I DID IT!! I'M CERTIFIED! had no problems with clearing my mask thanks to all the great advice from fellow board members!
in fact, mask clearing was the least of my problems. on the first day, seas were about 4-6 feet with 6-8 foot swells. we were getting our butts kicked going up and down the anchor line around the 15 foot mark. very strong surface current. another boat in our area lost 2 divers in the current (didn't drown, just carried away) and found them 4 hours later.
second day - weather was worse - so it was off to Vortex Springs. COLD!!! finished up the rest of our required dives/skills and had 1 tank leftover. so my husband and i did our first unsupervised dive. it was great! cold - but great!
