My suggestion is to wait until your first class session and listen to your and try different gear and equipment! Most LDS will give their students a discount during the class and that way you can ask your instructor their opinion! Believe me they have one! They can explain the different masks, Fins, Snorkels, and other gear! But be aware the gear you learn in may not be the gear you decide to dive in in short time! Back inflation Vs Vest, a number of different wight belts styles, and regulators! I will tell you that in cold climates the most important piece of dive gear you can buy is a CUSTOM wet suit made to fit you! It will give you more freedom of movement, keep you warmer, and make you comfortable while your friends wish they had one as they turn blue! The suit will be your most important investment! It will allow you to dive all year and your equipment will not sit in the garage waiting for summer to arrive!
