Well I witnessed a diver who had been certified nearly 20 years earlier. They were planning on going somewhere to dive and wanted to get a refresher course before they did. Probably a good thing they did because despite the fact that she had dove avidly years earlier she apparently over the 20 year period of non diving lost her ability to do simple skills like mask flooding. She tried and tried and tried but it just would not work.
What you have to remember is over time lots of things change that seem minor as we witness it.
One really way to notice this is to watch movies like Jaws and the scene where divers were going in and you will notice a variety of modern no nos. Regs with no octos, Horse Collar style floatation devices and the list goes on. Just imagine what all has changed since you got certified
We really did have octos, BCs and even computers 12 years ago. I haven't noticed that many big changes to equipment or OW training in the past 16 years. Certainly not the same as if somebody came to you having trained in the 70s, which was when my ex-husband had his training.

If you get a chance, try Pemba Island. The diving is amazing and there is a good operator of a live aboard there. The operator also have some lovely cabins on the mainland for day divers.Sierra Leone, huh? Never considered that as a diving area
I lived in Tanzania from 1978-80 and went to school with the kids of the man who later became the president of Sierra Leone (Kabbah).
I try to return to Tanzania every year for a few months where my landrover and I seek out and prey on tourists and take them into Selous game reserve and other parks.
Hopefully next time I go back I will get the chance to dive in Zanzibar. Almost did my o/w in Mombasa.
Wow, I just realized this thread was pretty old!
