Hi,
Ive gotten about 5 dives in with my D3/Zennith reg, Ive noticed that there is a low pitched " flapping" sound when im exhaling. This is my first reg, so i dont know if its normal.. but ive never heard this sound on any of my previous rental regs.
Would appreciate any explanation/assistance. Many Thanks!
