Eclipse Cable System
The Eclipse cable system is designed specifically for bores that:
¾ Have depths in excess of 50 ft (15.2 m).
¾ Have lengths that require several days to drill.
¾ Do not allow walkover locating.
¾ Are in high-interference areas.
The depth and locating ranges of the Eclipse cable system are both approximately 80 ft (24.4 m). These
ranges are dependent upon environmental conditions and characteristics of the housing. Depth and
lateral location information is tracked using the Eclipse receiver.
Cable System Components
The Eclipse cable system consists of four main components (cable transmitter, power supply, remote
display, and cable extraction/insertion tool) and a power source, which are described below.
Eclipse Cable Transmitter – This transmitter measures 19.00 in. (482.6 mm) in length by 1.25 in. (31.8
mm) in diameter. It requires a special rear-load housing with an end plug that allows the transmitter’s
cable to exit the housing. The end plug requires a compression fitting to seal the transmitter from the
drilling fluid. The housing must also have at least three slots equally spaced around the circumference of
the transmitter that
measure 9.0 in. (229
mm) in length and at
least 1/16 or 0.0625 in.
(1.6 mm) in width (see
figure) for proper sig-
nal emission.
