Gaff : Considering the pre tournament comments you were making about wrong divisions etc, it comes as a great compliment that you had a really good day.

thankyou for that aknowledgement Ralph, my intentions are always to have fun, and assist, but unfortunately my shortish temper and limited understanding of the english language, sometimes make my written word that little bit too harsh! and i was complaing on behalf of our AM B team not for me, cos my teams intent was on winning Div 1, which we so neally did! dam and blast

what are the other options?.

exactly what you have mentioned below, just test the lot together, and if you do not have the equipment to calibrate them then leave a note on each of the higher reading chrono stations stating that what ever your reading is reduce it by X to allow for the inaccuracy.[/B][/QUOTE]

If things had started ok on sun we could have done some sort of calibration between the static & handhelds but as you know even the statics vary from field to field. I will try to do some sort test before the next leg and possibly have the most consistent in situ.

My major concern is about saftey and that's where the handhelds come into their own. We all know that it is possible for the less honest to manipulate the tech in their markers during play and this needs to be discouraged. If the hand helds put the fear of Robbo (god) up them by being less accruate then so be it most would say. It does mean that some innocents may get trapped as well but as i say, what are the alternatives..

the handhelds are definately the way forward! safety and gun cheats need to be very high on the list at the mo i believe, but there is a set of user guidlines and instructions for use that need to be observed in order for them to work accurately. what i am getting at is.......if you have the handheld under your barrel at a slight angle the reading will be falsely 40-50fps high, if you have it at 90dgrees to the barrel (preferably using the sling that comes with the unit) then they will read accurately...try it you can get readings of 285, 290,292 then 320, 330,328 just by moving the handheld.

The other problem is that most teams run their markers with no room for error.I dont know what the percentages are but if you set it up at 290fps it only leaves you 10fps to play about with.Is that enough? only the player can decide.

Gun/Chrono/hopper tech has moved on a pace but have the paintballs? Lots R&D money go's in to make the best paintball but as far as i know you will never get a perfectly sphereical ball.Thats why the militaries stopped using musket balls as they could never predict which way they would fly everytime. All you need is 5-6 differently shaped paintballs to go over the chrony and there go's your 10 fps.

Still i will seek advise about handhelds/statics and see what improvements can be made.....if any.

Regards Ralph

with the new top line guns (well the x-mag for sure) that we use, we can set our guns at one tourney and then fill them at the next to find that they are still reading exactly the same, also if we get the odd ball that takes the shot over 300fps the chances of the next two being odd shaped as well is very low, as the test by the handhelds on field should be 3 shots measured then the average fps of the three taken, you do have an amount of safety.

once again i would like to say it was definately the best marshalled one yet, thanx to all

Gaff, its been a while since I've shot an RT based gun (ie, original RT, Retro Mag, RT pro, E-mag, X-mag) but wasn't there a specific way of chronoing those guns in the morning because they were known to increase velocity after shooting long strings?

Think the RT valve used to heat up during high ROFs and the velocity would jump by a significant amount, certainly know a few times old teammates had been caught by it. AGDE used to have a chrono procedure on their site about it, haven't looked in a while so am unsure if it is still there.

 

[gaff]

RT valves used to have that problem but i have never had one so i do not know whether there is still a proceedure for that.

the new X-mags have a new aluminium valve which is far more efficient and i belive completely stable, i will ask Sosta and see what he says!

the three shot test should clear most probs even with a high first ball, unless the gun is set hot tho.

 

[Dave S ECI]

The working is the same on the aluminium valves as the original RT valves I believe, same as Retro valves etc. I beleive the probelm arises from running higher input pressures into the valve, the gas heats up as it recharges at speed and the gun shoots up after shooting a bit of paint until the valve cools.

The problem was that it wasn't a odd high ball, the velocity would be raised consistently and so a clearing shot would have little to no effect. The old way of chronoing an RT used to be shoot a ball and hold trigger then release trigger and fire again as quick as poss. should give you the velocity of the gun in a rapid fire situation. John would be the man to ask though.

I'm fairly sure that other non-RT valve guns can be made to shoot up as well.

 

[gaff]

just spoken to Sosta and he has said pretty much what you have just said Dave, the valve will produce 3-5fps more velocity after a stream of shots, this is why he makes us chrono at 280 - 290 so that we have that safety zone.

you can tell when people have their input pressures too high cos if you switch the gun to manual the trigger becomes reactive, altho it is not a good idea to use this in a game cos then the electronics including the eye are redundant and ball breaks could occur.

apparently playing with dwell times on other markers can do pretty much the same thing, but i'm not technical enough to either explain or understand fully what thats all about!

 

[Dave S ECI]

That sounds right Gaff, reason I remember is that back in the day people used to run 900-1000psi into the back of RT valves to get the reactiveness going but they then suffered massive shoot up.

Guess with the new electric trigger = no need for reactivity, therefore lower input pressures and so lower shootup if at all.

It is something that is worth thinking about for all markers.

 

[gaff]

yeah i agree, there seems to be a little gremlin appearing in the distance tho with regard, cheats for guns, what i mean is its not gonna be long i think until someone will have to bring in a scrutineering section for markers (like in motorsport) to ensure that there are not cheats on guns. and the better the technology the more cheats there are available
