This situation of safety must be replicated during spearfishing trips, Therefore it is highly recommended not to go out at Sea alone. Underwater fishing in fact would need to be accompanied by a second person with the same technical skills (able to reach the same depth).
Unfortunately due to the scarcity of prey, or to spice up the joke, even if you fish in pairs, We tend to scan various areas of seabed neglecting this aspect of safety.

The rule more effective would be to fishing in pairs, both in the water and alternately one of two supervising l ’ more from the surface, ready to intervene in case of problems.

Remember that no arrest warrants the reduction of safety parameters, also why is never useful to extend beyond the due time of apnea and go beyond the depth physically reached safely.


To maintain high security parameters a simple but effective trick is to adopt in a belt releasable weight (safety buoy). The burden in question will be part of the original balance of sub, but in the event of difficulties can be quickly abandoned to allow a faster.

On the market you can find (or can be made by hand) versions with line recuperaile.

A ’ other question stems on the position of the diving ’ mouthpiece during the. Many instructors and experts suggest sub remove the mouthpiece during the dive ’ so you don't have a direct access to water via d ’ lungs in case of anoxic syncope or loss of consciousness.

Direct experiences of other divers and free divers recount rather than have blacked out during an ascent as a result of prolonged apnea and being awakened by breathing through the mouthpiece that had kept in his mouth.
