I am using some geophones to record strange ground vibrations which make a
up a local hum phenomenon like the Taos Hum in the US.

The recordings point toward a  technical  origin at a depth of 100 meters,
possibly secret tunnels.

But I have a practical problem: The stiff black geophone cabling is
difficult to connect to my recording equipment. I have used XLR connectors,
but when handling the cabling, the connectors sometimes break loose. The
soldering is stressed, and it eventually breaks up. This is causing some
failed recordings.

How do you most easily make reliable connections?

I have heard that geophones sometimes come with special connectors for
seismic equipment, but I have never seen these connectors, and they may
even be hard to find on the market. Perhaps these connectors are ideal; I
don't know.

Any opinions?
