My wife and I are having a ball at this. Ive been at it since the late 60's and she just started a year ago. She gets all wound up at the thought of getting wet. Got her certed OW and NITROX and started learning all over again in a place called blue lagoon. 25' deep quarry with a silty mucky bottom and fairly clear water with 25+ vis. Each time I set her up for a mild failure and she remembers it and we move on. we do share airs each time we go out. She can follow a compass quite well. We are working on shooting buoys, laying line. charting the bottom wrecks and sites. she is having a ball learning. Buddy skills are coming around as is her ability of awareness of surroundings and my presence or lack of. She is a speed demon at times. She is still new but I would take her to 60+ with out worry. We are going on a cruise this may for her first gulf diving. No matter what we make the learning fun. We re both 60ish. Next year it will be AOW for her. I am fortunate.
