Used to observe underwater, helping divers can clearly see the scenery below. Good glasses are glasses with a wide view, clear look, soft sugars, deep diving without water, long deterioration. Clear glass, good impact resistance.
Maneuver quickly under water, when swimming far, deep dive.
When swimming is partly due to the effect of water resistance plus flow, if the
propeller is not taken, it will quickly lose strength. Choose the propeller to
fit your legs, too tight to cause leg pain or too wide, you can lose your legs.
A good propeller is a propeller that must have good ductility, durability, a
high displacement force, and a comfortable swimming position.
Use to keep warm and protect scratched when bumps or bites
occur. Selecting a wetsuit so that it fits well, not too wide, will cram all
into and circulate, causing the body to lose heat. If too tight, it will be
difficult to manipulate and difficult to circulate blood.
Gloves, socks, hoods, pressure gauges, heart rate, etc. These
items function to keep warm, scratch-resistant, etc.
There are 3 types of diving suit as follows.
Usually made of nylon. This suit protects the entire body
from scratches but is poorly insulated and should only be worn in warm water.
It also helps to protect against the sun when you get out of the water.
This is a common type, There are many models and different
thicknesses so the wet diving suit has the proper insulation ability both in
cold water of 10 degrees C and warm water of 30 degrees Celsius.
Dry diving suit isolates you from water making you dry. It is the warmest diving suit, used only for diving under cold water below 10 degrees Celsius.
