Advantages
Key Features
- 73 mm tubes to 5 m, 54 mm tubes to 10 m — samples in soft ground without a rig or a mast.
- 1,500 blows/min at 20 – 55 J: percussion sampling and N10 light dynamic penetration testing in one tool.
- 23 kg with a 52 cc two-stroke engine, carried by one man between points.
- 1.3 L tank on a 25:1 mix; refuel from a can in the field.
- Built for exactly the strata where a core rig loses recovery — silt, clay, sand and fine gravel.
- Impact energy adjustable across 20 – 55 J to suit loose sand or stiff clay.
