Welcome Griffin.

On the contrary it's a very good thing you stated your age. You seem like a mature young man. But if you weren't, it would be easier to deal with taking your age into consideration, than trying to figure out if I'm dealing with a stupid adult.

Anyways soak up what we have to offer, put it into practice, and you'll forget about your scuba gear in no time

I don't think it's so much making known the conditions on a given day that concern these guys. Just funneling people to their now scarce spots period.

Steven, I'm not getting what you're saying here.

I'm open to this kind of input. The future moderators of the California section, who will be in tune with your local issues, will be in a position to educate and enforce rules we establish to protect this information.

Rick, it's a good question that you brought up, I don't think it's been discussed at length here before.

I spit the snorkel out on every dive. I do this by pushing on the mouth piece with my tongue, so I don't have to reach for it. The number one reason for me is that it's easier to take the first breath on surfacting, and consequent recovery breaths, without a snorkel. I also find I use up less energy when I'm not making an effort to keep the snorkel in my mouth, it does require a small effort. The snorkel flopping around has never been an issue for me. One option is tucking it under the mask strap, this eliminates any movement but the twisting in and out of the mouth. The whole process is almost automatic, I don't waste energy thinking about the steps.

When diving on a shallow fish flooding the snorkel eliminates the bubble noise which may spook the fish.

Mike, you should also try craigslist if you haven't already. This kind of item moves quickly there I imagine.

Really nice pics. Welcome Daniel.

The intros are getting hard to beat

I've had cobia and barracuda do this at me. I can't be sure of what it means because the fish didn't look ready to follow up on the threat, if that's what it was. But it did feel like "get outta' here".

Nice intro. Welcome to the forum Jay.

Welcome to the forum Chris. That was an interesting read.

Very nice fish. Welcome.

Suggestions noted. There will not be subsections at this time. If someone wants to raise the issue again in the future feel free to resurrect this thread.

Thanks Don.

In this case I'm not clear on what needs to be reamed with this pole spear.

What is reaming Mike? Is it reducing the outer diameter of a pipe in a stepped fashion, so it can slide into another section of pipe?

yep

These are my preferred powerheads http://www.freedivingspearfish…12-slip-on-powerhead.html

Do fish produce adrenaline? Do fish have an adrenal gland?

In the case of a mammal producing adrenaline, is saltwater a medium that allows sensing of the presence of adrenaline? If so how fast? Faster than visual signals perceived by a shark that would indicate to it whether it's dealing with prey?

If adrenaline is a hormone that is particular to land animals, is a shark, an animal designed to function in a marine environment, even capable of sensing it?

There are a few things that a shark may react to instinctively, electrical signals generated by a thrashing fish perhaps? Reaction to other stimulus is learned through association. How is a shark to learn what the presence of adrenaline means, if it is highly unlikely to be in a position to consume a land animal in the first place?

Does adrenaline indicate fear? Isn't adrenaline more indicative of excitement in general?

I think you're talking about a loading assist bar, commonly referred to as a knee loader which is a misnomer because you don't put it on the knee, rather on the foot the same as you would with the pneumatic speargun handle. It's one of a few adaptations that allow you to load a longer pneumatic. This device is not particular to any pneumatic speargun line, it's an aftermarket accessory.
