This Lionfish Slayer is awesome, easy to use, and keeps you away from those pesky Lionfish spines! It is very fast to re-load – just pull back and repeat. I’ve slaughtered a whole bunch of them. It is small, out of the way when carrying, and the thumb twist makes it easy to fire. With regards to the material, it is made from a durable, non-corrosive, very high quality stainless steel that is salt, sand, reef and UV Ray resistant. This product is going to be around for a while.
