That was pretty ridiculous. But it is good to show how things can turn ugly quick.
Shall we go over it?
The shot placement was bad.. Shooting an AJ in the gill plate should not be assumed to kill the fish. You had all the time in the world to place a perfect shot and your screwed it up (I've done that a 1000 times; but you should expect to pay consequences when you perform poorly).
then what do you do after the shot? Take wraps of line around your hand with 3-400 lb monofilament? what if a shark zooms in and grabs the fish? You are going for a ride.. I try to avoid taking wraps of line around my hands.
Those fish typically will be very quiet after you take the shot if you are gentle. Immediately after the shot, I think I would have been gently swimming away from the leg of the rig so the fish does not have enough line to wrap around it. when there is stuff to get entangled in, I will try to get the fish away from it, so I have room to let it swim (when it wakes up after the shot). Do not horse AJ's until you have to, you can often finesse them into position if you are gentle.
You also have one hand on the line and one on the gun after the shot. Why? What good does that do? If you are gonna grab the fish, then drop the gun and let it float above you and swim down the line as you go hand over hand down the line to the fish. Swimming DOWN will put the floating gun well above your head and reduce the chance of entanglement.
Grabbing it with two hands and holding the chin? Who ever taught you that? What the hell were you gonna do with both hands on the chin? You should have used one hand to try to grab the gills, then use a knife to kill the fish or use a stringer. Holding a large struggling fish in front of you is not a good idea.
With a large powerful fish like that i try to get him under my arm pit, with the head forward. He may pull me around but it will mostly be horizontal and more importantly he can not easily hurt me. With that fish in your face like that, he can break your front teeth (mine are still chipped), knock your reg out, and knock you mask off, then swim around you and wrap your arms to your sides with the shooting line..all in about 0.3 seconds (Believe me, I learn this stuff the hard way).
If you have the fish under your arm, the tail will be behind you back, not smashing your teeth - he will beat your ribs with his tail, but you can crush down on him with your arm and this is uncomfortable but he can't really hurt you too much like that. You can ride the fish for a while like this and you have some control and can steer yourself as he propels you forward or more likely in small circles.
Then you get a reg knocked out, you drop the fish and then your buddy offers an inflator - air 2 for you to use?
He should have stuffed your reg back in your mouth if you were too messed up or tangled to do so. Next best option would be to stuff your octopus in your mouth, next option should have been for him to stuff his primary in your mouth...sticking his inflator in your mouth is "not how it works".
And while I am on a roll here...
Get rid of those ridiculous split fins! If you are gonna hunt big strong fish, get some fins that will allow you to really apply pressure on the fish. . Most serious guys will use freedive fins..
I enjoyed the video, but getting your regulator knocked out of your mouth for 5 seconds should not be considered: "almost killing you"...
