Shotmarker protection

[Ccrider]

Just curious as to whether anyone has found a steel box of sort that you could put your sensor hub in. My luck is that someone shooting in their AR at 500 yards will lob one over and hit the hub. There are no pits where I will be shooting so the hub will be exposed.

I have not been able to find anything pre-made so I am leaning towards making a box using AR 500 facing the firing line with a two - three inch spacer and wood back where I will mount the sensor hub. That should give me clearance between the plate and the hub allowing for vibration. Thoughts?

Have you considered dropping it down below ground level?

There is no pit so I can not drop it below ground level.

Get any cheap AR500 IPSC target and stand that up at the base of the frame. Put your sensor hub behind that, and run the wires up to the mics. Problem solved.

Honestly, unless you're shooting at really long range and/or are letting people with really bad / no zeroes shoot at your e-target, simply sticking the hub down and off to one side - like on one of the legs of the target stand - is usually more than enough. Unless someone is shooting patterns - literally - they are very unlikely to be off both windage and elevation by that much at the same time. But if it's a concern, and hey, those hubs cost $500 USD to replace... stick an AR500 IPSC at the bottom like described above and rock on.

I understand that but why not dig a small hole?

We have our transmitter hubs below line of sight on our 500 yard range.
Some dumb ass, with a "bumped" scope still was able to barely clear the concrete wall and lobe one into the transmitter.....
It is a $545.00 accident!

This is what I want to avoid. I think o will go with the AR plate box.

I bought a 6" AR500 gong and a couple of hooks from the hardware store for about 20 bucks. Then I covered the back of the steel with some foam rubber matting I had in the shop just in case the shot swung the gong back and it hit the transmitter. If the antenna or the antenna cable gets hit I can live with losing ten bucks

edit- you don't need a box, just something to protect the front. Any lead splatter from a hit on the gong will go perpendicular to the gong's face. My frame is made of pine

Here is my solution, a piece of 1/2 thick AR500 in front of the box.


This is not foolproof, looking at the white cable coming out of the right side, there is a hole in the panel caused by a faulty bullet landing sideways right on the cable. I replaced the cable.

As a safety concern, to possible people being in the pit area, I removed the AR500 plate, so there could be NO possibility of a projectile hitting it, and shattering and endangering any people or other items in the pits.
I then mounted the box on end, to provide a smaller cross section, and reduce the possibility of a strike on the box.

cables, wifi antennas, and even the wifi antenna extension cable are easy to replace but if I were to hit that sensor hub I would be alternating between cussing and crying for a week

BTW that is a nice looking setup that you did. I like those little cable clamps you used, I will be ordering some of those for my frames

Why not put a piece of AR500 steel on the back of the frame, and then Velcro the transmitter to that. No chance to hit the transmitter.

I will do something similar to this. I will put the AR500 gong off to the side and the sensor behind it but not attached directly to it and then use the antenna. Someone pointed out that vibration from the gong if it is hit could damage the sensor. Makes sense to me. I may glue some foam cushion onto the sensor and then use Velcro to attach the sensor to the gong. Simple but should work fine.

How about a sandbag or two? That should eliminate any of the splash anyway. I guess it all depends on the layout of the range and angles of possible fire. I have never shot e-targets without some pit protection. It would make me sick to hit one. Best of luck

The target frame is designed to fit the target frames at the club range. It is mounted by two steel straps that drop on the top crossmember of the range target frame, and there is no room on the back side.

I use a similar setup to hang the target. This is how I did it. There is a 1 3/4 inch air gap between the sensor hub and the target but I taped a piece of 1/2 inch dense foam there just to be on the safe side. I suppose I could spray a bit of paint on it someday, but I care more about function than form

Thanks. Is that a 10 inch gong? What size boots did you use?

8 inch, I posted earlier it was 6 inch but checking today it was 8 inch. 3/16 16 bolts. The target frame is upside down to make taking the phots easier, the transmitter is on the bottom of the target

I have my SMT Solo hub behind a AR500 plate. If it gets hits the round will have to be coming back at me.

Another thing to do is coat the AR500 with a very thick coating of spray on bed liner, if a round does happen to hit the AR500 plate it will keep bullet spall from damaging the sensors or wires.

Beautiful. This is exactly what I was implying.
