NOTE
: The SST transmitter must be kept at least 5 ft (1.5 m) away from all magnets including the
remote display, which has a magnetic mount that will damage the transmitter. A special non-
magnetic housing is required.
The non-magnetic housing for the SST transmitter must be a rear-load housing. To prevent overheating
and for optimum performance, the transmitter must be installed correctly in the housing. An extraction/-
insertion tool is provided with the SST transmitter for use in properly installing it into and removing it from
the housing. Installation instructions are provided in the
System
Operating Instructions
section.
It is critical that the slots in the drill housing meet minimum length and width requirements and be
correctly positioned. DCI recommends at least three slots equally spaced around the circumference of the
housing. Each slot must be at least 1/16 or 0.0625 in. (1.6 mm) wide. For accuracy, slot measurements
must be taken from the inside of the housing. The SST transmitter, which is 24 in. (60.96 cm) long,
requires slots in the housing that are at least 9 in. (22.9 cm) long and begin at least 8.5 in. (21.6 cm) from
the front end of the transmitter, as shown below.

F5 SST Receiver
The F5 SST receiver is an F5 receiver that has been upgraded with the SST capability. The receiver is
used to locate the SST transmitter when walkover locating is possible and to confirm depth readings and
other transmitter data. The locating procedure for the SST is the same as that for the standard F5 locating
system, with simple two-button (trigger and toggle switch) operation.
