Hello everyone I am new to these forums. I am looking at getting a new full faced dive mask next year. Currently i use a ots spectrum but it can be very uncomfortable after extended use and I would like to get better periferial vision. What masks have you tried and why do you like them? Are there ones that have integrated stage 2's that can't be modded to use with surface air i.e hookah setups and if so which ones? I have been looking at both the ots guardian as well as the ocean reef neptune space g. Does anyone know if the can be converted to low pressure surface air?
