The hand carried enhanced penetrometer includes an electrical linear actuator system to advance a soil penetration rod into a test site soil during a penetrometer test. The penetrometer also includes a base plate system that uses an operator's static body weight to anchor the penetrometer to a test site surface during a penetrometer test. In operation, an operator places at least one foot on a penetrometer structural base plate and activates the linear actuator to advance a penetration rod into the test site soil. The tripod embodiment of the system includes an operator's seat that allows an operator to conduct a penetrometer test in a seated position while passively anchoring the penetrometer in place at the test site. The invention includes monopod, bipod, and tripod embodiments.
