2.
The design is for a borehole condition monitor. The monitor has an
elongate body with an obliquely truncated end, allowing the body to
be pegged into the ground in the vicinity of a borehole drilled for
blasting. A warning light is provided on a front face of the body.
The warning light is activated by an activation tab which projects
from an elongate transverse slot when the monitor is in an
inactivated condition.
The broken line showing of structural features is included for the
purpose of illustrating non-claimed subject matter and forms no
part of the claimed design.
