"TAS is an easy to use aid to precision shooting. We at TAS have employed decades' old ballistic technology and coupled it with innovative calculations, 'Real World' Data and  modern materials to make TAS,  easily,  the simplest,  most accurate ballistic aid you will have used yet. In developing TAS we have sought the advice of some of the top shooting professionals in the Hunting field, as well as Competition, and Field Target shooters. Coupled with hours of test firing, data compilation and calculation the result is a, no nonsense, robust unit, suitable for almost any rifle shooter or marksman's needs". Dougie Lorimer - TAS Designer.

The TAS is the result of many years' effort to produce a simple, easy to use system for rifle shooters that could guarantee accuracy with each and every round. Make no mistake about it - the TAS is almost 'awe inspiring' in its accuracy - across all rifle calibers up to and including .50 cal bmg and the increasingly utilised, .338. All this is achieved by TAS and  NO Batteries, NO Electronics and NO Software !

TAS is available in Civilian, Police and Military Models. The rugged polycarbonate construction means that TAS is well suited to the military role. Electronic Units are great on the military camp firing line where they are not subjected to the testing environments of operational theatres, but can you afford malfunctions at "mission critical" moments?

Competition and Law Enforcement shooters also need the high level of reliability and accuracy always available from the TAS System. Short of being physically destroyed, the TAS will continue to provide accurate shot solutions whenever, and wherever, you need them. All this comes with a low unit cost and a lifetime guarantee. That's how confident we are about the durability of TAS, even under the most severe and testing conditions. TAS means 'Reliability and Accuracy' without electronic 'gizmos and gadgetry'!
