Designed to the same exacting specifications as the Red BP-1 Trajectory Laser, the new green laser is more visible to the eye in daylight conditions. As with all EVI-PAQ® trajectory equipment, the BP-2 is co-aligned with it’s case for consistent accuracy during trajectory reconstructions. The laser is powered by two standard AA batteries and is compatible with all EVI-PAQ® trajectory rods and accessories.
