- I'm a Fish!
Ok. I have a question. In spearfishing, if the gun is already loaded, all the diver has to do is pull the trigger (at the right fish and size of course). With a pole spear doesn't the diver have to pull a band like a sling shot? And, wouldn't that take more effort as far as bouyancy control goes?
Yes, the person using a pole spear would have to stretch the band in order to take a shot. As far as bouyancy control it will only have an effect by taking the divers concentration off of diving and onto the shot.
Having a diver concentrating on spearing, or photography, is not a bad thing. That is as long as the diver in question is first a competent diver. Sometimes when I'm shooting pictures I may either sink a little or rise up a little while I am concentrating on a shot. From experience at diving I sense this and compensate without loosing my ability to take the picture.
Without the competence that comes with experience, a newer diver my not notice even drastic changes in depth. They may rise up to the point where the air volume in their BCD starts making them rise faster, or they may sink down and end up on the coral. I am not saying that this will happen. It is just more likely to happen to a new diver when they become distracted.
If the new diver is competent in the water with bouyancy, and situational awareness, then it might be safe to try spear fishing. Like the previous posters I would suggest trying it in a controlled environment first.
