Another Round up of Divemaster Course

DAN Oxygen First Aid for Scuba Diving Injuries - 1 Day course & Exam

This course is specifically designed to educate divers to recognise possible scuba diving injuries and to provide emergency oxygen first aid.
Topics covered: Respiration, Circulation, Heart, Blood vessels, Blood, Gas exchange. Diving injuries such as DCI (Decompression Illness) AGE Srterial Gas Embolism & DCS (Decompression Sickness) as well as different delivery systems and set ups. I'd suggest this course to anyone.

Open Water Diver Assist - 3 Days

Day 1 - My first assist as a DMT . I didn't have to attend the mornings classroom theory but met up with the 6 open water students after lunch.
My role was to assist the instructor with the logistics, predive set up of equipment for each the students, supervise student divers not receiving the immediate attention of the instructor, assist with any learning difficulties, respond to or prevent diver problems as they occur. Their first session was in the pool which was very busy & murky, watching them going through multiple skills for 2-3 hours or so and finishing the day very wrinkly and cold.

Day 2 - Met up with students for their first dive in the sea. I supervised skills as the instructor was doing skills one on one. A couple had problems with mask clearance and their buoancy but nothing major. The second dive of the day was much better, longer dive, students pretty controlled but very messy at the 3 min 5m safety stop. On board I had to do a dive breifing which turned out ok.

Day 3 - 7am start. The students had just 2 more dives to complete to be certified. First dive of the day was pretty good. Only had to tell a couple of students to watch their buoyancy and it's funny to watch some swim with their arms but will disappear with time and once they've done a few more dives. All in all it was a good dive until it came to the safety stop they were all over the place. 2nd dive everyone seemed more controlled, all managed to complete there skills sucessfully and safety stop very well. So another 6 divers on the planet.

Advanced Open Water Assist - 2 Days

Day 1 - 3 Dives of which one is a Night dive - Covering navigation on land and underwater. This is a much more stress free assist. Just need to help suspervise them on their navigation and lead them on a short dive as the end of each session. My experience was good, managed to get them back to the boat within meters and point out quite a few fish to them. The night dive I just followed at the back keeping an eye on the students just incase anything went awry.
Day 2 - 2 dives, one of which was a Deep dive of 30 meters and the other a Naturalist dive. On the deep dive the instructor found a sandy area where he played scissor, stone paper ..this is done to see if anyone has any narcosis ..if they had, then they probably wouldnt be able to deep dive as narcosis strongly affects diver performance, impairing ability to concentrate and observe accurately. Divers have reported visual and auditory hallucinations, dizziness, paranoia and depression.
The 2nd dive, Underwater Naturalist, the students had to look out and identify fish.
