Shot Marker (Review)

[jlow]

Super guys! Thanks a bunch!

Her is a simple question - we have quite a few Shotmarker and some is showing problems so we would like to test all of them at once.

One idea I have is to line them up and be up close to them - close as in 10 yards away and not 600/1000 yards away and shoot at them with a 22LR shooting supersonic rounds. This seems like a quick way to test and since you are close, its easy to go through all the targets, call the line safe and go down to check/fix and then come back up and retest. This way, you can go through all of them quickly and then ID the problem child and send them back for repair.

I like this because it could be fast and cheap. My only question is would shooting the targets this close i.e. 10 yards confuse the sensors? So specifically, how close is too close?

I use a 22lr with cci stingers, step back 8-10 yards and shoot 2 corner shots, works really well and saves time. I started out closer and the muzzle blast was confusing the microphones.

Yes, it appears that this works. I talked to Adam and Laura at MacDonalds Innovations and this was the reply I got

"The lowest velocity it can measure is Mach 1.03 which has a 14 degree cone angle so at least double the width of the target in distance is a good rule of thumb that any valid supersonic velocity should fit within."

Here is a different question, the folks who run matches recently have told me that they ran across an interesting problem which is when using multiple ShotMarkers with the same access point, the targets appeared to be "locked linked" i.e. when a person change the target type and caliber, it changes these two variables in all the targets... They have been unable to de-link the targets.

I have not seen this in person, but I see in the manual under “Managing Multiple Targets” that the sample given have you give the targets the prefix “BAT-“, that I understand is allowing the targets to be put into a group. I think we unfortunately have not used a prefix but just given them numbers for names i.e. “2”, “6”, etc. Probably something we should change…. Would that cause the above observed problem?

Adam tells us that in group targets, when you change targets/caliber, you are normally given the choice to change the others and you can op out by saying "No". Not sure our guys have seen this?

We run 20 shotmarkers and use 3 different target groups. We have one group named 200/300-1, 200/300-2......, a second, 600-1, 600-2........and a third for f-class, f-1, f-2, etx. Due to a dogleg in our range where 600 yard firing points don't line up with the same target/number board as 200/300, we have to change target groups when we move from 300 to 600. Most ranges won't have to mess with that.

When I change one hub profile/target face/sighter setting etc, I get the option of changing all targets in the group, or just the one I am on. The f class group has a built in offset so the impacts are actually about a minute low to preserve the aiming point. If we have a mixed line of sling and f shooters in a prone match we can actually run 2 different groups so the shooters have the correct target face and scoring.

If you already have things set up and calibrated, just change the name of each target profile so that it has a name with a hyphen then the target number. (T-1, T-2, etc) Then you can make group changes and not have to change each target separately.

When running different groups on one channel, not all settings can be split. For sure the accursed 7-second delay must be on or off across the entire line, you can't have it on for f-class and off for sling.

Thanks for your reply. Yes, I think the problem here is probably the fact that when these were setup, they did not use a prefix with the "-" in their names, and I think this confuse the ShotMarker. I have asked them to change the target names in this manner to see if this helps so that they get the option of not linking the target face/caliber.

They renamed the target with the prefix and "-" today, but unfortunately that did not solve the linked problem. So it is something else.

One thing is this system used to work, but this link problem only showed up in the last couple of matches. To me, this sounds like there is a software problem in the machine and it needs to be reset - does anyone know how to do this?

Bought a shot marker system however having issues with system dropping a lot of shots during shooting a string
also when i test sensors in the tap sensor setting it seems to take ages when tapping each sensor before it registers on the system
I have checked cables and connections all seem ok with soild green lights on both the senser and reciever hubs anyone have any ideas how to sort issue thanks.

I had similar problems. Reach out to Adam. He will address it for you.

If this is a used system, check to see if the memory is full from the previous user, if so, you need to delete some to make space.

Wondering if anybody knows what that grey frame around your target is for?

I believe that’s the size of the defined sensor area relative to the chosen target

 

[jlow]

Oh! Thanks a bunch! It's good to know. Do you know where one find out information such as this? I don't think it is covered in the manual.

One reason I ask is because a friend of mine has a ShotMarker which appears to have a "contracted" grey frame i.e. one which is actually smaller that the target itself, and he mentioned one day that it was because his system was not properly calibrated which of course made me curious....

I just notice it moving if we introduce a vertical offset and one range has reduced size frames so the gray square is very small relative to a LRFC target.

Test it out, move your Y offset like 100mm and you should see the square move.

 

[jlow]

I just received my ShotMarker and made an aluminum frame for it. This was not my design but that of a friend. Having completed its construction, I am now wondering where I should place my actual target for aiming.

As you can see, the sensors in this design are not exactly on the four corners, and although their locations are very accurate width and height wise, it is not a true square. I understand that the target will need to be calibrated with the supplied calibration sheet, and the point of aim can be offset intentionally to preserve the point of aim (have not quite figured out how to do this yet).

But my question is assuming I do not want a POI offset and want my POI to be identical to to my POA, how exactly do you do this? I imagine one could put two strings in a X-fashion from censor to censor and glue down an actual target face using it for centering? Or do it simply by measurments?

Another question is for calibration, the calibration sheet does not have to be absolutely centered - is this correct?

Thanks for your help ahead of time!

 

[Jdne5b]

Yes. Put the X or middle of the target where the diagonal of the sensors meets in middle of the frame. Center the calibration sheet as best as possible so you can match up your screen with paper.

 

[jlow]

OK, that worked out, and will look something like this when the carboard backer is fitted and I can glue the MR-1FC to it - thanks again!

 

[Jdne5b]

That’ll be really close. Looks good!

 

[jlow]

Thanks again!
