Decompression Procedures Coaching

The end of three days of Decompression Procedures coaching resulted in a good long dive at Vobster Quay. People criticise using inland quarries for diving, however, in my personal experience, I believe that using an inland quarry for diver training is a great facility, allowing for controlled development in usually a controlled environment. I doContinue reading “Decompression Procedures Coaching”

Diving with a Stage

The second day at Vobster Quay has been a good one whilst we develop diving with a Stage. We started with the introduction of a decompression stage to enable the diver to accelerate their decompression penalty by using a richer oxygen mix, which in turn helps expel the Nitrogen from the body. The dive wentContinue reading “Diving with a Stage”

Twinset Coaching

Today I’ve been back at Vobster Quay diving centre running a twinset coaching course. The aim of the course is to introduce an existing twinset diver to the skills and drills of shutdowns and isolation. It’s something that I find a lot when a diver wants to develop their diving, carry more gas and stayContinue reading “Twinset Coaching”

We started the day talking through cylinder setup, analysing, labelling, deployment and re-stowing it. This was a good session where if weContinue reading “Accelerated decompression procedures course day1”

Buoyancy and Trim Workshop

Today I’ve been back at Vobster Quay inland dive centre teaching a Buoyancy and trim workshop for BSAC.

This can be due to overweighting, finning whenContinue reading “Buoyancy and Trim Workshop”

Decompression Procedures course at Vobster

Today we started a BSAC accelerated decompression procedure course at Vobster Quay dive centre. I’ve got two students who are dive fit and competent divers. Also joined by regional coach Jon Hudson who’s starting his instructor training with me. The first day is always a skills circuit, and today we spent 75minutes checking and workingContinue reading “Decompression Procedures course at Vobster”

Diving Wastwater – England’s Deepest Lake

Today we are Diving Wastwater! We were greeted with a stunning morning at Turners Hall campsite. Following a brew, we packed up and headed off to Wastwater, stopping briefly at The Sawmill Cafe for some very tasty bacon baps. Arriving at the lake, Dan and I met up with Mark and Yasmin. We had aContinue reading “Diving Wastwater – England’s Deepest Lake”
