The next option is setting the level of

conservatism for the decompression model. The original

software has eleven levels of conservatism, setting “1”

being the least conservative and setting “11” being the

most conservative. The GF-low and GF-high limits are

decreased equally with increasing level of conservatism

forcing deeper stop depths and lower allowed limits of

inert gas loading. Starting with version 4.5, true gradient factors are employed with

separate limits determining where the stops begin and when to proceed to the next level.

There are now five preprogrammed gradient factor sets and one user programmable

setting. The selected gradient factor can be changed during the dive allowing full control

over the dive profile. The user programmable selection can even be reprogrammed while

in dive mode.

Changing the conservatism requires scrolling the past the set-point selections until

the “OPT” screen is displayed then selecting, scroll past the “Define Gas” until

“Concervatism” is displayed. Press the right button to select, The original software will

now allowing through 11 levels without any additional information. Starting with version

4.5 there are now 6 selections each will display the

associted GF-Low and GF-High settings associated

with the selection. The conservatism level is selected

with the right button then must be confirmed. All

confirmations on the HammerHead are done purposedly

with the left button selecting “Yes” to prevent

accidental confirmations due to double key presses.
