This too is a myth.The donation process is well practised and very smooth
Without commenting on whether primary donate is better or worse … Almost all recreational agencies teach secondary donate. So secondary donate is the most commonly taught and practiced method. Again I do comment on whether it is better or worse.
Also, while many primary donate users have received high quality instruction from various Tec agencies, many also appear to be internet self taught with questionable levels of instruction, drills, knowledge and experience of using primary donate or a long hose configuration. See eg the thread below … (or the OP for that matter, since that was his first dive trip in long hose configuration).
