This video compiled years of research and experimentation to show you a fast and reliable step-by-step way to calculate and setup a double banded speargun (in this case a Pathos Sniper 95) that can be applied to most conventional guns.
Bands Used: Sigalsub 14.5mm extreme (1mm ID)
Shaft used: 6.75mm Sigalsub HRC Double Barb
Dyneema: Pathos 1.75mm
Always do your due diligence and experiment to find what works best for you!
Thanks for watching!!

Hello, Bro. Nice video. But there's some miscalculations in my opinion. The real working length your gun could offer (from the center of the band in muzzle to the back end of the sharkfin) is 105 cm. Then it looks like you have something about 7 cm wishbones with fastening loops. Divide it by two - 3,5 cm, and 1 cm of rubber on the end of the band to secure the loop. So, you have 4,5 cm of "dead length" from your 105 cm "working length", which does not give any rubber strecth and power. So, 105 - 4,5 = 100,5 cm of actual stretch of 65/5=32,5 cm band. So, the actual real stretch ratio is 100,5/32,5=3,09 or 309% 💁‍♂️

Good idea to explain all in writing :)

Is the wishbone not calculated in the length of the bands? The longer or shorter the wishbone will change the stretch correct?

I ask myself the same and no one seems to lose a word about it 🙄🙄

@MikeTheGuy33 2 месяца назад

It has 307% elongation, not 330%.

Are there any differences in the formula when we are calculating it for inverted roller? Awesome video

@arnodesmedt3029 4 месяца назад

Is it me, or did you forget to count the wishbone length?

@MikeTheGuy33 2 месяца назад

Yes, it's should be 105 - 4,5 (wishbone one side), so he has a bit longer for 3,3

@zaydsteel804 3 года назад

How about different size rubber?, like a 12mm or 14mm or 18mm etc, any formula?

@mustspear7009 3 года назад

Usually there are tables for famous brands, that state what is best for each diameter and this is where I find the percentages used in the video. However, as a rule of thumb, 300% is optimal. Too much and your bands wear out quickly, too little and you sacrifice their full potential for longevity...Hope this helps!!! Have a good one!

Hi, I am planning to make a 120 cm wooden spear gun. The shaft is a 7mm/160cm. Which bands would be better to use 16mm or 14mm?

@VidarrKerr 2 года назад

16mm.

@DeepBlueSpirit2 Год назад

A 7mm shaft with 160 cm length is best propelled with 14 mm small inner diameter bands, stretched at 360%. For 7.5 mm shaft use 14.5 mm small inner diameter stretched at 380%. Both options get you lots of power but also a 'smooth' acceleration that equals to nice range and good accuracy. The 7.5 shaft oscillates less than a thinner one, has also more punch when hitting fish (penetration). But a 7mm is fine, tho.
