Picked up our regs for a trip in two weeks last night. We did a Scuba Review/Refresher Pool Class immediately after pickup. My reg seemed fine, maybe a little too free flowing, (I need to educate myself on ip). However, on the way home hubby said his reg had an intermittent stutter. The dive shop was closed at this point. Should I call them and have them take another look or is this normal? LDS is about 45mins-1hr each way away or would have run it back today. They gave us a printout of all the values and said everything looked normal and clean. Its an older Aqualung Legend Regulator, but he never noticed this problem before. It had been almost two years since diving and service at the same LDS. Thank you for your input.
