... With regards to GEM and deep diving, so far we only have a recreational course. But we are actively working on the next level of training, and hope to have that available soon.
Yes, GEM as it stands right now, is designed for the recreational market. but yes, it did come from deep cave diving. We tweaked the unit to make it more appropriate for recreational diving; but in essence very little has changed.
Deep diving on the GEM involves gas switches and carrying various gases, as well as a true understanding of what happens when you dive a low nitrox mixture in a semi closed rebeather. this is why a training program is important. When this level of training is complete, we will have an annoucment.
If anyone has others questions for me, please let me know.
all the best,
