Downloadable Data
Downloading data is as simple as pressing the F2 key. The run can then be graphed in any combination of speed, time, distance, and acceleration.
Performance Stats
Statistics can be selected from a list, or customer measurement points can be created using simple start and end settings. STATS II provides performance information anywhere on a run, not just ending times.
Reduce Confounding Variables
A new file can be created by averaging several runs together. This is great for reducing the effects of variables like the wind.
Built-In Help
Built-in context sensitive Help is always available at the push of a button. A complete version of the manual is stored in the help files.

It is the ultimate tool for racers and manufacturers to test and tune products for maximum performance.

Powerful, hand-held Radar With a 1 – 800 mph speed range, it’s capable of clocking automobiles for up to 1.75 miles.

Speed and acceleration events are measured at precise intervals and stored in the gun as separate trials. The number of trials that can be stored is dependent on each trial’s length. A total of 60 minutes of readings can be stored in the ATS II.

Data Transferred to Computer
To process and analyze the speed and acceleration data, the ATS II is first connected to a computer running the Stalker STATS II software. The data is transferred and saved as a file on the computer’s hard drive. Since speed, time, distance, and acceleration (or deceleration) are mathematically related, having any two of these measurements mean the other components can be derived with absolute accuracy.

Use the ATS II Anywhere
The ATS II gun is waterproof in up to two feet of water so you can use it anywhere – on the lake or ocean, on snow, on straight roads, in your car, or in your backyard. Just position the ATS II behind (or ahead of) the test vehicle. You can even place the radar inside the test vehicle and take speed readings from the terrain. There is nothing to attach to the vehicle to change its aerodynamics or weight.

Simply connect the ATS II to your computer running STATS II and download the trial data. Software analysis is simple and automated.
