I have been partial pressure blending (tri mix) for a number of years now but have decided to build a blending stick
Before doing so I have a few questions.
I am using the oxidation hacker to start with and have read a lot of forums. A few years back I saw a big debate about what material to use. Stainless was considered the best but if using plastic which is best. ABS or PVC?
Second question is if anyone has had success doing a single stick for trimix to keep the size down. I will be using this on my charter boat so being able to have a smaller unit would be good. I have seen a comercial unit that does this. Two barbs in one stick, add O2 to bring it up to 36% and then add helium to bring it to desired mix (ie 21/35)
