I had for a couple of years spearin the flats for mullet and sheephead. My question is will this gun be enough to spear grouper? I am relatively new to the sport and was just curious of veteran opinions. thanks!

Yes, especially in low viz situations.

Absolutely!

is it because of the speed of the shaft? for low viz shooting it is better? just curious. thanks guys. made me more confident out there to shoot grouper in hogs!
