Hi all

Yesterday I did switch geophones and I did start to use a diffrent
geophone that I did buy last summer. Based on the data so far, it
appears that the geophone picks up the wind even if he is underground. I
do not understand the reason why this happens. The geophone also picks
up limited amount of noise from my block, but the distance from the
house is ~8 meters. The depth down to the sensor is ~80 cm, that is why
I am surpriced of seeing wind noise.

I also did change the connections from the geophone and into the main
cable, I now simply wire the wires together and I add a simple wire
skrew with a plastic shield to make sure that the connection doesn't
loosen up.
