Claim:
An aerial-drop dual-impact penetrometer system comprising: a primary penetrometer formed as an outer shell having an outer shell fore body, for primary impact into a target area of soil on the ground, connected to an outer shell aft body having a rear recess therein; a secondary penetrometer formed with a narrow-width, secondary fore body, for secondary impact into an adjacent target area of soil on the ground, connected to a secondary aft body sleeve, wherein said secondary penetrometer is combined in a unit with said primary penetrometer by at least the secondary fore body being received in telescoping fashion within the rear recess of the outer shell aft body of said primary penetrometer; and an ejection mechanism provided within the outer shell aft body of said primary penetrometer for ejecting said secondary penetrometer upwards from the primary impact area into the area to fall to the adjacent secondary impact area on the ground.
