Grams 66
Setting your maximum depth trigger to
achieve 8 kilos (18 lbs) of lift is dependent
upon the number of grams of CO2 contained
within the cylinders. For exact information,
use the table at the right. For an
approximation, use the rules of thumb below:
For CO2 weights of 136 gms or less,
just
divide the total by 2 to arrive at a value in meters.
For example, if you are using two 38 gram
cylinders, you would add their weights together
and divide by two (38+38)/2 = 38 to arrive at the
depth providing 8 kilos (18 pounds) of lift. For
equal-weight cylinders use the weight of one
cylinder as the maximum depth in meters to
provide 8 kilos (18 pounds) of lift. Note the chart
at the right, where two 38 gram cylinders provide
18 kilos (18 pounds) of lift at 41 meters.
For CO2 weights of 136 gms or more,
add the
combined weights of the cylinders and divide by
two. Then add 10% of the combined weight for
the total depth in meters to provide 8 kilos (18
pounds) of lift. For example, with two 68 gram
CO2 cylinders, the combined weight of CO2 is
136 grams (2 x 68.) 10% of 136 is 14. Add 68
plus 14 to arrive at 82. See the lower arrow in the
chart to the right.
