MOD is displayed in an alternate display window so you
can see by how much you have exceeded it. In addition,
the Galileo 3 will beep incessantly. Both the blinking of
the depth value and the beeping will continue for as
long as you stay deeper than the MOD.

Absolute Minimum Depth (AMD)
Ascending above the AMD may lead to sudden loss of
consciousness and death by drowning.
If you are using a hypoxic gas mix, it produces a high

Violating a mandatory decompression obligation may result
in severe injury or death.
