Spearfishing a large Camouflaged Sleeping Dusky grouper

I am sure everyone would love to know more about this video, I know I would.

Where and when did you take this video? Were you on scuba or free diving? What kind of depth and water temp, etc.

I don't think too many of us here spearfish, so any info on that is going to be very useful to us.

Personally I have a pole spear, but have not really had a chance to use it. I recently moved to the shore, so I think things are going to change this summer. I know we have a lot of fluke and flounder around here.
