HI Daniel,
We had a similar problem on a mine called Speedwell in the UK. Our problem,
we found out, was that we had very few points in a straight line of passage
leading to a middle entrance of the system. The model we were using had
quite long lengths for this part of the survey, so when

I tested this, and can confirm that Therion can indeed work at

Interesting. How are you fixing only the easting and northing, without
fixing the altitude? (Or are
Hi,
We are facing a problem with Therion and fixed points obtained by radiolocation.
This is the survey of a very long siphon taken with the SeaCraft ENC3 tool.
There are many many stations saved automatically with the device.
We fixed two points determined by radiolocation, one at the beginning
