Almost certainly adds to the Minimum Scan Range property on all of the unit's weapons, the way the Range one works.
Like it says that property only works for the minimum scan range, so for instance melee attackers will engage at range 5 and not their weapon's range like ranged units.
It shouldn't let you actually reduce the scan range, only boost it.. but who knows, maybe their description sucks.

And maybe it can reduce lag with map with many units? (as weapons may search less...)
Its in buff behavior: modification->weapon.
