Rangefinder
Upgrades (Weapon Upgrades)
Any ranged weapon can have a rangefinder built into it. Such a weapon takes no penalty when used to attack a target at short range. Thus, a blaster pistol with a rangefinder upgrade takes no range penalty on attacks against targets up to 40 squares away.
This is essentially an improved version of a targeting scope, and thus its benefits do not stack with those of targeting scopes. (However, a weapon can have both a rangefinder and a targeting scope, using the latter only when aiming at targets at medium or long range.)
