Applications - Soil and sand

Sites of use - Geology and educational institutes, and agricultural organizations

Construction - Includes one handle, one auger, one cylinder, two extension rods - a light, shatter-proof plastic carrying case is sold seperately.

Method of use -  After assembling the parts, remove visible stones and other debris from the surface of the soil to be tested.

Hard soil - Place the cylinder on the ground; insert auger through the cylinder. Position the auger vertically and apply pressure while turning the handle until the drill has reached a depth of approximately 20 mm or is firm.  Now a minimum amount of pressure should be applied to keep the drill cutting until the full length of the auger is buried into the soil.  Release pressure and make a complete turn sharply withdrawing the auger from the soil. This will remove the bulk of the soil from the hole.

Soft soil - Use of the cylinder is optional.  For easy operation, follow these instructions.  Start the drill one or two turns; stop and pull up slightly to loosen the soil around the drill.  Then turn one half turn and repeat the above mentioned procedure.  To obtain a full auger, make about three turns and then pull the auger and remove soil.  For deeper sampling, proceed as above.

Sand -  Use cylinder and follow instructions for soft soil.
