The main consideration in using neon was predominately for remote diving with the two advantages it offers over helium of greater passive thermal protection and speech intelligibility.Thank you for valuable information again.
Neon doesn't seem to be bad, definitely compared to Helium - at BOC a J of N4.4 will set you back 250 pounds or so, it's a steal compared to He.
Do you know if there's any data available for decompression with Neon vs He in Trimix?
Data is still available but it's all pre computer and would take an age to get it all together. It also goes back a heck of a way and involves a lot of input. Neon 75 in a He trimix with N2 was the all rounder the nitrogen helped increase the gas viscosity although from a gas density position its is worse than the others but the viscosity reduced the WOB with the N2 causing minimal cognitive degrading and it also helped that pretty much helium tables could be adopted. Thinking about it with six degrees of separation I think everyone back then was in some way involved and played a part. Things have changed.
