The 3ft Measure Head Assembly (3’ MHA) from Geo-Log is our most iconic measuring head in North America. It is ideal for cased hole and perforating operations. Each revolution of the Three-Foot Measure Head, measures three feet of cable. The cable takes a 22-degree deflection path to provide a measurable force to the load cell unit, which gives line stress or weight data to the operator.
