Natural EM Review

TriField Natural EM meter, Magentometer. Very useful under certain circumstances, very difficult to use in field. Most effective when used as a stationary monitor with a dedicated camera.

Dossimeter Review

Dossimeters, Radiation Monitors, Not very useful.

Victoreen Geiger Counter Review

Victoreen Model Geiger Counter, very useful in theory, design makes it more problematic. Dubbed 'the brick' for obvious reasons.
