crpntr133:I was taught to use my lungs to fine tune my bouyancy. I was also taught that the inflator button IS NOT an elevator button.
RIDIVER501:Not neccessarily true.
if you have done a proper bouyancy check at the surface. dumping any more led will cause you to be positive.
If you are at depth remember that your exposure suit will compress, thus changing your bouyancy characteristics slightly. (making you more negative)
What are the components of a divers bouyancy system.
1. BCD.
2. Lead
3. Exposure suit, if diving dry the dry suit is used inplace of the BCD at the bottom.
4. your lungs (for fine tuning)
if you are slightly heavy at the bottom,when you have already done a proper bouyancy check. you don;t need to remove lead you need to add another small burst for air or two to your BCD/Drysuit.
delaying an inhalation for a few seconds isn't harmful,
delaying an exhalation with a full breath can be fatal.
