Hey Tim,

Further to what Sam said I wouldn't count on a safety free diver diving to 30m to operate an FHOF solution to raise the diver from depth. That's a pretty stressful thing to do, no matter the skill or ability of the diver who is asked to make the dive. That a dive deep enough to cause complications if the safety diver is freaked out, nervous, scared or afraid of what might happen if he or she doesn't succeed.
