The Field Density Altitude Compensator (FDAC) in YARDS or METERS

The FDAC is an analog slide rule that displays elevation and windage firing solutions using density altitude (DA). It has two sides, side (A) calculates firing solutions in MOA (minutes of angle) and side (B) calculates in 0.1 MRAD (one tenth milradian, commonly referred to as “mils”). The front of the product has a density altitude calculation table, allowing the user to easily compute density altitude with acceptable accuracy in the absence of an instrument such as a kestrel or other device that measures density altitude.

The FDAC comes with (5) internal slides which can be swapped out by the user. Each slide contains ballistic data specific to the most common velocity range used with the 175 Sierra Matchking (2500,2550,2600, 2650, 2700 fps). The user simply inserts the slide which is the closest to the muzzle velocity of his rifle, and then slides the internal firing solution matrix (the slide) until the current density altitude and the below listed firing solutions are visible in the viewing window. All firing solutions contained in the FDAC are calculated using the G7 drag model.

Ranges listed on the FDAC are in Yards and are in 50 yard increments up to 800 yards. From 800-1,000 yards all range increments are listed in 25 yard increments, providing the user with a much more refined firing solution for very distant targets (greater than 800 yards).

Windage figures listed on the FDAC are based on a 5mph full value “baseline” wind, allowing the shooter to easily multiply or divide this baseline as winds increase or decrease in velocity, or the wind value (wind angle) changes from perpendicular to the axis of fire (which would be a full value wind).
The sonic barrier is marked in red on each slide to indicate at a given density altitude, target distance, and muzzle velocity the point in which the projectile will begin and maintain sub-sonic flight. This was found to be very helpful for shooters engaging long range targets in very dense air in which their projectiles would become unstable and possibly unpredictable in flight.


This product was entirely conceived, designed, and validated by Adaptive Consulting & Training Services, LLC (ACTS). ACTS is a small business completely owned and operated by former USMC Scout Snipers.

The FDAC is a great tool. It works day or night, hot or cold, rain, snow or shine.
It is light weight, fast, easy to use, and accurate in real world shooting situations, without the need for batteries!
If you do not have one, you need one!

I recently purchased one of these and it is unbelievably accurate and far easier to use than my PDA based ballistic software. Best money I've spent on shooting equipment in years.
