I would recommend you get yor mask at least and a snorkel. Dive shops will let you try the gear out in a pool first to make sure you like it. If they will not do that dont buy from them. If you can bring your own fins I would but if space is a problem just go with a mask and snorkel. My shop gives you a good dealif you buy all three together. Also check out the shop you will renting stuff from because some places rent junk. So be careful,it can ruin a dive if your gear is junk.DIVE SAFE AND HAVE FUN
