Hydrology and recharge projects that need deep, depth-by-depth water profiles still rely on neutron probes. Lowered through 45–50 mm access tubes to 3 m or more, the Am-241/Be source senses a sphere of 30–50 cm radius over 15–60 s counts, reading 0–60% volumetric. Buyers should note that licensed operation and dosimetry are required locally.
