I did the rescue diver course last May & I'm about 5'2", like many of you I was also the only female in the group. I broke my left wrist badly a year before & have next to no strength in that arm, I struggled with some parts of the course but on the whole it all went well. It's defintely one of those courses that everyone should consider doing at somepoint in their dive careers as it teaches you want to do when things go wrong which in turn will improve your diving.
Enjoy!
Enjoy!
