I'm contemplating another spin-off project for burying my 3 axis geophone in a new site in the back of my property.

I have one of Larry's used orange geophones (Mark Products 4.5Hz 3 component L15B Sensor) in the shape of a  "margarine tub" as Larry has pictured on the PSN website, (See http://psn.quake.net/geophone/index.html),   

I was thinking of replacing the housing (which for me is broken and cracked in several places), and vertically stacking the 3 geophones  (in the same axis orientation as the original container), and building a water-tight  6 to 8 " long  2" dia. PVC water pipe "torpedo" to be placed in the bottom of a 6 foot deep  6 inch  diameter bore hole, surrounded by sand. on all 6 sides.

My question for you all is  will there be any noticeable magnetic interaction between the 3 units I need to worry about with stacking them about .25 - .5 inches apart inside the PVC tubing?


Thanks,

Dave Willey
