that second rubber is supposed to be loaded also together with the roller rubber. in Europe we call it a booster and its being used on rollers because they have a slow start speed of the shaft so you need a regular band to get maximum speed of the shaft right away when it exits the muzzle.
your slightly wrong about the reason for less recoil , 24 years as a gunsmith, the main reason on that particular gun is the fact that you have rubber flying backwards underneath same time as you have rubber and spear going forward on top so they cancel each other out , like the reverse cross bow designs of recent years, mass helps but not as much as countering the rearward recoil with a forward recoil , some fixed firing pin machine guns have the same system of cancelling one recoil out with another or the use of directed gas or springs etc.
i never said it was cancelling the felt or actual recoil i said it was diminished due to the opposite action of the band, don,t forget the band is moving rearward before the spear has overcome inertia to move forward , so the initial, although be it small, movement of the entire gun would be forward or at least stationary until the inertia has been overcome , but we are talking milliseconds so its just semantics at this point , still nice to have an intelligent polite conversation on you tube for a change thanks .
Thinking about transitioning to a roller speargun. Watched your video to learn more and noticed the shirt. I approve (it’s me on the shirt)! Never did pick one up... gotta find me one!
You guys are awesome! You should make a video of your store, like where it is, what type of merchandise you have, see the staff all the cool stuff you guys have.
Hi Andrew! Very nice videos you have on Nautilus Spearfishing!! I saw that you pay very much attention in showing people how to do things right! And you are very good at it!! Having this in mind I would like to inform you on the recoil of a roller gun since you "seem" not very sure about it! As far as the recoil of a roller gun is concerned, is true much smaller than ordinary guns. In fact is 25%less. This is because at the "loaded" state, half of the band is on the top side of the gun and the other half is on the bottom side. At the "after shot" state, the full length of the band is on the bottom side. By doing some simple maths, it turns out the above result. So, as you mentioned in the video, less recoil means better accuracy. A good roller gun is capable of very tight accuracy at long range. But roller guns have a drawback too, as always is the case! They usually shoot downwards in more than 3 times the length of the shaft. The rollers themselves can produce unstable shot, along with overstreched bands and make it completely useless. But if you maintain good quality bands suitable for roller guns and hard straight shaft, you will forget everything else when power is a concern! Guaranteed!! Keep on the good work and keep diving! Regards, Ilias Pardalis
One more great explanation. Thank you. So when hunting only with the main roller band the extra band stays lose on the gun? It would block sight? It can stuck on shark tail of the spear during a shot, I think it is dangerous to hunt with a lose band moving on the top of the gun.
I'm totally new to this. Can someone give me some advice.. When you shoot a fish, is the there line attached to the spear which is attached to your gun ?, I've seen some videos where people shoot the fish then the line is attached to a buoy... I want to buy a speargun which has the line attached to the gun. What type are they called ?, or are the buoy attachment ones just normal ones with that feature added ?
Very good explanation, now I understand how they work. I have a question, but for a 100cm regular 2 banded speargun, this is the first time I ever own a band gun, would you mind giving me tips on how to practice loading the gun? I have a 100cm beuchat marlin Oceania
In theory would a rollergun be more powerful if you looped the rubber back on itself twice instead of once so that there would be three layers instead of two? Thanks
I am using regular and traditional spearguns with three bands of 5/8" but it seems to me the same strength when I shoot the fish, now I understand how the roller able to release more power than the traditional one. Could you please give me the link where to buy the roller gun parts? I can build the body all I need is just the parts to assemble home made roller speargun.
No guns yet, should have some on soon. This gun is for sale but only through cal or email right now. Let me know if you are interested andrew@nautilusspear.com
The opposing forces of the bands going down the gun over the top and through the rollers and finally getting pulled under the gun towards the handle will cancel each other out.
I had one in the 70's. I found it a disappointment. Perhaps that is a good one. I found the rubber would bind on the roller. It was such a pain to load and untangle I actually threw it away. It was a big waste of rubber. Long bands folded over a roller like that would not behave it would tend to bind I stick with what is well proven and simple. I suppose the the new models work better but the gun I use is simple and works well. Power is not a problem.
Must be nice to get a big fish, but you need powerful equipment, I don't have even the weak ones, I am grateful for you to send me your equipment is old instead of throw it, send it to me for the benefit of

Does it still work at max velocity if the secondary bands a smaller band, say if I am running 16mms in the rollers and like 10mms on the secondary

it's actually the mass of the rubber going in the opposite direction that cancels out the recoil of the spear
Simon Long exactly what I was thinking
Great Vid Andrew!
Well explained, thank you, Mate!
informative--nice presentation

wow amazing gun bro.
Nice video. Could you help me about Fusion 1 versus clasic roller same Leght. What is the pros and cons?

never seen em
is the shaft carbon fiber?
Awesome video! What’s the wood gun on the wall on the background?
Andre Euro ;)
In theory would a rollergun be more powerful if you looped the rubber back on itself twice instead of once so that there would be three layers instead of two? Thanks
The more pre tension at the muzzle the more power so in theory yes as long as the rubber maintains stretch
Tks Bro... I Use Roller Speargun Too, Wooden Made
I am using regular and traditional spearguns with three bands of 5/8" but it seems to me the same strength when I shoot the fish, now I understand how the roller able to release more power than the traditional one. Could you please give me the link where to buy the roller gun parts? I can build the body all I need is just the parts to assemble home made roller speargun.
amazon that shit man.... there's a lot of roller gun mods online. and "how to" videos so you can do it yourself
FaddaWolf Thank you brother I appreciate it.
Do you guys carry that particular roller gun in stock? What sizes and price? Tried looking it up in your website but to no avail.
No guns yet, should have some on soon. This gun is for sale but only through cal or email right now. Let me know if you are interested andrew@nautilusspear.com
Mantap bro!
ilove speargun for my life wow
I had same gun , but it is not roller head , can you tell me please how to make roller, i dont now can i punch barell , tnx , best regards
Hello can you please send me a web site to buy this gun cant seem to find it online thanks
Email me if you can andrew@nautilusspear.com this is an old video and the gun has changed a bit since then
How much??
How much
The opposing forces of the bands going down the gun over the top and through the rollers and finally getting pulled under the gun towards the handle will cancel each other out.
Send to me the page store i live in Puerto Rico
Show how to make roller with a rail gun
How much it coz sir for one unit speargun roler 110cm... Pm mi d prize.. Tnks ..
My biggest fear is the ocean so I have no clue why I'm watching this, somehow came here from Jaws
Im sure you can build it too guys. Just look for wood prix page

Aim rite Roller
Hello brother.....
waht are the handguns back there?
Those are just speargun handles for barrels
bullshit
Rodrigo Gonzalez lmao there handles
***** Fuk you and your fuckin handles shit
He told you the truth moron. those are handles for spearguns. you can customize your speargun with different handle types.
really really.
Can i have a spear gun to be delivered right into Fiji Island
Sure!
Hm
I'm sure you can find awesome woodworking plans on woodprix website
money $$$
Me ayuda con su número amigo para contactarme soy Andrés de Ecuador un gusto saludarle
why do you care about the recoil? the recoil would matter if you would be able to have a second shot.
