NRU-1C Field Use
Laying Out
• The NRU should be placed as close to the receiver point pre-plot position or surveyed flag as
possible.
• The NRU can be planted by using the ADS (Automated Deployment System), a manual
deployment tool, or a powered deployment tool.
o All methods solution a hole in the ground that perfectly fits the NRU lower end for
excellent EarthGrip coupling.
o The ADS will automatically plant an NRU.
o With the manual deployment tool, the NRU will need to be placed in the hole by hand
and the top of the NRU stepped on with a foot to secure the plant. (Do not stomp on the
NRU as that may cause foot or leg injury).
o Depending on how hard the earth is, a combination of powered and manual
deployment tool can be utilized. Drill a pilot hole with the powered deployment tool,
then solution the hole with the manual deployment tool. Alternatively, solution the hole
with the powered deployment tool alone.
