Ok, you’ve found that prized perfect unbroken port hole. Now, how do you bring
it to the surface? Why with a lift bag of course! It is considered very unsafe
to use your own personal buoyancy devices to provide the extra lift you need
while carrying a heavy object. Lift bags are the safe way to do this, plus they
make your work much easier. In addition to lifting objects, a lift bag in the
hands of a properly trained person can also be utilized as a back up personal
buoyancy device. Most divers carry at least one lift bag with them at all times.
After all, you never know when treasure will pop up.
