stupid question, but is the height of the cross bar measured from the bottom of the box or from the top (ground level)?

Ground level, from the center of the box (lowest point of sag).

$149.00 lord have mercy!!
At a street vault this summer, the USATF officials used a measuring device made out of PVC pipe...it couldnt have cost more than $25. I do like your designer measuring device though, but I couldn't afford it.

$150 for a measuring device isnt too bad when you compare it to the UCS one at $530!!!!!!!!!!!!!!

Also cheap compared to the laser measuring devices such as the Disto CLASSIC for a mere $509.

That device is kind of hard to use on bright sunny days, but some I know are pretty good with it. I have no problem at the HJ, but I stink pretty bad when trying use it at the PV.

We have one that is made out of an industrial paint roller (original length was 14 feet) that has an added base extension that allows it to measure up to 20 feet accurately. Cost was about $60.
Measuring the bar

The laser measuring device is expensive (on my way to a meet last indoor season mine "disappeared" from my carry on bag). But every other type of device I have seen or used touches the bar in some way and the is not as accurate as a laser beam touching the bar. I saw an official at West Point some years ago measure the bar - "yes that's got it" and when he took the measuring device away the bar bounced up about 1 to 2 inches. The other advantage to the way I use the laser (I have it mounted in a holder) the bar does not have to be brought to zero. (Which is very difficult, if not impossible, to do with some standards. OK just my .02

At a collegiate meet? Yikes... I know that wasn't me!
How long ago we talking? You can private message me if you like as I know nearly every official who works or has worked at the vault.
