Hey, for Sargo - you have to ambush them, waiting for as long as you can, hidden in rocks/kelp, where they usually hide. In the Med you would have to dive to seven meters at least or so and hold your breath for more than minute down to get them. Sometimes, if cracks between stones are wide enough you can try to detect them in their hideaways, but usually they hide in such narrow passages, that it is hard to get them in the Med.
Where do you spearfish in Egypt, may I ask?
