    Thanks Julio.

    Think about what? Ciguatera? Think seriously. I was like you until....

    Yo me ciguate una vez, with this fish. It's a lizzard fish.



    I remember well because it was the biggest one of its kind I've seen so I shot it. I hit it with a glancing blow on the side of it's face and crushed half its head. They're always on the bottom and the fish shot up in spirals with an open mouth almost all the way to the surface.


    I ate a little of it baked and two - three hours later was f*cked up. I'll never touch one of them little buggers again. The big one had quite a bit of meat on him. Se vengo asere!

  • Rob Allen new shafts. Very poor quality

    I found out you can bend a shaft by swinging it and cutting the swing short abruptly. The weight of the shaft and the momentum will make it want to continue in an arc and it will bend. I found this out after I was curious how one big fish just shook and the shaft bent without any pressure on it from another object or the line. So I duplicated the effect at home. This was with a Riffe stainless steel shaft. I'll try it tomorrow with an RA shaft.


    This is the test I want to do <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x"> http://spearfishing.world/3196-post20.html

    Quote from Tin Man

    If you want to measure the stress at which a metal will yield, you have to pull it harder and harder and note the point at which it gives.

    This is what I had in mind from the beginning. Hang a weight off the center, take it off and see if the shaft is straight. Increase the weight and repeat until the shaft acquires a bend.

    Since we see enough of these jellyfish I wanted to find out the name to distinguish it from the more dangerous Portuguese man of war. They are called common or Moon Jellyfish, scientific name Aurelia aurita. The ones we saw were about 1' to 1.5' in diameter. There was a lot of them but I've seen them denser on other occasions. Are they called moon because of their shape or because they tend to congregate on full moons which was yesterday?

    Common Jellyfish (also called Moon Jellyfish), Aurelia aurita, which do not sting humans. The threadlike tentacles around the edge of the bell can sting, and may occasionally catch small swimming animals for food, but their stings - like minute harpoons fired by springs - are not powerful enough to pierce our thick skin.

    Another source.

    The moon jellyfish is very common in the oceans of the Earth. The sting of this jellyfish can cause irritation in human beings, but it is not nearly as serious as some other jellyfish stings. It catches food by stinging it with nematocysts on its tentacles, then uses its four mouth arms to grab the food and digest it.

    Are these the ones that took a liking to you Jim? I did see yesterday the effects of the sting on Alan's face from the previous dive. I'm wondering how painful it is as I've never been stung by them. May be a good occasion to wear a hood.

  • Broward/Monroe FWC report excerpts

    The one with the dog caught my eye. Some of the other ones read like a how to manual, or rather what not to do to get caught <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x"> I'm sure that in the cases where these people get caught it's %99 of the time that someone snitched. Reminds me of Cuba.

  • Mask reviews and defogging procedures

    Quote from Marco

    I have a Samurai and it fits well but I prefer a Sporasub Sniper. That's the one I use most. I don't like small masks.


    I can sacrify a little bit of internal volume to get more pheripherial vision. Anyway, I inhale the air remaining in the mask while ascending.

    Is this the Sporasub Sniper mask you use?



    I wonder if it compares to the omer Bandit the same way the Sporasub Samurai compares to the omer Abyss.


    The omer Bandit mask.


    I find the omer Abyss and Bandit to be identical in fit and lens size. The only difference it the Bandit has less plastic in the frame. I thought of getting the Bandit for sake of having a lighter mask but after handling it I saw that it is less rigid due to the thinner frame and figured that it would break easier. I couldn't feel a difference wearing it. The Bandit is also more expensive than the Abyss.


    What is the distance between the corners of the lenses on the Sporasub sniper?



    If the Sporasub Sniper is no longer available what is the Mares equivalent?
