This program is designed to provide Sport Divers with a safer than air breathing medium for enjoying dives in the 40 to 130fsw depth ranges. The diver may elect to dive the “mix” on EANx tables, or dive conservatively using air dive computers or air tables.
• Must be a qualified Open Water Diver
• Must be a minimum of 15 years of age
• Program covers all EANx mixes from 21% to a maximum of 40% oxygen emphasizing the use of EAN 32 and EAN 36%.
• It is recommended that all divers perform two dives on an EANx mixture between 24 and 40% oxygen.
• Upon completion of the lecture portion and passing the written exam the EANx Diver card is issued.
• Student must have the Nitrox Training Manual
• Complete a liability release
• Complete medical statement, if in doubt requires medical examination by hyperbaric physician.
• Complete the financial obligation resulting in his/her training. Refer to price list.
• Instructor is required to fill out the student performance track sheet.
• Lectures can be done during evening hours after diving operations or implemented during classroom sessions of an open water or cavern diving course. Training dives are optional so people could be done as soon as you are done with lectures and the student passes the exam.
• Maximum Po2 1.4 in bottom mixes.
• No-decompression diving.
• No dives deeper then 130ft-39mts.
• Minimum surface interval 30 minutes, more if possible.
• A sufficient quantity of gas will be carried by the diver to allow completion of the dive time requirements incorporating the correct gas is a management rule.
• A primary gas supply systems featuring an alternate second stage or alternate breathing source.
• A quick release weight system.
• Submersible pressure gauge.
• Buoyancy control device.
• Mask, fins and snorkel.
• Means of monitoring depth and bottom time.
• Submersible dive table must be used as back up to a dive computer or for control of the dive.
• Appropriate exposure suit for the environment in which the diver is being trained.
• Slate and pencil or wet notes
• Tanks must be labeled; the labels must clearly identify the MOD and oxygen content of the mixture.
• Cutting tool.
• Surface alert device.
• Equipment is to be configured in a neat low-drag manner.
• No dives may be conducted to depths greater than the student’s previous qualification, or a maximum of 130fsw.
• Appropriate safety decompression stops must be performed.
Water Skills Development
• If OW dives are made, the instructor may elect to use the applicable EANx tables or plan the dives as if air were used, thus capitalizing on the maximum physiological safety factor.
• If OW dives are made, students must develop a dive plan appropriate for the mixes being used on both dives.
Approximately 2-3 hours of lecture including:
• Introduction to EANx diving
• What is Nitrox and History
• Physiological implications of oxygen
• Partial pressure considerations and CNS oxygen toxicity
• Physics for EANx divers
• Daltons law, oxygen exposure, MOD calculation, best mix calculation
• EANx dive tables
• EAD concept, Nitrox tables
• Operational implications of oxygen and oxygen safety
• EANx advantages, blending methods of EAN, Equipment considerations.
• Written exam has to be scored 80% or better. If training dives are to be done we recommend that the exam to be completed before the last training dive if possible.
