Earth Magnetometer – IC-EM2

Features:

– Displays field strength up to 199.999 micro teslas
– A relative zero mode subtracts the background field from all subsequent readings so there is only a 1,2 or 3 digit number to watch.
– Backlit display can be turned on.
– Lightweight with long battery life (see specifications below).
– This is a vector magnetometer so the direction of the field (as well as strength) can be determined (but see full description; this feature requires a longer time per measurement).

Applications:

– Determines both the location and depth of a buried target of magnetic material.
– Measures the presence (and amount) of certain minerals such as black sand (associated with gold deposits)
– Measures inside DC Solenoids (probe is bent into L shape to measure this).
– Can in some cases locate voids or caverns in a given stratum if at least a trace of magnetic mineral is normally present.
