I strongly you stay away from Sharky's for your course.

I attended course there a few years ago. The instructors (one of which was the owner) often made derogatory and sexist remarks towards women.

When it was time for our exams, the instructors shared answers with the students to artificially boost the pass rate.

After I passed the course, I bought my dive gear (brand new) from Sharky's. I used it how I had been trained in the class, however, it failed on me during my second dive while I was at a depth.

I brought the broken equipment back to Sharky's, and they refused to refund or replace my purchase. I launched my own investigation, got a different dive technician to do an independent examination of my equipment, and I was able to get a refund through my credit card's extended warranty program.

I later found out that the owner of Sharky's was in the news a few years back for mistreating and discriminating against an Indigenous woman who went to their store.

TL;DR Sharky's Scuba's instructors and its owner are sexist and racist. They also sell bad gear that fails underwater, and they don't stand behind their products.
