APPENDIX H.  Spiral and Compass Probe Operation 

 

 

The GK-604D IRA supports two different compass probes: 

1)

 

 The analog Spiral Indicator Probe (6005-3), requiring the GK-604-3 Analog Reel 
System or the GK-604-4 Interface Module. 

2)

 

The digital Inclinometer/Compass Probe (6100D-X, Firmware Version V2.5), 
requiring a GK-604D-X Digital Reel System with a firmware version of V2.5 or 
higher. 

While both probes can provide spiral survey data, there are significant differences in 
their features and operation.  The two probes are individually described in the sections 
that follow.  

H.1 Spiral Indicator Probe (6005-3) 

 

The Spiral Indicator Probe (see Figure 84) connects to a GK-604-3 Analog Reel 

System (see Figure 6) or the GK-604-4 Interface Module (see Figure 5). In general, 

operation of the Spiral probe is similar to the standard 6100-1X probe with a few 

exceptions. The steps below provide basic instruction on how to perform a spiral 

survey:
