  1. I want to add too, that operating a shot timer (regardless of brand or type) in this sport is an art of its own, take one isolated controlled case where you can do above mentioned technique it will work just fine, but in most match setups I have seen any squad you look at has mixed guns, you can have very loud open gun right next to super-quiet PCC, some loads are so quiet I don't even know how they push bullets out of the barrel. And sound pressure spreads somewhat unpredictably at the range, everything matters, how you point a timer, if there any obstructions between microphone and gun and by obstruction I don't just mean large obstacle like a shooter's back or a wall, in my tests, as you hold a rifle even elbow can be a decent obstruction for the sound to travel adn effectively hit microphone, not to the point to completely blocking it but to the point to make it inconsistent, so if timer's sensitivity is not calibrated to particular gun, shooter my turn left and you may miss a shot being picked up. If someone shooting an open gun that projects alot of low frequency noise close to the mic and there is a drum barrel or a wall nearby, it actually may pick same shot twice as it reflects if sensitivity set too much. Remember that video on youtube someone shooting a shotgun and when he is done, he shows clear, and slams slide back and timer picks up a shot adding additional few seconds to his total time. On hybrid or indoor ranges with narrow bays and wall dividers echo is a big enemy, if sensitivity set too high and echo suppression too low you may pickup extra shots which does not sound like a big deal but when fast shooters shoot smoke and hope every 10th of a second matter and you may pickup that extra 10th (or more) on last shot and some timers obscure that from you by only showing one number on display so unless you deliberately scroll through shots and check split time on last shot you wont know that. I also, not too too often, but have seen cases where gun perceived as quiet because it does sound somewhat quiet but it is actually received by microphone as loud, and vise-versa, that is because when timer's microphone gets hit by audio wave everything matters, energy, peaks, length, frequencies, etc. Also as match progresses through the day and ROs get tired less and less attention may be paid to timer settings between shooters so yeah, so yes, we need to pay closer attention to shot timing aspect of this sport but always remember of its challenges and nuances. My 0.02 anyways

    Pact timer buttons

    Mine does that too, go button seems to be a tight fit (i.e. gap between the button sides and casing opening too small) so when it springs back sometimes it bites the edge and sticks a bit, happening to other two smaller keys sometimes too. And yes to second, sometimes I have to press it twice as it does not accept first push, I bought mine used off ebay so I am not sure if this problem existed from beginning or just repeated use wore out keys and contacts a bit.

    The 'which timer' thread

    There is a new timer that is not on the market just yet and currently undergoing field tests, but I will be happy to soon report how it performs and its eta to the market once I have that info on my hands. So far what it has to offer is very promising: standard batteries with battery life outlasting other timers, clever shot detection algorithm, multiple pars, largest font to display shot time, adjustable wide range sensitivity, adjustable beep volume, ability to review few recent strings simultaneously, delay/instant/random all fully adjustable, compact, ergonomic, one hand operation with minimal number of buttons and simple intuitive interface, and more.... Just heads up all

    Draw speed

    My suggestion: set camera looking at you from the side and record video of yourself at slow mo if you can (most today's smartphones or gopros can do slow mo), basically record whole sequence of events that happen, i.e. beep goes off, your hand start moving, grabbing handle, pulling gun out, moving it up, etc, the whole thing few times, then watch and study what you do and where are the delays that you can shorten, for example I think I you may have a delay between timer's beep going off and your hand starting to move, you can probably easily shave off 0.1 - 0.2 seconds there, then possibly also when your hand lands on the grip it may rests there for another 0.1-0.15 seconds before you start moving gun out of the holster, etc. Then for things you want to improve address them individually, for example: if you hesitate too long after beep goes off, find yourself an exercise that improves your reaction time, if you grab a pistol but dont start pulling it out fast enough, isolate that particular motion and work on it and then re-integrate it into whole draw sequence.

    CED 7000 External battery

    To me, there is just so many things to keep an eye on with rechargeable batteries whether NiMH, Li-po, Li-ion, etc, is it too hot, is it too cold, it is overcharged, is it too deeply discharged, is it a correct charger, is charger available at all, etc? Just sayin'.
  7. Wow, so many cool memories surround all this stuff, absolutely love it, I think I got the original than, it says 1983 and it also has lead acid battery inside and it also says Owner Name upon turning on
  8. I'm very excited, recently I've got in my collection a shot timer from 1984, just as featured on the pages of 1985 American Handgunner magazine here on page #28 https://americanhandgunner.com/1985issues/HSO85.pdf I like how it says in right/top corner "new smaller lighter package".
  9. Thank you @racerba for a reply, very good advises, #4 is awesome, while naturally understand that obstacles block sound did not even think about such practical application of that knowledge
  10. I have a question to those who have experience of running matches with shot timers, how do you universalize, so to speak, sensitivity setting on a shot timer, so you don't have to tweak it between every shooter? What are the traps for young ROs when it gets to shot timer's sensitivity? I understand that different shot timers require different approaches so this question is a bit abstract, but please maybe share what you can from your experience? My concern is that if you set sensitivity too much, it may pick up slide release sound or shooters from adjacent bay or stage, or shotgun cycling sound, or any other loud sound that is not a gunshot. But if you set sensitivity too low, you may not pick up shots if you too far, for example if its a USPSA or other match where shooter is on the move and RO did not catch up yet to shooter he may be too far and sensitivity of the timer may ignore the shot? I have seen at couple steel challenge matches when if RO set timer too sensitive to pick up some of those .22 rifles it was picking other shooters from adjacent bay so sensitivity had to be set higher than usual but not all the way and RO got timer very very close to the gun, like literally 10" close. ThenI have seen a YouTube video where someone claims that he was timed wrong because at the end of the stage he unloaded a shotgun and sound of unlocking triggered timer. What is the best way to manage shot sensitivity to get the best out of it with least adjustments? How cautious you need to be about proper sensitivity setting? What are the things to be on a lookout so you don't run a stage just to find out that you picking up shots from adjacent bay or not picking up shots at all, do you have two timers, one for loud guns and one for quiet guns or you manually juggling between two sets of settings? Do you rather try to have higher sensitivity and stay further back from the shooter or actually have lower sensitivity and stay closer to shooter. Any info regarding this matter is very welcome and appreciated. Thanks in advance.
  11. With my current sight adjustment patterns are: 1. All 124 or 147grain subsonics go dead center 2. One particular brand of ultrasonic 115grain goes dead center too 3. Anything else that feel hotter and kicks more goes left, not low/left, but just left. So my scientific conclusion is that either I know it and gripping gun tighter or slapping trigger etc..... or indeed there is an an earlier unlocking (or other phenomenon, which as stated above has been observed by others) with hotter bullet causing barrel to constantly point a bit to the left. I can be wrong, but that is what I believe in and my gun feels my believes.

    Tricks to get front sight off my XDM

    I ended up using dremel to cut it out, scratched slide a little bit so be careful if you do not want to scratch the slide. I think it is also glued because once removed there was a definitive outline of the sight that I had to remove with alcohol. I think the only realistic method to remove it without cutting is to use pneumatic hammer. PS: r u getting .100 blade? good choice

    Acquiring the sights after draw

    Not sure for how long you have been shooting or basically how embedded into your brain is this particular muscle memory. But I'd say, if you commit to 5 - 10 minutes of daily (every day, no exceptions, weekens and holidays) exercise of drawing pistol, acquiring sight picture before breaking dry shot, does not matter how fast, just do it right. In about 2 - 2.5 half month you will embed new technique into your brain and will be good to go just periodically practice that. Do not force it if you feel like you ready to speed it beyond your comfort, you will see at first there will be no visual improvement, then you will be observing little improvement every day-ish, but very little, keep doing that, and then in about 2 - 2.5 half month it should happen out of nowhere without warning, you will pick up a pistol and it will become a second nature, you will be surprised. But you need to do it every day to properly rewire your brain, e.i. do destroy old neuro-chain and build a new one. ps: Additionally when you go to sleep, just for 1 visualize pulling pictol out of the holster, raising it up, seeing that sight before breaking the shot, 1 minute is enough. pps: if you catch yourself rushing too much and breaking the shot without seeing that sight, stop, step it down a notch and repeat at slower speed but do not let you do that mistake again.
  14. Thanks everyone for suggestions and info, I did little scavenging over internet to see if there are other people with similar questions and just like you saying above it is a known phenomenon. I am having hard time understanding how that is possible for bullet to deviate left and right, assuming barrel crown is not damaged, but perhaps maybe different velocities can cause different unlock time, thus causing shots to drift left, etc. Anyways I was happy to find out that this is possible because, frankly, it was driving me nuts, I sighted pistol, made some super nice groups, then loaded different brand ammo and shots low-ish left-ish, hard to diagnose because it is a classic trigger jerking/fingers tightening symptom. Well, with above being said, thanks everyone for input, I will all try to mix different brands of ammo together in one mag and see is that will cause group to be split into two sub-groups.
  15. I went to range today to sight in new adjustable sights and came across weird issue. I can't quite understand if this is me doing my part wrong or indeed some brands of ammo can shoot slightly to the side when other brands straight. I had 4 brands of 9mm ammo on me, 1 box each: two boxes shoot very straight, pretty much dead center at 5, 7, 10, and 15 yd (those are may comfortable -ish distances, anything after that I would not trust my groupings) well, of-course at 15ys shots are slightly above center, but horizontally they still centered. Two other brands hit target about one inch lower left at 5 and 7 yd and so on at further distances, this ammo is also hotter than first two brands. I know depending on ammo, its velocity etc... shots can hit target at different heights, for example if one brand of ammo hit target dead center at 15yd, other brand can hit it 1" above etc... But not sure that it can drift left or right unless I jerk the trigger or do other trigger error on my side. Is it ammo or is it 100% me?
