the big red box old and new style, the yellow triangle thing
Orracle with belsales ram and qev's, E2 (and 420 trigger mod sometimes for messing around) slik bolt (I love this), ccm aluminum pump arm, etc.
I think I own 13 or 14 cockers most of which are pretty much maxed out, so that pretty much covers it.
It works! accurate, easy, small.
That you cant set it on a table and shoot over it.
I often host group games with unknown walk-ons or people who are new and afraid of pain. A chrono, helps greatly to allay fears of newbies and parents, and gets more girls playing. It also helps to solve the problem of the jerk kid with a red spring in his gun shooting 450. I mostly use it to fine tune guns though. Having a perfectly tuned reg greatly improves performance, and that is very hard to do without a reliable chrono.
I bought mine when they had just barely come out, so I think I have had it for nearly 2 years, ro maybe a little over. I am not completely sure, but enough to be sure.
I narrowly bought one of these on a well known auction site for $65 shipped... Less than the yellow one at the time. It works much more reliably than the yellow one, will read low velocities... it starts somewhere around 200, which is useful for bringing up regulators up from zero, or malfunctioning guns, so you can know what is happening.
I also find the low cut in point to be very valuable as I bought it to host reball events for a church. The yellow one wouldn't read low enough to help as reballs are supposed to be 220FPS or was it 230? It's been a while, but it made the thing useful vs. useless.
It is not nearly as picky about how you hold it. This is a big improvement. The yellow one either gives wierd or no readings if you don't hold it perfectly.
It works on "dead" 9v batteries, which most paintballers have lots of.
It is portable, and gave the same readings as the 'red box'
3 digit display! much nicer
You don't have to reset it between shots , so you can just snap a few shots and see what your gun is doing.
Weakness: Very Minor, but I want you to have the whole picture then buy it.
The ROF feature is a nifty idea, but I am not sure how trustworthy it is, not too much of a problem there, as my guns have a display for that, and I can hear if it dry fires in a string.
The real problem is that the rof feature cuts in at 5bps, which can't be turned off, so you can't check for shootdown, and it often engages when I am just snapping shots over it to get multiple readings when crhonoing a bunch of kids' guns.
It is easy to not hold the button and lose your reading.
I wish I could fire a string of say 10 shots and have it remember them, so I could know how consistant my gun is at higher rates of fire. I think this feature would help for sweetspoting regulators. If it would just remember the last velocity of a string and ROF, I would be ok with that
The only major annoyance is that it is small enough to misplace, but that is my fault...
Buy it. It is easily the best I have used and by far the best deal. no qualifications. I think this is an excellent product, and would only buy a big red for a field station at a regular field, I would choose this over the yellow one if the price tag were $25 more. It is just easier and more trustworthy. I think this is the only 10 I am ever likely to give.
