I am looking to purchase the Galileo HUD computer but do not want to switch masks. I have a TUSA style prescription mask, from Seavision, that I am very happy with and have not been able to find a compatible Scubapro mask that fits my face properly. Does anyone have experience modifying the Scubapro mount for the HUD or am I going to be forced to purchase a new prescription mask that is not comfortable to make it work?
