Double-Alpha EDGE Shot Timer

The Double-Alpha EDGE Shot Timer is the result of several years of market research, engineering, and field testing. It has been designed to set a new benchmark in Shot Timer performance — optimized not only for individual shooters, but also for Range Officers and professional trainers.

Built to the highest standards, the Double-Alpha EDGE features a fiber-reinforced polymer housing, large tactile control buttons, a thick gorilla glass display protector, and full IP65-rated sealing. This robust construction ensures long-term reliability and consistent performance, even under demanding range and environmental conditions.

Performance and Design

The Double-Alpha EDGE incorporates a range of industry-leading technologies that distinguish it from all other Shot Timers. Its advanced shot detection algorithms and adaptive echo filtering enable precise performance tuning for any shooting environment. The wide microphone sensitivity range allows for flawless operation across a full spectrum of applications — from airsoft training to high-caliber rifle and pistol indoor shooting.

Power and Operation

The unit is powered by two CR123A batteries (not included), providing 25–50 hours of operation, depending on usage conditions. Power consumption increases with extensive use of the display backlight, flashlight, illuminated buttons, or wireless connectivity. The Double-Alpha EDGE is fully compatible with rechargeable CR123A batteries (ensure they are approx 34.5mm in length as some are longer), which are readily available through major retailers such as Amazon.
