The IML-RESI MD300 is a driling instrument working purely mechanically that does not record a measurement curve, neither electronically nor mechanically. The user feels the result and can read the penetration depth on the 300 mm scale. Often an abrupt and fast penetration is perceptible when the instrument detects a rot zone. Even the annual rings of conifers can be noticed.
