Who disagrees with DIR and why?

scubadog76, you probably had to perform the gear exchange in your DM class. But you were also faced with additional task loading. It is likely that one buddy had to remove their mask and their reg at the same time. That is when the true panic sets in (fun to watch!). Your scenario is very different than switching from a primary to a backup reg.

You may not feel comfortable switching regs in your mouth. That will come with additional experience and training. The most important thing is to save your buddy.

If/when you decide to take more technical courses you will have to adapt.
