New Scope Automatically Matches Magnification to Target Range

Imagine a riflescope that could sense target distance and shift from wide field-of-view/low magnification for closer shots to higher magnification for longer-range shots. Just think of the benefits for a hunter. He could just place his cross-hairs on a buck and the scope would automatically zoom to the optimal magnification. Does this sound like science fiction?

Darpa Lockheed DInGo projectWell the Defense Advanced Research Projects Agency (DARPA) is betting millions of tax dollars that an auto-adjusting rifle scope will soon be science FACT. DARPA recently awarded Lockheed Martin a $3.93 contract to develop a “next generation” Dynamic Image Gunsight Optic, aka DInGO. The DInGO scope automatically calculates the range with a low power laser rangefinder, digitally zooms in on it and accounts for environmental conditions such as wind using sensors built into the scope. It then projects the bullet’s point-of-impact calculated from the embedded ballistics computer. DInGO is based on Lockheed Martin’s One Shot Advanced Sighting System, which utilizes similar technology to automatically transmit crosswind information to a sniper’s scope and move the crosshairs to show the corrected point of aim.

“Current scopes are optimized for a single target range, impacting soldiers’ effectiveness and survivability when engaging targets at different distances,” said Dan Schultz, vice president and general manager of Lockheed Martin’s Mission Systems & Sensors Ship & Aviation Systems business. “DInGO will solve this problem, significantly increasing soldiers’ ability to rapidly reconfigure optics for use from short to long ranges and improving marksmanship capabilities for all soldiers.”

While DInGo scope technology will first be implemented for the military on M-4 and M-16 rifles, eventually this automatic ranging/zooming system could be adapted to hunting rifles. Such a system would be great for game hunters. When the prey appears at close range, the scope would provide a relatively low magnification level for enhanced field of view. If the animal was much farther away, the scope would autmatically increase magnification to allow more precise aiming. Hopefully this will be one example of military technology “trickling down” to the general public for sporting use.

Other Scopes with Built-In Laser Rangefinders
Both Burris and Zeiss currently offer hunting scopes with integrated laser-rangefinders that calculate holdover, based on target distance. The Burris Eliminator even projects the calculated aiming (hold) point as a red dot on the vertical crosshair. Shown below is the view through the lens of the Burris Eliminator scope, with the red dot showing holding point. Just place the red dot on the center of the target and pull the trigger. However, neither the Burris nor Zeiss rangefinding scopes automatically adjust magnification/field of view. Zooming in or out must still be done manually. That’s where the DInGO system offers something radically new.

Reading the Wind — Tips from USAMU Coach Praslick

We know many of our readers will be headed off to Camp Perry, Ohio for the NRA National Rifle Championships soon. To succeed at Perry, given the high level of competition, you’ll need solid wind-reading abilities. We’ve found an article by Sgt. 1st Class Emil Praslick III, USAMU Service Rifle coach, that can help you make better wind calls in competition.

SFC Praslick is considered one of the best wind gurus in the United States, if not the world. He has authored an excellent two-part article on wind reading that is available on the CMP (Civilian Marksmanship Program) website. Both articles contain helpful illustrations, and are “must-read” resources for any long-range shooter–not just Service Rifle and Highpower competitors.

Reading the Wind (Part One) | Reading the Wind (Part Two)

Part One covers basic principles, tactics, and strategies, with a focus on the 200-yard stages. Emil writes: “There are as many dimensions to ‘wind reading’ as there are stages to High Power competition. Your tactical mindset, or philosophy, must be different for the 200 and 300 yard rapid-fire stages than it would be for the 600 yard slow-fire. In the slow-fire stages you have the ability to adjust windage from shot to shot, utilizing the location of the previous shot as an indicator. Additionally, a change to the existing conditions can be identified and adjusted for prior to shooting the next shot.”

In Part Two, Praslick provides more detailed explanations of the key principles of wind zeros, wind reading, and the “Clock System” for determining wind values: “The Value of the wind is as important as its speed when deciding the proper windage to place on the rifle. A 10 MPH wind from ’12 o-clock’ has No Value, hence it will not effect the flight of the bullet. A 10 MPH wind from ‘3 o’clock’, however, would be classified as Full Value. Failure to correct for a Full Value wind will surely result in a less than desirable result.”

Praslick also explains how to identify and evaluate mirage:

Determine the accuracy of the mirage. Mirage is the reflection of light through layers of air that have different temperatures than the ground. These layers are blown by the wind and can be monitored to detect wind direction and speed.

Focus your scope midway between yourself and the target, this will make mirage appear more prominent. I must emphasize the importance of experience when using mirage as a wind-reading tool. The best way to become proficient in the use of mirage is to correlate its appearance to a known condition. Using this as a baseline, changes in mirage can be equated to changes in the value of the wind. Above all, you must practice this skill!
