an offshoot of Orienteering, where you are given a topo map and a time limit to get to a series of checkpoints. Both are fun. The old skills are the best skills, and are what will get you home.

BTW if you cache supplies &/or equipment along your bug out route so you don’t have to depend on things like gas stations and stores you might want to consult some of the on-line geocaching sites. There are an awful lot of folks out in the woods looking for things these days.
