I love these reviews you have helped me so much in the past. I think a more more representative Measurement of energy is going to be the area of a triangle. For a roller it's the triangle plus the rectangle. Coatesman's does great job explaining this in his(understanding rollerguns part 1
Good video but unfortunately mathematically not amazingly sound. All you need to measure are two numbers: the speed of the spear the moment it leaves the gun (you need special equipment) and its weight and maybe its length-diameter for some additional distance adjustment.
Our method is perfectly mathematically sound, it just doesn't yield a number that can be expressed as kinetic energy or momentum. Our calculation does however yield a consistent number that reflects changes made to bands, shafts, and gun length, and serves as a comparison point between guns measured with the same formula. We would love to one day be able to measure true kinetic energy, but unfortunately, the logistics of measuring shaft speed underwater are out of reach.@@YuraAst
What a great video! Thank you for taking the time to test everything. Will be visiting your shop as soon as my eardrum heals! 💙
Glad you found it useful! I have a bunch more ready to go as well 👍
Should try different band sizes abd different manufactors, keep it up

That’s why we do it! We’ve been chatting with Coates to figure out how to express the roller power effectively with our system so stay tuned!
