I bought a decent pair of binoculars on an auction website that happened to have a reticle built-in. The pair was a Zeiss 8×30 B/GA IF Safari Roof prism. At the time, I was unaware of what reticles were. I was just attracted to the olive green rubber armor coating on the body.

That was the first time I looked through binoculars with a reticle. At first, I was a little bothered by the scale in the field of view. After a while, however, I found it enjoyable to measure the distance of objects with this pair.

Only a few models have reticles because they are designed for business and military use, such as marine surveillance. Here, I’ll explain what a rangefinder reticle is and how to use it.

## How do you measure distance or height with binoculars?

A reticle is built into the eyepiece in order to calculate the distance to an object. It also enables us to calculate the height.

Looking through binoculars with a rangefinder reticle, you’ll see scales in your view.

### If you know the height or length of an object, you can calculate the distance.

For example, there is a lion in the field (see above). If you know that the height of the lion is 1.5 meters, the distance between you and the lion can be calculated as follows:

Don’t just stand there calculating; run away!!!

### If you know the distance between you and an object, you can calculate the height or length.

If you know that a lion is 50 meters away, the height of the lion can be calculated as follows:

**What is a rangefinder reticle used for?**

Reticle rangefinders once played an important role in military and marine use. Now that laser rangefinders have become affordable and more accurate, reticle rangefinders are not used as often.

I sometimes miss my binoculars that had a reticle. It was a lot of fun calculating the height of a man working in a field. When he got closer to me after finishing his work, I would be surprised to see that he was the height I had anticipated.
