Good luck with this i would be interested to see how you go. I had a crack at getting one one day and it ended up holding onto me and i had to get my dive knife and chop a couple of tenticals off. Have fun but please be extra carefull and never try if u dont have a knife handy
I never dive without a knife. Seems dangerous to go out in the ocean with float lines and spear rigging and all the rest of the awesomeness that we enjoy and not bring a knife.
I'd like to hear more about how you got snagged by the octo -- did you end up killing it or did it escape after the tentacle chopping?
