When I started using GPR, the antennas were mounted in small skid trays that allowed us to go anywhere. Nowadays, everyone has these carts that are more effort to push, break at the first sign of a hidden bump and are a pain in the bum to turn.
How many of you still use a simple skid tray to collect GPR data on-site, or are we all moving away to the carts?
If so, Why?
