What is this?

[Ruzzell]

Does anyone know what these things are? We keep digging these old things up in our yard. They appear to be a hard plastic with some kind of electronics inside them. Thanks.

when did amazon start selling fish?

I bet they on there!

Stuck it in google image search , (that I'm not that good at)

I’m still chuckling at the poor fella waking up to the word “detonator” from @DPG ??

They certainly look a bit rough and ready in their manufacture. Just clear tube chopped squashed and sealed. Certainly not made for appearances so perhaps made to be buried. Chopped off and left in the ground after their use was over instead of digging them up.

Some good theories so far, I'm pretty intrigued to be honest. We may never find out though if they are some homemade project.

A good way to figure out their use would be to hand them to someone good with electronics and get them to analyse the contents. BigClivedotcom on youtube springs to mind.

I'm intrigued too now.

How big are they?

Thanks, all, for your input. I'm attaching a couple more photos. Several of these were buried just under the surface of the ground next to my garage. We live in suburban Philadelphia, so I don't think I have to worry about them being some of kind of leftover war ordinance or something. But I am a little hesitant to try to cut them open, in case they are a type of detonator or so. I'm intrigued and surprised that they aren't instantly recognizable to the electricians in this forum.

Telephone joint box?
Or simply a terminal for capping off a single cable.
How many cores?

It’s much smaller than I initially thought from the first photo.

 

[Baddegg]

Agree with @littlespark,looks like telephone cable are they hard to touch?....gel filled?

 

[Dan]

Can you cut one open and see if there are markings on anything inside?

 

[DPG]

Ah, it's transparent plastic. I thought it was crimped metal tubing. Could just be a cable joint, although why you've got so many of them I don't know.

 

[telectrix]

hit it with ahammer. if it don'tgo bang, then it's not an electrical problem..

Area limit for automatic mower ?

 

[telectrix]

it's a condom for a guy who's had the snip/infertile.

 

[freddo]

What is at the other end of the wire? A single core, several wires?

 

[James]

I was originally thinking they might be temperature sensors or p.h level sensors.
however, I am leaning toward the mole repellent device that was mentioned by @marconi

it seems the most logical suggestion so far.

as if it was a sensor, it would probably not need to be in a large sealed tube.

please don't take what is below too seriously **

If you are at all concerned about them being explosive, then DO NOT put them all in a bag, bang them down on the counter of your local council and say "are these things explosive?"

You will get an answer, I am sure, but you might have to wait a couple of days (under guard) whilst they do a few checks on both you and the contents of the bag.
