Choosing fins are very much a preference thing, just like what colour or to have split or non-split fins. Some divers love split fins while some divers hate them. Personally I find split fins is great for going fast in a straight line, but not good when you want to turn and manoeuvre underwater. It's maybe something you would get used to after a while, but I just didn't get on with split fins at all.
Due to the design of split-fins, there is lesser resistance when you ‘scoop’ the water. For that reason, you will go faster and use less air. It’s best to use on flutter-kick and good for surface snorkelling too. Ladies love it because it’s less strenuous underwater.
So what fins to choose? For beginners, start with a non split-fins first. Once you improved your kicking style and leg muscles, borrow a pair of split-fins and try first before you buy it.
