Izh-46 and Electronic target scoring.

LukeP · Post by **LukeP** » Mon Oct 15, 2007 12:36 am

I'm wondering if electronic target work fine with izh-46.
Especially i think about the mechanism pumping air, with CLICK-CLACK noise of the lever and the "PIFF" when charging chamber. Is it a "Zero" on a electronic target? Is possible to use izzy with electronic target?

Thank you very much.
Best regards,
Luke.

Are you talking about an electronic target (Suis, Meyton, etc) or an electronic trainer (Scatt, Rika, etc).

You shouldn't have any problem with an electronic target providing that your pellets are travelling at a "normal" velocity. All of the sensing is done at the target. Noise at the gun does not trigger the target.

The position would be different with an electronic trainer. Although it is possible to do so, it is not a requirement that you live fire. Your most difficult problem would be mounting the sensor on the gun in a position that is not disturbed by cocking the pistol. On the Scatt, noise when the sensor is not pointing in the general area of the target is not counted as a shot. You can also adjust the volume required to trigger the system. I presume the other systems have similar facilities.

Yes, i'm talking about electronic target (Suis etc). Velocity of pellet i think is more or less around 130-140 m/s, like most of target match pistol.
My doubt is (for example) if i discharge the air without the pellet... the target must give me a "zero", but no pellet arrived to target. I don't know the method used by the target to check this.
So i'm fear that the "piff-puff" noise of charching izzy lever's, can effect target and give "zero", like a gas discharge without pellet, or a pellet out of target.

Thank you.
Luke.

Seen a few very low velocity air pistols rip the paper roll on electronic targets and this cuased blocked feeding of the target roll.

The Sius system will not pick this up, it will only react to a pellet arriving at the target box. It doesn't matter what gun you use, if you just discharge air without a pellet it will not give a zero. In that respect the Sius system is identical to paper targets.

The cocking mechanism doesn't make enough nose to register a zero.

Discharging gas without a pellet will register a zero.

Exactly as it should.

Don't know about the SIUS system at the world cups, but the SIUS we have in our club (which looks standard) for sure doesn't register an air shot. No pellet, no score. The mics can't be so sensible as to register an air shot, or they would pick up impacts from the next target, too. The only reason I can see why an air shot would be picked up was if additional mics were used at the bench, as with the 300m rifle system.

Are you sure about that Steve. How does it sense that the gas has been released from nearly 10m away.

I may be wrong but I always thought that the fullbore rifle system used muzzle flash sensors, not microphones.

I'm no rifle shooter, but some years ago, we had a lot of problems at the national champs with the 50m system - where they tried to use bench microphones, at that time and according to SIUS the same idea as in the 300m rifle systems. Haven't kept up with potential technological progress, though.

D'OH!

David you are right.

Only the "combo" ranges (where both small bore and air are shot) will even *have* the mics at the shooting bench.

And I don't think they will pick up the discharge of gas (way too quiet for the "crossfire detection" system).

So-o-o-orry . . .
