Yes as Marwan says, speargun reels are not made to fight fish like you can do with angling/rod&line reels.

Our reels are very simple devices, just meant to endure the initial reaction of a fish: you give him line to prevent him breaking off when he initially tries to escape with all of his strenght. Then after, when his strenght diminishes due to pain, bleeding and vital organs damage, you simply go to retrieve it.

You use a reel for big fish, badly hit fish, or when you shot a fish while you're feediving very deep. In the last case, the reel will let you swim up your way to the surface without having to "lift" the fish with you. In this sense, it's also a safety device.

My suggestion is to keep your reel with a semi open friction (i.e. with a little drag) and then, eventually, open all the friction after shooting the fish.
