A blade is a crucial item of safety and security tools used primarily to reduce guidelines, free complications, as well as repair service, harmed lines. Because the blade is made use of to cut standards, a tiny sharp knife placed on the forearm where it is convenient is more valuable than a bigger knife endured the leg. If you already use a large blade then it should be worn where it will not easily obtain twisted. Wearing the knife inside a customized suit pocket created to hold it is more suitable. Alternate sites include the BC tube, container waist strap, or shoulder. The beyond your leg is the least preferable area for your blade.
Some divers choose to carry two blades which are placed so that they can reach one with either hand in the occasion that the other is inhabited. While many scuba divers utilize either a solitary 71.2- or 80-cubic-foot container, tulum caverns divers have made use of most all kinds and also dimensions of containers efficiently. For factors that will certainly become clear later, it is best that all dive employees make use of the same size scuba cylinder which all the cylinders are filled to approximately the same atmospheric pressure (but not much less than 2000 pigs before beginning a dive).
By adhering to the above recommendations, air preparation for the dive is considerably streamlined. Diving cylindrical tubes are typically fitted either with a K-valve, which has no get, or a J-valve, which keeps a little book air supply. However, the quantity of air book provided by a J-valve is insufficient for safe cavern diving. Instead you must rely upon your stress gauge to make sure that you have adequate air to safely exit the cavern and also to manage any type of emergency situation that might create. If you are geared up with a J-valve, then the valve needs to be put in the triggered position, not the reserve placement. Some treatment is required to insure that the Jvalve device is safeguarded to avoid developing a potential line trap. Many cavern divers discover that air duct tape wrapped around the shutoff suffices.
The J-valve pull pole should be removed and also stowed ashore to stay clear of one more possible line trap. Although not required for tulum cave diving, numerous cavern divers think about the dual-valve manifold to be an also better different than either a K- or J-valve. They supply two independent air electrical outlets which permit two different regulators to be attached to the valve. Needs to one regulatory authority fail, it can be shut off leaving the whole continuing to be air supply offered with the other.
