Hi Paul
Many thanks for your swift response. The reason I am keen to get the geophone working is because we are trying to monitor the blasting activity at a quarry local to our community. The quarry company is being very sneaky and have just applied for a massive extension to the quarry - even though is was due to close in 2025. Local residents are very upset and we are gathering data that can be used to illustrate the impact the quarrying activity is having on the local community including the landscape and wildlife. If I can get the geophone working my plan is to put several around the local area to map the effect of blasting. In other areas, we have been developing a multisensor underwater environmental monitor using the OLA as the basis it would be great to talk you through this at some point as we hope to deploy it in various parts of the world to collect environmental data remotely.
Kind regards
Mark
