    Does anyone use systems that detect laser range finders and target markers?

    that sounds pretty spiffy, preacherman, but i find myself wondering if the researchers at the University of Maryland's Intelligent Optics Laboratory realize bullets don't travel in straight lines. I could be mistaken, but even a 50bmg is going to drop 150odd feet at that range, and be pushed about 70' off course by a 40mph wind.

    unless i've just wildly miscalculated, which is entirely possible as I'm half asleep, the bullet would peak about 51' over line of sight. at that distance, the FOV on a 25x S&B PMII is 68'.

    Google around for "wind measurement laser" and there is all sorts of interesting research going on.

    MechAg--

    If you look through a set of PVS-14's, the output beam of a laser rangefinder is visible like a laser pointer would be, on the object it hits, as well as its emitter.

    Why not use a sonic measurement? Spit out a bunch of ultrasound bat style, and measure the doppler shift on any grit that happens to be in the air to bounce back your signal. It would have a much larger field of view than a laser, and be rather less detectable.

    ok so it accounts for windage only right?

    If I had something that "accounts for windage only " I doubt I'd ever miss. Sounds handy to me. However, I am fortuinate enough that I shoot for fun and enjoy the wind.

    The Diarange has a second focal plane reticle and its knob setup is behind the curve for high-end LR riflescops. A BDC reticle has disadvantages and drawbacks, and in a SFP configuration is only usable at one magnification setting. State of the art for knob-based elevation specification looks more like S&B's USMC contract scope (which is almost identical to a PMII).

    Too slow and too easy to detect. It would take about 12 seconds from emission to reception at 2,000 meters, depending on altitude. Laser is virtually instantaneous. Also, Sonar is not as accurate in atmosphere as it is in more dense mediums, such as water.
