6.8 Push rod system (optional)
The push rod system is used to push the Boretrak2 probe during horizontal or uphole deployments. It is also suitable
for use in shallow, downhole deployments when the hole is not steep enough for gravity to pull the probe down the
hole under its own weight.
55 m of push rod is spooled in a cage held in a metal frame. The push rod is made of alkali-free fibreglass and high-
quality resin for flexibility and tensile strength. The exterior layer is covered with high density UV-resistant
polyethylene.
The push rod is marked with nodules at one metre intervals. These nodules aid accurate deployment of the
