The LASER Technology trupulse 200B laser rangefinder , Yellow (7005030) measures distances and comes standard with a serial Port and Bluetooth, offers in-scope data display with 7x power optics and runs on 2 AA batteries or 1 Crv3 battery. The missing line routine is incorporated into all trupulse models. The trupulse 200 Series missing line routine is a 2D measurement. Taking 2 shots to remote targets calculates the distance and inclination values between those 2 remote targets. The trupulse 200B laser rangefinder has onboard solutions that will calculate a height or clearance value of any target, under the most challenging conditions and also has built-in targeting modes for closest, farthest, continuous and filter/reflector. Having superior optics and in-scope data display, you'll always be confident you are capturing the right measurement to the correct target.

Note that it has to small cracks as seen in the photos but otherwise works well. Let me know if you have any questions.
