   Tropari - Setting Time



Hold the Tropari in your left hand.

Using the index finger and thumb of the right hand, gently move the knurled timing ring so that the setting mark on the ring turns to the left.

  Timing the Tropari  

Remember that the last ten minutes of the time set on the TROPARI  is  utilized for the locking cycle. If you have not reached your survey depth when only ten minutes are left, the survey will not give meaningful results if you continue to lower.
