Introducing the Range Calculator Brass Dog Tag

"Men admire the man who can organize their wishes and thoughts in stone and wood and steel and brass." --Ralph Waldo Emerson

BERLIN, 2021-02-11 - Once the WNDSN Telemeter Dog Tag was released in brass in November 2020, the demand for a Brass Range Calculator Dog Tag was immediate. Brass, used since prehistory, is a perennial favorite. It is malleable, durable, has antimicrobial properties, and is simply beautiful to look at, all of which makes brass stand out among trendy, more modern materials and WNDSN reaches for it again and again when creating new products.

The Brass Range Calculator Dog Tag retains the classic military format, sized according to specifications and matching current U.S. Dog Tags. Weighing in at 1.13 oz (32 grams), this Brass Range Calculator Dog Tag has a satisfying heft and body as it thumps against the chest out in the field or on the range.

What the Telemeter Dog Tag is to the Telemeter, the Range Calculator Dog Tag is to the MIL/MOA Calculator. There is one important difference, the Range Calculator Dog Tag features the nomogram of its bigger sibling, allowing hassle-free calculations, done directly on the scales with the string. To recall, a user utilizes the string to connect the MIL value on the left hand side to the known dimension on the right hand side, and read the resulting distance to the target on the center scale.

And now a first, the scales on the Brass Range Calculator Dog Tag are finished with black lacquer for better visibility. However, while the brass will last forever, the lacquer will not. At some point the user will want to repaint the scales, this has already been tested and is easy to do even in the field.

Designed for professional and recreational use, the MIL/MOA Range Calculator Dog Tag allows the user to input the MIL or MOA from their scope's reticle and return the distance to the target of known dimension. This takes out the guesswork of gauging distance, enabling accurate range estimation and eliminating mental calculation errors while under stress.

"How far is my 3.5 MIL, 12 inch target again?"

The Dog Tag’s scales are unitless, which means that the user can input MIL or MOA on the left side, and for the object size, if the value is in meters, input meters on the S-scale, and read the resulting distance meters on the D-scale. If the object size is in feet, feet is input and read as feet; to convert the result from feet to yards, the value is divided by 3. If the target size is in inches, the inner, left hand S-scale is used, which is graduated as 3 feet divided in 12 inches each. Inputting inches this way, the resulting value on the right hand D-scale is in feet.

For sub-degree angular sizes (1° = 60 minutes or MOA), the Brass Range Calculator Dog Tag provides increased precision by allowing direct input and calculation in MIL (milliradian) or MOA. The Brass Range Calculator Dog Tag calculator can thus be used as a high distance/high precision companion to WNDSN Telemeters, it uses the same principles of calculating distance from angular size, only that with the Brass Range Calculator Dog Tag calculator, the sighting and measurement is not done with the naked eye on the instrument but instead, the input values come from rangefinding reticles or similar devices.

The WNDSN family of Telemeters are wallet-size distance and altitude nomographs developed in the WNDSN applied science lab. They combine a thousand years of civil engineering, surveying, navigation, and astronomy in durable, low-tech, high utility instruments that can be taken anywhere, are self-containing, and independent of external, modern technologies.

Under certain conditions or in cases where laser rangefinders tend to fail or result in errors, WNDSN Telemeters prevail and can be used as primary or "second opinion" tools, to cross-check values obtained with different means, or in austere situations when other methods fail, are unavailable or contraindicated.

The WNDSN Brass Range Calculator Dog Tag is made in Germany, its scales are laser-engraved and precision-cut into 3 mm raw, unpolished brass. The device carries the WNDSN maker's marks; scientific instructions are engraved and supplemented by a printed how-to in both English and German. An abridged manual is included as a PDF and a 400-page printed comprehensive manual is available separately at WNDSN or via bookstores.
