I have a question about the rubber bands on my Apnea competition 75cm speargun. It came with a single 16mm or 16.5mm band. I’ve been using this for a while now but I recently upgraded to two 14mm bands. I was wondering if this will make my shot more powerful, less powerful, or no difference. I’ve tested it out but it’s a bit hard for me to compare. While I was using the original 16/16.5mm rubber band, I would load it to the second notch. For my two 14mm bands I could only load one to the first notch and the other to the second notch. I would love to receive some advice regarding the difference in power/performance.
