The VSP took delivery of some Mk III units last year.

The first production Mk IV and Mk IV+ units arrived in the States on Sept. 20 and I tested both for the manufacturer beginning Oct. 1. Three weeks later I tested a third unit, with revised software to catch Whistler's new platform shared by the Pro 78 and XTR 690. That one served as the first in the Mk IV+ series, a number of which are earmarked for the VSP this year.
