    This is a great product. I will have to remember to look for this information format. I sometimes glaze over bracelets as jewelry ( I use that term loosely but with respect).

    If you want an EMS provider to thank you. Provide these five lines of information...
    Name (First, MI, Last)
    D.O.B. (mm/dd/yyyy)
    A = Allergies
    M = Medications
    P = Pertinent medical history

    If your feeling daring, your Social Security # would be the Cherry on top of this Sundae.

    Another set of very good info is I.C.E.=I.n C.ase of E.mergency
    your I.C.E. phone list should be organized by those of your family who have the best knowlege of you and your medical conditions first

    if you're on a budget then a 3x5 index or recipe cardwith the above information then laminate it like a standard players ID badge

    Good try, you just need to do a little research

    Here's an interesting take on it that I just came up with...

    For a regular arc shot (assume for simplicity that the ball isn't spinning at all) the velocity that is lost during the first half of the arc due to gravity will be regained during the second half of the arc - again due to gravity. The ball will still be going slower than when it left the marker, but only thanks to the air drag as it travels.

    Actually tests have been done in ballistics. These tests and experiments show that aerodynamic drag exerts more force on a projectile than gravity. In the absence of air drag the calculated distance of one projectile with the presence of gravity was 47 miles. With air drag the range is only 2 miles.

    For a flatline shot let's assume (again for simplicity) that there is no arc at all. This is achieved thanks to the ball's spin. Thus, as for the first ball, the only velocity loss is due to air drag.

    But here's the kicker - if we assume equidistant targets, the flatline ball is taking a shorter path to the target, and should thus lose less velocity to air drag in the process. By this logic, the flatline ball is actually hitting the target at a higher velocity!


    And here's WHY (by my spur-of-the-moment reasoning):
    The regular arc shot relies on the ball's linear momentum to overcome gravity and air drag. The flatline shot requires the ball's linear momentum to overcome air drag only; it's the ball's rotational momentum that overcomes gravity.

    Actually, the flatline uses the spin to harness the drag in a contructive manner. This is called the "Magnus effect". Here is a wikipedia link to show you how this works....

    http://en.wikipedia....i/Magnus_effect

    The drag is still active on slowing the ball down but the lift generated helps it fly "flat".

    IMO There is no true range advantage to the flatline. Once aerodynamic drag has absorbed the forward energy the ball simply drops. Those who are not aware of basic ballistic concepts and arcs are alowed to "Point and Shoot".

    The Flatline/apex does allow you to shoot "under" the canopy be it the roof of a building or low branches of trees. Non-flatline barrels allow you to "drop" paint on people behind bunkers at range. This is on of Tyger's classic "thread the needle" tricks as seen on earlier episodes of WDR.

    In each case all of the paintball's kinetic energy is supplied by the marker's CO2/N2. But if both markers are chrono'd to the same muzzle velocity, the flatline ball is carrying more energy than the regular ball - in the form of rotational kinetic energy - which the chrono doesn't read!


    I'm actually a bit taken aback by this line of thought. But it seems sound to me. :P
    A test must be undertaken!!!


    Good try at reasoning this information out. You just needed to do a little more research.

    Already made several similar to master mines. Goto http://www.milsimemp...c.php?f=36&t=45 Slight variation on the trigger. I have gone two generations of evolution on the trigger and nozzle setup. I need to post up the new plans

    Yes, Smakzone is a great loss to those of us in the scenario/big game community who saw it as a wonderfull escape. The announcement is less than three days old and most of us are still getting over the suddeness of the closure. I was actually getting my 9 year old son prepared to celebrate his 10th birthday by taking him to Smakzone's annual "Operation Eminent Storm"

    Woodsball teams in the area are Team Blackout, S.O.G.7, & St Louis Samurai.

    I myself, live in the western part of suburban St. Louis. Fields that may work for you are Fearless Fighters and Bushwhackers paintball both are in Pacific.

    South of your general location is Crowley Ridge Paintball and Runaway paintball.

    Hmmm, Pick up a digital scale with that and I might be a happy camper. (+$100 to cost of next rifle setup)


    The mechanical scale that comes with the kit is more than accurate enough. Just zero the scale every session. I get accuracy so good that if I don't hit a quarter at 100yds, it's operational error not reload error.
