I still am by all accounts a brand new diver. I just did my 10th and 11th dives on Sunday. But I got certified in 2009 while I spent a year in South Korea. Having spent the majority of my life in the water pretty much everything came easy to me. I struggled with removing a weight belt at first, most likely due to the fact that I was severally over weighted. I believe I had on 30lbs for a 3mil wet suit. I remember that on the first open water dive, we dove in a small bay about 100yard from where some fishermen had nets in the water. They were apparently concerned that we were trying to steal their fish, because they called the Korean Police, who yelled at us for quite a while after we exited the water. The remaining dives after that went pretty well, I remember not being comfortable with navigation(still am not) but I managed to come back up in the exact right place. I think this may have been due to luck more than skill. I barely used any air compared to the other students, and on all the dives was withing 250psi of both the instructor and the DM.
Fast forward 2 years to this summer- I have arrived in Panama City, FL, Decided that I wanted to start diving again, so I bought a set of gear, and proceeded to do a dive at local marina, with no refresher course, which probably was a mistake. I had some gear issues which I was able on a later dive. However that initial dive after 2 years made me do some real thinking. While my Buoyancy skills are better than the average new diver (I was told Sunday by the DM on the boat that she would have had no clue that I was making my 10th dive after watching me) I think that I am still over-confident. My 3rd and 4th(8th and 9th overall) dives this summer I followed my buddy down to 75ft and never gave it a second thought. I went out on the boat and dove to the sand at 75 ft for my and felt comfortable. However doing some reflection, I followed my buddy to those depths on all 4 dives. I tend to follow more than lead. I'm not afraid to lead, but I always want to yield to the more experienced person. I don't think I would dive past where I feel comfortable, but I do wonder if my comfort level might just be greater than my skill level.
