Hi, I’m getting my first regulator set and I am leaning towards either Apeks XL4 + or Aqualung Helix compact pro. I will be diving UK waters so need a suitable cold water reg but will also travel to dive in the med at least once a year. I also have a bit of jaw issue so was recommended to get a lighter 2nd stage. Can you advise which would be better, Apeks seems to have good cold water reviews but I like the idea of the auto closure on the aqualung. Does anyone have any advice on these or a suitable alternative?
