Hi Jon-
I have used it for years in Down Hole (3 geophones down the hole) seismic
surveys-  Since it has twisted pairs this reduces the noise pickup and it
is cheap.  It is #24 solid wire which breaks real easy if it gets moved a
lot.   But once in place it should do fine....Jim

Hi Jon-
I have used it for years in Down Hole (3 geophones down the hole) = seismic=20 surveys-  Since it has twisted pairs this reduces the noise pickup and= it=20 is cheap.  It is #24 solid wire which breaks real easy if it gets = moved a=20 lot.   But once in place it should do fine....Jim
