Hi! I bought a saftey sausage (about 4-5 ft) and thought it should be rather simple to figure out how to use it (and to find a proper user guide). Well, sorry if I am asking a stupid question, but I need some help. There are weights in the bottom and the only way to enter air is by pressing these weights apart, so that the sausage opens. If I shall fill this sausage with air when I am on the surface, should I take the regulator, hold it under the surface, free flow it into the sausage and fill it up? Or how do I do? My intension is not to fill it up when I am down there, it's going to be used in case I need it on the surface. Appreciate any help how to use it. Don't have to add that I am new to diving (AOW with 19 dives). I only dive with dive operators so far. But I thought I should be prepared anyway, you never know what can happen.
