Dive knives when out with a DM

[Belzelbub]

The Russians have an underwater rifle that fires special ammunition more akin to darts. Much more range:

APS underwater rifle - Wikipedia

There also used to be a speargun made on a similar principle, though it actually used a spear as opposed to a dart. Johnson SMG (SubMarine Gun) was from the '60s. Occasionally, one may pop up for sale, but it's been a while since I've last seen one for sale.

It essentially used a spear pressed into a bullet casing.

Here's one that showed up on Pawn Stars several years ago.

But, the use of firearms for lionfish is primarily a gimmick. There really is no need as they feel they are invincible, so it's not problem to get real close.

As a reformed spearo myself, the lust for a Johnson SMG never fades. I've seen and held the single barrel version, but never the quad barrel, nor the double barrel. That gun is to die for.

Much easier to get a quick follow-up shot. No bolt to retrieve and reload. I would say you could get many more Lionfish in the same window of opportunity.

I guess if you are hunting lionfish with a speargun that would be true. But, on most lionfish hunts a speargun is not the weapon of choice.

Personally, I use a less than full size pole spear (3 piece pole spear with only 2 pieces assembled). Nothing to retrieve. Lionfish goes from the end of the spear to the lionfish tube without having to touch the fish. And unlike other fish that will scatter when one gets taken, lionfish don’t seem to care.

Plus, I never have to touch the fish until out of the water. A dead lionfish can still sting.

Diving at home I always carry a small folding knife in my pocket, a linecutter mounted on my other pocket and shears on my belt. I guess getting entangled under water is my worst nightmare. When traveling I take my folding knife.
Divers with a huge knife mounted on their leg are compensating for something.

Or maybe don’t want to spend too much. I have a 4.5in blade that I strap to my calf. I wanted a smaller knife BUT this is titanium and I got it for about $40, something ridiculous (it’s now more than double that price I think). The smaller knives that can mount on my SPHydros Pro cost about $100.

I just bought the mounting kit for my BC and will see if I can Jerry rig it for my knife. If not I might just put it in my SP dive shorts pocket with a lanyard, not fancy but could do the trick.

Just a heads up on these Linsen knifes. The guy is selling them again on Fleabay. He's asking five bucks plus 12 for shipping. He made me an offer of 4 dollars. It's a good deal on a BFK.

BTW: Those that claim divers who carry a huge knife are compensating for something, are compensating for their own feelings of inadequacy. It's called "Spring Boarding" or Narcissism. It's mean. After all, nobody is saying anything negative about your little one!

I am. I laugh when I see those cute little things

Anyone who is old enough to remember Sea Hunt will know, Russian spies can show up at any time and will go straight for your reg hose. Be safe out there.

Well yeah sure we all do but that's not the same as saying something about it. Good grief! Be kind. Besides, they're all small compared to mine!!!! BWAHAHAHA.
These are my regular BFK's.

This is my "goin' to the church meetin' RBFK. (That's for Really Big Friggin' Knife)

For comparisons:

That's twelve solid inches of saw toothed razor edged Titanium! Yeehaw!

Ok, it's not really my dive knife although per the manufacturer, it would be ok for it. (Strapped to my tanks for an over the shoulder draw maybe?) It's really the bush machete for my off road race car.

Hey Mods. If the photo's are to big, let me know and I'll fix them.

I have had to cut fishing line enough times to carry 2 cutting tools , guided dive or not, I was caught up in fishing line early this year on wreck where fishing is not allowed , https://parks.des.qld.gov.au/__data/assets/pdf_file/0022/164524/ex-hmas-brisbane-bw.pdf
Heavy line and large hook , a local told me it is fished at night.
This and a trilobite, the Mares version on my waist belt.
