The long awaited ballistic radar for consumer use is finally here. Labradar performance exceeds any consumer level velocity acquisition system. It continually measures velocities of your rifle, pistol, shotgun (slugs), arrows or pellets up to 100 yards depending upon the size of the bullet. Smaller bullets do not track as far as large bullets. Multiple distances for velocity display are user definable on the unit. LabRadar measures velocities up to 3,900 f.p.s. with 0.1% accuracy using six AA batteries.
