Surveying Techniques & Tips
The antennas can be held at a constant separation by using a rope tied between them (Figure
11-2). Antennas should not move while data are being collected, as indicated by the duration of
the beeping tone. Keeping the antennas static assures the highest quality data. When the beep
stops, the antennas can be moved to their next position in preparation for the next trace.

Fibre optic cables can be broken or damaged if care is not taken. The most common breakage
point is right at the connectors when the cables are snagged or pulled hard. Protect the fibre
optic cables by making a strain relief. Take an extra loop of cable and fix it to the handle using a
Velcro strap. That way, if the cable gets pulled, the strain is taken up by the strap and not the
cable.
