1. Learnt it properly from a technician. Video on you tube is certainly helpful but you really need someone to guide you through.Wow,3525 years, certainly older than mine and if that’s the case my reg still has a lot of life left. I believe I can buy the parts easily enough here but only see XTX versions, which I assume is compatible with the ATX? Did you learn how to service it from a dive shop or is it something I can possibly learn from YouTube videos? Also, I always assumed that the service tech used special equipment to test it before use, how do you do it yourself? Do you just attach it to a tank and check how it breathes?
I’m pretty sure my first stage is a DST since it had a swivel turret.
Thanks for the advice!
2. IP gauge is the only special gauge that I used for the 1st stage. You can spend a lot of money on equipment/tool if you want to fine tune the 2nd stage.
The IP gauge is a must and dirt cheap as well.
3. DST usually pairs with the 50 series. FSR with the 200 and DS4 with the 40.
