The third and final training dive of the Self-Reliant Diver Course was essentially a dive planned and led by me. I choose the dive profile and the route taken then led the dive as if I were solo. I chose a max depth of 10 metres and a max time of 35 minutes with a turn around time limit of 17.5 minutes or 133 bar, whichever came first. That profile didn't require as much air as the second dive of the course so I only had to bring the little 2.7 litre pony bottle with me.

But the third dive still had a number of objectives:

1. Write the depth and time on a slate at 20 bar intervals
2. Turn around at a predetermined time limit or air pressure limit
3. Navigate the entire dive without assistance
4. Switch to the redundant air supply
5. Deploy a surface marker buoy (SMB) on reel with a line while breathing off of the redundant air supply
6. Do all of the above within the planned dive profile 

I used the same slate as the second dive to write the depth and time since the slate has multiple "pages".

Navigation was a combination of compass work and natural navigation. I chose to dive directly away from the anchor point at the weed line due north for 5 minutes, then west for 10 minutes, back south for 5 minutes, and finally follow the weed line east until I hit the anchor point. The dive went pretty much according to plan and we arrived right back at the anchor point.

The anchor point was only 5 metres deep so we swam out a bit to get a little more depth before running through the final objectives. I switched over to my redundant air supply without issue and deployed my SMB without incident. 3 minutes later we were back on the surface with a total bottom time of 34 minutes.

All of the objectives were completed within the dive profile and I've passed the course! Many thanks to my instructor Sue at Dive Wellington for all of her training and patience with me.
