The 400 series from Strike Manufacturing is designed for medium to small sites and minimum disturbance. Typically, this rig is mounted on tracks or comes truck-mounted, but it can be skid-mounted for remote areas. This rig, depending on the power package, will drill in excess of 3,000-foot boreholes. In trials, it has drilled 1,500-foot air rotary and 1,600-foot core holes. Mounted on a tracked under-carriage, the rig is suitable for exploration drilling. When mounted on a two- or four-wheel drive truck, it’s ready for geothermal drilling, but also can double as an exploration drill if the access is reasonable.
