Vely Interessting,

To share with you my own installation.

I dug a hole.
Put three holes in the bottom of a zinc plated steel trash can.
I pounded three tar coated surveyor stakes into the ground
leaving six inches of stake above the ground to level later.
I placed the can into the hole with the three stakes
coming through the bottom of the can with gaps between
the holes and stakes the can went over.
I took a heavy polished marble tile and glued
it with goop after leveling the stakes.
I gooped the geophone to the mable tile
after placing it on the tile.
I wired the geophone but used the wrong conduit.
PVC instead of galvanized steel.
It was cheaper.
I insulated the Can lid with spray foam.
I put chemical cat litter in long socks
tied dental floss to the socks and lowered them into the can
around the geophone.
I put the lid back onto the can.
The lid is sitting on the can with its rim
just above the4 ground.

It has now been that way several years with no problems
other the hot summer days.

The most difficult thing was pounding the stakes into
the hole and getting it right.
You really need a special tool to
do this thing right.
To get the stakes both vertical
and in position and in the correct triangle
for leveling the tile.

I would be too old to do this thing again
without dieing of a heart attack.

Cheers,
geoff
