SEARCH
Micro Box
The Micro-Box method is used
when there is more than one
buried subject within fine search
range. In these very close
proximity cases, the micro search
strips (or the 3-circle method) may
not provide a sufficient resolution
to reliably separate and thus detect all of the closely buried
subjects. Apply the micro-box when more than one sound is
audible at the sound check at distance 3.0. Find the point of
lowest distance indication of the closest buried subject and
visually mark that spot. Then, slowly back up holding the device
as close to the surface as possible until the second tone can be
heard – this is the range at which to conduct the box search.
Holding the transceiver in exactly the same orientation and onto
the snow surface, walk a square (box) around the marked spot
(center) maintaining that range, until the distance indication
changes to show the signal has jumped to the second transmit-
ter. From there the second subject is located using a traditional
bracketing method. In case there is no second low point of
distance indication on the box, the second buried subject might
be below the first. Probe the surface of the micro box with full
probe length.
