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.

Detonators? What was your land previously used for?

Morning you back gardens a minefield ? tread very carefully....

What’s on the other end of the flex?
Is there any writing on it, or a sticker?

I’m thinking float switch??

How many have you uncovered?

I would be surprised if it was a detonator of any sort.

What type of ground is it?
If it's a desert area they may be moisture sensors for an irrigation system.

@Ruzzell I don’t have a clue as to what that is but call City hall and have someone to come out and check it. The electronics inside is what I would worry about

I wondered the same but, no, ours is a residential lot built in 1901. Doesn't seem there would be electronic detonators at that time.

how many cores in the flex ?
Is it chunky enough for some current !
(don't touch cores with bare metal -
That Det things got me worried )

Cut the blue wire. In the movies, it’s always the blue wire

It's a trap. Cut the red wire.

Live life on the edge - cut all of the wires

Just order loads of carp of amazon....they guaranteed to walk over ya lawn!

when did amazon start selling fish?

I wonder if they are the transducers for a mole repeller buried underground in a garden. Each one generates a high pitched (modulated?) sound which moles hear as indicative of a potential predator - so they scarper from the area insonified by the transducer stopping a garden from being wrecked by mole hills and tunnelling. The wire goes to a power supply or amplifier.

They look a bit too well sealed to be emitting anything.

I bet they on there!

Stuck it in google image search , (that I'm not that good at)
with the curly bits it says --

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

 

[Andy78]

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?
