IANTD &TDI NITROX DIVER: £245.00.2 Days

PURPOSE.


The purpose of both the IANTD and TDI course is to provide Sport Divers with a safer than air breathing medium for enjoying dives in the 12 to 39m depth ranges. The diver may elect to dive on EANx tables, or dive conservatively using air dive computers or air tables.
The programs cover the use of EANx mixes in the range of 21% to a maximum of 40%.

DSMB deployment

PREREQUISITES.

Must be qualified as an Open Water Diver.
Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 12 years of age for junior Diver qualification, or a minimum of 18 years of age without guardian approval.

PROGRAM CONTENT.

This is a 2 day course. Day 1 is spent completing lectures pertaining to the theory found in the IANTD / TDI EANx Diver Student Manual. This covers all EANx mixes from 21% to a maximum of 40% oxygen but emphasizes the use of EANx32 and EANx 36.

The 2 dives are instructor led and supervised but no in water skills take place other than DSMB deployment and bail out skills. Although aimed at divers using single cylinders in a no decompression environment, divers wishing to combine this course with an Introduction to Twin Set Diving could do so provided they meet the necessary prerequisites as regards number of dives and experience.

EQUIPMENT.

Dry suits recommended (semi-dry suits only suitable in the summer), mask, fins,
Weight belt
Regulator with Alternate 2nd stage (minimum), twin take offs recommended or Pony cylinder.
Dive timer / Nitrox Computer
BCD or wing if Twin set diving
Knife or Cutting tool.
Slate.
DSMB and reel with 50m line.

All equipment is available for hire at competitive rates if required.

IANTD ADVANCED NITROX DIVER: £350.00, 3 Days
OR TDI ADVANCED NITROX & DECO PROCEDURES COURSE: £450.00
. 4 Days

Both these popular entry level courses aim to introduce skills and procedures required throughout technical dive training, with each course building on previously learned skills. Divers are expected to perform these skills with increased mastery as they progress.

PURPOSE.

The purpose of either course is to introduce the use of twin sets and stage cylinders for decompression dives in the 40m range. Gases used are are up to EANx 40% in the twin sets (back gas) and up to 50% in the stage cylinder or up to 100% if taking the TDI route.

PREREQUISITES.

Must be qualified to Advanced Open Water Diver or equivalent and EANx Diver
Provide proof of a minimum of 15 logged dives.

Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 18 years of age without approval.
Although not a requirement students will benefit more during this course if they already have experience diving with a twin set and carrying a stage cylinder. ( See our Introduction to Twin Set Diving courses.)

PROGRAM CONTENT.

One day of theory is followed by a confined water skills session and then 2 or 3 days of diving, making between 4 & 6 dives to a maximum depth of 40m.
( We normally dive on wrecks in the 35m range on course.) We would strongly recommend you take the IANTD Advanced Recreational Trimix Course (see below) if you plan to make regular dives in the 35m-50m range.

Skills taught and practiced:

Gas shut downs
Gas sharing ascent
Stage cylinder removal and replacement
DSMB deployment
Deco gas switching
Swim techniques

EQUIPMENT.

Manifolded twin set in O2 service
7 Litre stage in O2 service
Primary and secondary regulators for the twin set (primary with a long hose 1.5 or 2 m)
Stage regulator in O2 service
2 timing devices / nitrox computers
50m reel and DSMB or lift bag.
Wing style BCD ( conventional BCD's are not recommended.)

N.B. This course is really not suitable for single cylinders. For redundancy and safety whilst diving to these depths a manifolded twin set is by far the best option. The gas duration of a single cylinder would probably not allow decompression diving.

 

IANTD ADVANCED RECREATIONAL TRIMIX DIVER: £499.00. 4 DAYS.

This course covers everything the IANTD Advanced Nitrox and TDI Advanced Nitrox & Deco Procedures course involves but with the use of Trimix.

PURPOSE.

This course is available for divers diving in the 30-50m range where air would usually be used but in order to reduce the effects of narcosis, weak Trimix mixes can be used. This promotes the IANTD philosophy of using the best gas for the depth of the dive.

PREREQUISITES.

Must be qualified as an IANTD Recreational Trimix Diver or Nitrox Diver and IANTD Deep Diver with proof of a minimum of 30 logged dives or sufficient experience to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.
Must be a minimum of 15 years of age with a parent or guardian authorization, or a minimum of 18 years of age without approval.

DSMB deployment

PROGRAM CONTENT.

Day one is spent covering the theory as outlined in the IANTD Advanced Recreational Trimix Diver Manual.
This program must include a minimum of 120 minutes of OW bottom time completed within 4 dives, 2 of which must be made to depths between 30m and 48m. All dives deeper than 24m must be made on Recreational Trimix mixtures. eg 30 / 25
Students are taught the use of Recreational Trimix mixtures from 28% to a maximum of 40% oxygen and with the helium content having an END no greater than 24m for diving. EANx mixtures of 1.5 PO2 oxygen should be used for safety on decompression stops.
Mandatory decompression stops are limited to a maximum of 15 minutes.

Skills taught and practiced:

Gas shut downs
Gas sharing ascent
Stage cylinder removal and replacement
DSMB deployment
Deco gas switching
Swim techniques
Remove and replace tanks and BCD at a depth greater than 6m
Remove and replace tanks and BCD at surface.
If entering the program based on previous experience, complete the IANTD Deep Diver water skills.

EQUIPMENT.

Manifolded twin set in O2 service
7 Litre stage in O2 service
Primary and secondary regulators for the twin set (primary with a long hose 1.5 or 2 m)
Stage regulator in O2 service
2 timing devices / nitrox computers
50m reel and DSMB or lift bag.
Wing style BCD as conventional BCD's are not recommended.
