When were underwater i generally dont hit them untill after the quota of crays. See them all the time there messy and leave shells everywhere. stingrays seals and dolphins smell occy a mile away ! Having a hungry stingray/seal tryn to dry hump you all the way back to the boat isnt fun.
There pretty powerful i stabbed a big one in 12 metres with a 900 speargun It almost took out of my hands untill i discharged it.
Baksey Youve done it before !

lol we only use solid fiberglass gidgies Use locktite on the screw so you can do the twist ! . ! if you dont get a head shot first and they dig in there hard to get alot of them are that smart they have multiple exit strategy's
