Before you start your diving activities and using a snorkel for the first time, there are some important tips and notions which you must learn and take into account. When done properly and following some main guidelines, diving and wearing a snorkel can be a great and very enjoyable activity, but if it is done without following the basics problems might arouse and it might end up being a headache rather than gratifying.
Wetsuits are meant to keep divers warm by giving them thermal protection. There are some important guidelines which a diver should learn regarding the wetsuit he might acquire and use. First of all, it is important to know that they are usually made from neoprene; most of the times open cell neoprene.

A magnetic compass is an indispensable device which divers should always carry and be able to consult while they dive. The compass might make the difference for a lost diver allowing him to find the shore, which he couldn't do without it. Having a magnetic compass is crucial at the moment of wishing to know where we are while being at the water.
Dalton's law refers to the effects which partial pressure might have on divers. This law says that the pressure of mixed gases is equal to the pressure produced by the individual gas. It can also be explained by saying that the total pressure of a mixture of gases equals the sum of the partial pressures of gases which are part of it.
Decompression is necessary whenever a diver wishes to dive in depths which go under the 130 feet. If a diver tries to go deeper than 130 feet into the water without following decompression procedures he would instantly notice that his air starts running low and would feel the effects of pressure in his body.
Diving in a current implies a higher amount of difficulty and danger than regular diving, but this can be avoided if the diver knows how to properly do it by being trained for it as well as by learning some important guidelines. Although some rules regarding diving in a current are given in most diving training schools, if you are going to dive in a current you should also receive specialized training for it.
Skin squeeze is one of the barotrauma problems which divers can suffer due to the pressure factors involved in the practice of the sport.

Barotraumas include problems such as external, inner and middle ear squeeze, eye squeeze, skin squeeze, sinus squeeze and lung squeeze.
