Rob Allen has been working with latex tubing for spearguns for years. Testing and retesting until he found the right manufacturer and mix to ensure his guns have the best, most consistent bands, to maintain accuracy over 100s of shots. Rob’s focus was on offering a latex band that could maintain its tension for as long as possible. The aim for Rob was to have a rubber that could be cut to peak performance, (say 60kg tension) when loaded, but only lose a couple KG of tension after an extended period (say 40min). This is important in maintaining accuracy and speed. It’s what makes the difference between Rob Allen rubbers and cheaper brands. Many other bands will load up to a peak tension of say 60kg but within 5-10min, this will drop back down to 44-46kg, so they are losing significant power over a short period of time, thus affecting spear trajectory, accuracy and speed. The key is consistent quality of the raw material latex and the manufacturing technique and environment. Rob Allen rubber is a laminated pure latex core with a UV resistant outer layer.
