Spear Guns for Home Defense?


Hello and welcome to The Slingshot
Channel. A lot of people want to know about home defense, and, in many countries, it is illegal to own firearms or keep them in the open near the bed stand. So, we are looking at an alternative. Spear guns actually are legal in many countries that otherwise are very, very restrictive. So, let’s try to find out if they are any
good for defending your home. We are looking at two compact models from the company Cressi. This is not a sponsored video,
though I bought them on Amazon at full price. They cost about 80 euros, plus minus. It’s affordable. I’m looking at the 50 centimeter type. You can get them in much longer sizes —probably be a lot more powerful too— but for home defense, you want something compact. You don’t really want something that is two meters long, so 50 centimeters is about the right size. So, two different models. Let me show you their features. First model that we looking at is the rubber powered model. As I said, it is 50 centimeters long, and this is the spear it shoots. As you see, it has this nasty little hook that I think is really needed if you want to hunt fish with it so that you can’t pull them out when you draw back the line but for home defense, it’s probably not really needed. Anyway, it is made from massive steel. That’s why it’s so heavy, and I think it is the heaviness that makes this so effective because it is **** near unstoppable. It has no fletching, which is really not needed for this purpose, since we’re talking about short distances. Defending your own home really means that five meters is about the distance you have to look at. No fletching is needed for a thing like this. To load it, you simply put it through the muzzle hole here, and then you put it into the corresponding hole in the lock, and you can hear it engaging. And now it sits nice and firmly inside of the weapon. What I really love about this is that you can load it so quickly because you can’t have this fully-loaded just without the rubber band cocked. And cocking is so easy because you simply press it against your chest, pull, hook into the notch here— Actually, there is two positions that you can use for that purpose. One is a little bit more to the front for a weaker shot— and then it’s ready for the shot. It does have a safety that you may or may not use. It doesn’t automatically engage. And it is really easy to shoot it then. Wow. We know shooting from five meters distance to see how straight it flies and we shooting into this thick archery mat. Again, cocking is super easy. Just like that. Let’s fire away. As you can see, it went in fairly deep. This is the distance. I’d say that’s probably a good 12 centimeters. Alright, ballistic jelly shot. Whoa! That was rather impressive, but it came in a little high, so I think we have to shoot into a lower position again, so we have comparable results. Now we’re talking! It really shot through this 20% ballistic gel block. Unbelievable. I think you can really clearly see that it is the momentum that does the penetration here. This is a very slow shot, but it has so much momentum that it’s just unstoppable by the gelatin. Now we’re looking at the next model. It’s also a Cressi, but this one works with compressed air and not with rubber. Of course, we always prefer rubber powered weapons, but let’s have a look at this. First of all, it is a little bit more bulky but, then again, you don’t have any tangling bands, so that’s an advantage. Otherwise, it is fairly similar. Short. Very maneuverable. The arrow, or the spear, is a little different. As you see, it also has these hooks, but there are two of them. The arrow looks like brass, but I think it’s just brass-plated steel. It’s really heavy. And, of course, it has to be airtight here. When you buy it, it comes fully pumped up, which speaks volumes about the quality. I mean, you know, you could probably store it for years without losing the pressure. But then, they also give you this pump with it, and this pump goes into the butt end of the thing. And then, you have to pump, and, you know— Of course, I tested this. and I believe this is one of
the hardest things I’ve ever done because it takes about two hundred strokes, and they’re getting successively harder. So, I really had to do this in shifts to get it back to full pressure. That is my main reason why I can already say that this is not the preferable home defense weapon. It just takes too long to
reload. Then again, if you only need one shot, you could keep it loaded for a long time. You really have to force that spear down the barrel. This takes some time. You don’t wanna do it when an intruder is already in the house. Okay, let’s see how much power it has. Wow! Wow. It went through the block like it wouldn’t even be there. That’s probably one of the most powerful compact shooters that I’ve ever seen. Pretty good wound canal too. See? It forced the whole thing, complete with spring and everything, through it. Now, this thing really is awesome, but no, I would have to take, like, two hours or something to pump it up again. So, how can we make a rubber-based model be more powerful because this has the right power, but it doesn’t have the right reloading time. What do we do here at The Slingshot Channel when we want to increase the power of a rubber-operated weapon? Well, we double up the rubber. Okay, if we look closely to how this is set up, you see that the attachments here have a little groove, which is perfect to tie some string around it. It’s too tight for rubber. And on the other side, we can easily simply use rubber bands to attach more rubber. In this case, Thera-band Gold. You can make several powerful slingshots with that much rubber, but in this case, we’re adding about 66 pounds of draw weight to the spear gun. And I’m a little afraid that if you use more, you can no longer cock against your chest. And also, maybe the mechanism will fail. Okay, and here is the souped-up version of the rubber-powered spear gun.As you see, this has been attached with a little bit of string. Yes, it’s thin but fits perfectly
into the groove, and it’s rated at 40 kilograms. This means far more than enough for the 33 pounds/15 kilograms that these bands have per side. And on the other side it is attached with rubbers bands—two— because these two make sure that this rubber cannot slip off. Okay, for comparison, we’re going to shoot it into archery mat first. Let me see if it’s still possible to cock this against your chest. It is harder, but it’s still very doable. Alright… and fire! Wow. This went in clearly deeper. Let me see. Oof. It’s also not easy to pull it out. It went in that far. And I would say that is a good four, maybe five, centimeters additional penetration into the archery mat. Okay. Ballistic jelly test. Wow. Clearly more penetration. The standard version only had the spear poking out to here and now we gained this much. Alright, now let’s see how it behaves over a longer distance. This is about a good, I’d say, ten meters now. Okay, as you saw, it flew alright for about 10 meters. That’s about where the ballistic gelatin block sits. But then, after the next five meters towards the mattress, it started to tumble, so this means up to 10 meters, it’s still kind of okay, but certainly had enough power to reach 50 meters. Of course, any cheap crossbow would cover a much longer distance, and the projectile would fly with a lot higher speed too. But then again, this is so heavy. This is so much more heavy because it’s massive. It’s solid. It’s not a hollow piece of aluminum. It’s solid piece of steel. It’s a veritable steel spear. Both of these weapons are really powerful enough, specifically with the strengthening. I prefer this one for home defense because it is so much easier to get ready. And also, you can practice, whereas with this thing, it is just too hard to load. The pumping is just too exhausting. They both have one significant disadvantage. That is, you have one shot only, which I think is really not good for home defense. You want at least two shots so that you could give a warning shot. And therefore, I think what is needed is a two-shot version of a speargun. Since there’s none on the market, I’ve decided to make one. I already drew up the plan for the system. As you see, two triggers. And it will be made from aluminum this time, not from wood—what I normally do— because this still needs to qualify as a spear gun, so it can only use waterproof materials. Stay tuned for next weekend because then I’m going to show it to you. So, I hope you like this becausethat’s it for today. Thanks and bye-bye. Oops. Flew a bit high.****

  1. If I was someone who hide behind a tree, under a table or behind a wall at Joerg's home during his demonstrations, I would be worried.

    Joerg will kill you without notice it

  2. I always wondered what would happen if you fired above water without detaching the leash. Could it bounce back and stick you?

  3. A warning shot? You have GOT to be joking, right? Why not just ask the bad man to be nice and go away? Lunacy pure lunacy. The best situation is for "it" to be over before the bad guy knows what happened.

  4. I don't think this penatration will kill or disable people. It'll most probably be just a stick stuck in the bad guys stomach and he can still harm you. Maybe a custom tip can help?

  5. If we here in Australia used that on an intrude in our home and killed that person we would be charged with murder. That is how well we are protected by our government!!!

  6. In Germany, the holy grail of firearm evolution it might be your only legal option in defending your residence from unfriendly Third World visitors.

  7. Me personally I prefer a handgun either that or a shotgun because criminals ain't going to break into your house with a speargun either so if you have a speargun and they have a gun you're f*** as far as that goes I also like having a gauntlet

  8. The stupid thing about those countries which have band certain fire arms from registered owners is that the criminals are better armed than you

  9. just saw the ad about the spray gun cleaner…. odorless?????? Man, That's the best part of a clean gun! That way I know she's cleaned & lubed up right!

  10. 2 1/2 minutes in you mention the second notch for a weaker shot. That's not what it's for. Take another look at the point of the gun. Below there's room in that notch for a second band. This is to use TWO rubber bands at the same time for a much STRONGER shot. 😉

  11. You CAN get a second band into the notch in front. It's just very difficult. Do it when you're in a warm room and the plastic end has been warm for several hours. This will prevent brittle plastic and cracking.

  12. You don't need to pump the pneumatic gun after each shot. It works like a shock absorber in your car it just stay at same pressure for years.

  13. If you live in a country where it is illegal to keep a firearm by the bedside you can always do the right thing and keep a firearm by the bedside, just use some common sense and lock your bedroom door if you have small children

  14. The hole at the gun attachment at the end of the tube is designed for a second piece of elastic tubing. You can use as thick and as short (more tension) as you can pull back. Then you hook one on spear slot one, and the other on slot two. All my spearguns are doubled up, giving them far more power.

  15. All my spearguns is made out of wood (the gun itself) but the spear and trigger is from stainless :p no issues with water.

    I know people who even have the spear out of wood and it works just fine for night fishing where you can get upclose without the fish moving

  16. That's why I'm proud to be a American… Shall not be infringed.. my life my choice… Wish the European countries would join us.. can't even protect yourself because criminals don't obey laws…

  17. Ancient post so probably no one will see but HOME DEFENSE? I'm all for it. In a crime ridden area, 3rd world I guess but can't you get AK47s in such? Here's the issue in Western World. Your attackers aren't making an appointment, if they are breaking in through windows and thats your warning sound 1 you'll need to hear it, and you won't if reasonably asleep have TV on are on another floor. So, your time to grab your weapon is going to be the seconds the attacker bursts into the room with you. You need your weapon at your side, oh and you need to be awake, be able to see… Insist you need it to patrol your premises when you 'hear a noise' ok, that'll work. So will window / door / area / pressure / laser alarms that are about 99% effective in getting rid of attacker while you hunker down in another room calling for cops with real guns and body armor and yes sure hiding behind your home defense weapon in case the attackers are overly goal oriented, until the swat team arrives.
    The term HOME DEFENSE needs to go into the dust bin. The only REAL reason for most to have just about any weapon isn't home defense, it's THUG DETERRENCE. Juvie gang wanna bes. Perverts. The lune next door that has 20 busted cars on his lawn four rapid dogs deal drugs does drugs is on trial fighting eviction…. and your best bet to keep him at bay until cops / courts / his landlord outs him is him KNOWING he'll die if he crosses the line. OR Just your abusive ex significant other who courts and cops don't care ignores the restraining order. Of course, it only works IF THEY KNOW YOU"RE ARMED, and given the law in western world just telling someone you'll kill em if they come after you can be a crime, so you might try keeping it out on display, cleaning it when they can see you remembering of course you gotta keep it safe which no doubt means a trigger lock

    Hey, Joerg how about a video on securing weapons safely?

  18. I have still got my spear gun from the 70's. It has two rubbers on it, one for each notch in the spear for higher power if required.

  19. Some comments on spearguns, rubber powered in particular. You may take it as read that this is from an expert spearfisherman. For their intended purpose, longer is always better. This is mainly because most shots are made from as close a range as possible, ideally less than 60cm from the tip to the target. This is the opposite of what's wanted for home defense. Coming around a corner to confront an intruder might be very difficult with such a long weapon. Second, the most common tips are total crap. Those conical ended things with the giant flaps are really good for tearing a ragged hole and allowing a fish to escape to an unnecessary and unbeneficial death. Much better are diamond tips with shorter, staggered flaps. But for those whose main interest in owning a speargun is to increase their catch, the pranger head is the ne plus ultra. If you are less interested in facing a murder charge than one of assault with a deadly weapon, you might also consider these for home defense. A person with a length of steel rod hanging out of them will still be pretty severely incapacitated. Third concerns power. Standard issue and most replacement rubbers, are, in my opinion, far too short. You really don't get much more power by stretching a rubber to within a millimetre of its life, compared to say, 85%. But you do get a much shorter life. Better to double up on the rubbers. As you pointed out, the spear has two notches, and most decent spearguns have provision for mounting a second rubber without modification. And if you find that the first one snaps while loading because its been quietly perishing, you still have a second chance. Fourth, I have encountered guns on which it was impossible to either engage or disengage the safety while loaded. You should ensure that this is not the case before purchase. Finally, and least important, is style. Wood is best.

    As an aside, some years ago I got a feral cat, shooting from the hip at a distance of about 7 metres (the closest I judged I could approach and with string removed). Hit the cunt fair in the scone. It was twilight, the spear flew in a nice arc, there was a brief pause during which I wondered if I'd scored, followed by furious reaction and a brutal clubbing. He became my doormat for a few years.

  20. This is sorely lacking in a safety warning. All spear guns come with a cord connecting the spear to the gun (usually 1-2 meter length) and a warning never to shoot it out of the water. because if you do shoot it in air without disconnecting the cord, you are most likely to hurt yourself rather than any intruder by the spear flying back in your face.

  21. Imagine you're a german burglar. You break into someones home and find a treasure trove of weapons and gadgets, but suddenly you hear something from the shadows
    Let me show you its features!
    HAHAHAHA
    that's the last thing you hear

  22. Do not use this device here in Texas because it is deadly . Unfortunately it will be deadly to you since return fire will be from a large automatic gun .

  23. Guestion… Speargun is for water, so have heavy spears…. What if you replaced the spear with a normal aluminum spear, with feathers on the tail end? (Normal arrow). Shoot it then, see what it does to accuracy and distance then…

  24. Joeje Thks for spending ur personal time 👍💪for great Videos U Do👍💪many people out there Envy U 😌cause they can not even Make a slingshot 😊

  25. You don't need a spear thrower. You, O Proud Briton, if one still remains in your country, you need to take back your weapons, which the vile socialists have taken from you.

  26. You do not need to pump the compressed air gun each time you shoot – I own several and I spear fish – they stay fully charged for many years without pumping. The reloading should be done with a hand grip that the spear end pushes into – just pull back anchoring the weapon on the ground or against your chest

  27. JOKES ASSIDE… SAFETY PRECAUSTION ! WHEN LOADING, MAKE SURE TO POINT TOWARDS THE GROWND !!!! AWAY FROM YOUR FEET !!! AWAY FROM PEOPLE/ANIMALS !!! and VALUABLE ITEMS !!! ONLY IF THE ABOVE PRECAUTIONS ARE MET YOU MAY LOAD… if you are in to spear-gun fishing you should know that! not to address the fact that the spear gun is made for underwatter use….

  28. Vietnamese New Year wish Joergsprave good health to invent many good products for my community and me, fans No. 1 THANH CONG 0948.336.418 OK

  29. Hi!
    1st- once you pump it it stays pumped unless is faulty it's "air spring" by pumping you increase the power.
    2nd- the loop at the front of your rubber speargun is an eye it's also for quick attaching extra rubber tubing. And then you using both slots on spear.
