scbababe:I could!.. First,Give your OK signal. Do however make sure the OK signal is returned. Once this is accomplished, reach for your sausage, unwrap and hold it upwright (ask for assistance and oral inflate!!)
If there is any doubt or significant distance between you, deploy your sausage this will increase your visibility and makes you easier to spot. Of course avoid waiving it, for this means you are in distress. Although sausages are not your only option, they are a starting point, and are certainly required. Before you depart on your next adventure, check your equipment and your dive destination, and remeber practice, practice practice...
Whew! The only thing I can add is that I'll be keeping my sausage as upright as possible! That oral inflation really helps keep it nicely rigid.
And, of course, the more upright it is, the better it serves its purpose...
