Cromhall Diving Centre
Cromhall Quarry has 9.5 acres of water and is only 1.5 miles from J14 of the M5.
The slightly undulating rock bottom gives an ideal training depth of 17 metres. It slopes upwards to the former haul road entry, giving a shallow beach area allowing easy access and egress for entry-level dive trainees and rescue training.
At the north end of the quarry is a pontoon floating in 15 metres of water that has been specifically designed for ease of use by divers.
The former limestone quarry has filled naturally and the water quality meets EU bathing standards, with underwater visibility during March 2010 of up to 5 metres, which is expected to rise to 8-10 metres during the summer.

Nitrox/Trimix Continuous Blending
Cromhall Diving Centre is the UK representative for the LM-NT Continuous Process blending systems that supply pre-mixed low pressure O2/He to the compressor for direct filling of diving cylinders with Nitrox (max 40%) and Trimix.
The diving cylinders do not need to be oxygen cleaned to fill with this process and the system eliminates the risks of partial pressure blending.
