Two Masters !

Alan Crichton · 22nd September 2007, 11:41

When diving last weekend for the first time in 6 months, due to surgery not lack of intent, I settled down at a mere 20m and run through a few drills. All went fine then we started of across the coral reef looking for very specific reef critters to photograph. Anyway as we moved around about 60min into the dive I heard a double beep. Checked my handsets and voila both were masters ! Now we all know what heppens when you have more than one boss. The O2 injector had fired and I initially dropped the set point from 1.3 to 0.7 to see if that would close it - it did not even though both masters showed 0.7. Anyway I quickly switched of the real master , right had side, and then switched it back on and it realised it was a slave. Switching of the left hand master immediately made the right hand the new master as it should. Switched the left hand head back on and it went to slave. No problem finished the dive.

Anyone know why two masters can co-exists at the same time ?

I`ve had the same thing happen to me.

It`s allready been discussed in:

It`s caused by both handsets talking to the memory at the same time which confuses everything. Something that also goes wrong very frequently in automisation.
