After seriously considering mounting the GRT magnetometers at the wingtip, we decided to mount the dual magnetometers behind Bulkhead A. We fabricated a bracket to hold the two units exactly in line with the centerline of the fuselage and level with the waterline. The screws and locknuts at each corner allowed us to tilt the magnetometers as needed to align them accurately. This was a rather complex installation since we knew other builders had mounted their magnetometers in many locations successfully.l
