Truck-mounted build on an 8×4 chassis.
RC Drill
Reverse-circulation exploration drill.
Sample-recovery exploration rig that uses compressed air through hollow inner tubes to deliver continuous rock-cuttings to surface. Drills 128–150 mm holes to 300–350 m vertical at angles 45°–90°. Ships as the crawler-mounted DRC 350 or the truck-mounted RC400 - the drilling equipment is the same across both; only the mounting differs.
