Spearfishing fins

Plastic, fibreglass or carbon spearfishing fins 

Blade material is the main decision and there are three trade-offs at play. 

Plastic blades are heavy, durable and cheap. They flex less per kick, which means less raw efficiency, but they tolerate impact with rock and kelp without cracking. Most Sydney spearos who dive kelp-heavy sites along the local coastline prefer plastic for exactly this reason. Plastic is the right first-fin choice for almost every beginner. 

Fibreglass blades sit in the middle. Lighter and more responsive than plastic, more durable than carbon, mid-range on price. They suit the intermediate spearo who has worn out a set of plastics and wants more power without the carbon premium. 

Carbon blades are the most efficient kick for the energy you put in, which matters when you are working a long surface interval cycle and need to conserve energy. They are also the most fragile and the most expensive. Carbon makes sense for the spearo who is regularly diving deeper, working longer cycles, and diving sites with less rock impact risk. 

Foot pocket fit matters as much as blade material. An oversized foot pocket robs power on every kick and a tight one gives you cramps after thirty minutes. Foot pockets are sized to take a wetsuit boot, not a bare foot, so size with the boot you actually dive in.
