Decompression Procedures Diver

Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like?

After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

Who this course is for:

• The certified Advanced Diver looking to expand their knowledge of decompression theory and diving techniques
• The certified Advanced Diver who is interested in extending their bottom time
