NRU-1C-KCK Description
• The KCK model of the NRU is the same as the NRU-1C discussed in the last chapter, except there
is no geophone element embedded in the case.
• The KCK model has an industry standard KCK style 2 pin threaded watertight connector built into
the case in the place of the geophone element.

• The electronics boards and specifications are the same as the NRU-1C, except for the geophone.
• This model allows users to connect their own geophone string or hydrophone to the NRU.
• The KCK model can also be used to record the auxiliary signals from the source encoder unit, i.e.
Timebreak, Pilot, etc.…….
• This model can also be used in the field with the sources to capture source signals. Vibrator
hardwires can be recorded as well as the signals needed for HFVS or other specialized Vibroseis
operations that require the capture of source signals.
• Commissioning, uploading and charging procedures are the same as for the NRU-1C nodes.
• Deployment, Auto-Deploy and Un-Deployment are all the same as the NRU-1C, except that
when bumping a KCK unit that is in Auto-Deploy mode the user may lay the unit on its side, after
it has started searching for GPS.
