A tip. Keep arm extended when shooting speargun, especially with a midhandle. Hold handle. Rest butt on top of right forearm and stabilize with left hand if necessary. Bring sight picture in front while extended. Lock elbow. Deploy. Will get much more reach and power. The way you shot was equivalent to limp wristing a pistol. Just trying to help because you said you didn't have much experience. You lose a lot of power when you don't stabilize the gun. With 3 bands that Riffe would have likely fully penatrated the mat. Good vid. Really like the slow mo shots and have always wondered how a bow would shoot underwater.
@@jacquesdeklerk5563 I'm no expert but: "Cavitation is a phenomenon in which the static pressure of the liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid." . Isn't that basically what you are saying?
Had the bow set up at a pro shop. It performed just fine ru-vid.comUgkxQEKUoxLWwayEDZR0NKB-5limn4MBU-2L . And I would say this is a good starting now that I could pass down to my son when he is older.But the package was missing the release and a nock was missing from one arrow.Dealing with customer support was terrible. They suggested I buy a new release rather than correct their own quality control issue because it’s to expensive for the. to ship it out from China.Update: manufacturer got back to me and resolved the issue. I retract the above statement.
We ten years old used to do just the same back in the 60's in Italy. Under water fishing with home made bows and arrows and also slingshots with the same arrows, so much fun kids today could not possibly understand.
How I envy growing up like you. It seems to be soooo exhilarating. And you were probably the best age to do it at. When you're just dumb enough to not know everything that lives in the water, but just ballsy enough to take the disadvantage to have some fun and fetch some food. Kick ass brother. I'm proud to be on a planet that still has people like you around.
6:10 Look at how the water cavitates behind the string. I'm just returning to archery after a 35 year layoff. I dusted off my 1987 vintage Jennings bow, similar to a Bear I guess. The amount of engineering and sophistication in modern compound bows today is mind-blowing. Comparing them to a recurve is like comparing a prop aircraft to a high performance jet.
Matt Carriker cleans pools. Just give him a call. He drives an old El Chromino. Does all kinds of construction and cement finishing also. I'm sure he would do a cameo.
Bought my first riffe speargun in 1987 and it's still works great! I also got an old school bowtech Captain. Hunting and fishing is my life bro, cool vid 😎
Love the cavitation! You can also see there is some on the rubber bands of the speargun. If you plan to use it again, you might want to arm it resting the stock on your sternum (That's why the stock extends behind the pistol grip). Also, shoot it with your arm extended just like a one-handed grip on a pistol. You'll see it is completely neutrally buoyant for this exact purpose. I'd really like to see more speargun action in the future, like what model could go through a level 2 armor underwater? Some are ridiculously powerful, and some even use more rubber bands or a system of cams in the similar fashion of a compound bow
I invented this new way of jogging in the water. My wife told me some one else had already invented it and it’s called swimming. I’m always last to the party.
One reason a compound bow and arrow would be less effective is an arrow's guidance fins are positioned to spin the arrow to keep it on course, which while in water would present a huge amount of drag. Whereas a harpoon gun doesn't need this as the dense water prevents the type of drift that you'd get travelling through the air.
The cavitation on the compound starts only after the spiral profile of the cam starts curling the string. A visual proof of the mechanical advantage of compounds. Thanks for the physics practical class bro
Maybe the fletching the vanes increase the surface area with water resistance. Why not try shooting an arrow without the vanes to see what would happen.
Ok, seeing the cams rotate and the bow string creating that cavitation as it pushes the arrow forward like that was super cool. I'm gonna have to bring my bow out and shoot it some this weekend lol Thanks Richard! BAM ✋
Interesting to watch your experimentation on underwater shooting. Clearly a metal and heavier arrow is more effective underwater. Thanks for your demonstration.
i think removing the vanes on the arrow would be beneficial, especially if the vanes have any twist to them. the vanes are meant to stabilize the arrow through air which is less dense that water.
You could see a lot of drag on the string, which really shows the difference in why the spear gun works better. Now I'd like to see a crossbow. I realize there will still be drag, however there's much less bow length and much more pull. It will fall somewhere in between, and probably closer to the performance of the spear gun.
I've really been looking for an inverted crossbow shot underwater. Those have even less of a cross section compared to a conventional design. Sadly, there isn't anything like that on here so far, at least not with normal searches
The difference between dart (arrow) and bullets (bullets) is that the bullet comes out with a very strong thrust through gunpowder and also pivotally, and when the bullets are fired underwater, the bullet will cool down after a few seconds and stop its rotation and fall into the depths, while the arrow does not come out with a fire thrust but with a very strong thrust in a straight line. That is, it does not rotate and that helps the arrow to move forward from the thrust that it was launched from
A lot went into this and it was entertaining 👍 ! If you do this again two things you might try , use a fiberglass arrow we use in bow fishing , it’s much heavier and might give similar results to the spear fishing gun ! You could swap out the spear fishing arrow with a carbon arrow and see that result as well ! Just a thought !
This was bad ass! Seeing the cavitation behind the bow string and how it drove the arrow, with enough mucking around with that setup, you could make it work I think. That would be cool as hell, to take bow fishing to a WHOLE NOTHER LEVEL xD
I’m a dive instructor in Alaska . Try Johnson and Johnson baby shampoo mixed with water in a spray bottle ( 1 ounce shampoo , the rest water ) for your dive mask . It will absolutely never fog again . DONT RINSE IT OUT !!! It’s tearless and so it won’t burn your eyes . Nothing else works , not spit , not fancy bs , nothing . Baby shampoo for the win !!!
Most fun yet on tube. Doin stuff Ida never thought ah. Totally confused the 5.56 & 7.62x39 barrels remained intact, had "assumed" that introducing an (incompressible) substance into the barrel (should) cause a failure? D'oh!
Hey, FullMag, if you want your goggles to keep from fogging up just lightly spit into them before you enter the water. Smear it all over the lens and that should keep it clear while you're under the water.
Probably should have tried a bow fishing setup. The bow fishing harpoon arrows would shoot more efficiently than a hollow arrow and the vanes cause too much drag under water.
When it was still legal to bowfish catfish in texas I used my crossbow underwater. Since you dive, you maybe want to try wacking rays on the sand bars!
Crazy to think then when he fires the bow and you see that flush of emptiness as the string cuts through the water it's actually creating a small vacuume around the string as it displaces the water
Not much. The issue wasn't the fletching. I'm betting money on that he shoots really light arrows that probably even float. The energy the bow puts into the arrow going against the friction of the water can't sustain with it being light. Guarantee he put a heavy arrow on and the result would be drastic. Spear guns use solid fiberglass shafts that are heavy. No way in hell does almost any spear gun store more energy than even a mid line 60lb compound bow.
I think you should remove the fletchings from the arrow to make it faster in the water. I am not expert, but I thynk it is slowing down the arrow a lot
I doubt it. Needs to just be a heavy arrow to sustain the energy under that much friction. That's why the speargun beat the bow. All in the shaft weight.
wow how awesome - thanks for the effort - absolutley great footage . fishing arrow was already mentioned but I think it wouldn´t work at 80lbs never saw a fishing arrow with a proper spine for 80lbs.
Crossbow I feel is coming soon ND it's amazing how much the water slows the limbs down and because the power stroke is so short on bow compared to the spear gun it has a much longer power stroke to keep forward force anyways the compound if shot from above into the water like bowfishing it going fast to the bottom neat ass vid
I bet you could hold that sight picture for days. Need to revisit this one later in the summer. What would it take to make a bow shoot better underwater? Could you shoot the spear out of a bow....? The amount of drag on that fletching is really quite surprising in the slowmo.
I've always wanted to see someone underwater shoot a bow and arrow at a target outside of water. For example, being at the bottom of the pool and shooting up and out of the water to a target on the deck.
Winner Speargun! Solving a Problem that was solved 100’s of years ago. The Compound Bow String creates more resistance and slows the throw. The spear gun Floats, and is much more manageable underwater. I mean it’s all Ambush Up Close Hunting.
