I'm going to the red sea in Egypt next week and want to bring my own gear, I'm from Canada and all my regs are regular yokes, do the tanks in the red sea have primarily DIN or both????? will it be a problem to use my yoke style first stage>>>

The best way to find out exactly what equipent you'll need is to contact the operations you'll be diving with. A quick email can help you plan ahead and save you alot of grief before yopu ever leave.
