An explanation… by Brian Newham
Believe it or not I am in ‘the tent’ trying to use the GPR. With me inside the tent is an insulated plastic box which we modified to house the GPR and several hot water bottles to try and keep the unit warm. The tent is trying to shelter me from a 30 knot wind and keep the drifting snow off the GPR unit. It worked to a limited extent but it was pretty uncomfortable and very hard to use the GPR effectively. The idea has been shelved for long term use!
