Why? You think a tech class is even remotely comparable to 4 year university degree?
Some people keep saying x or y class was hard and when you asked why, it's always that they had issues with some basic stuff. I started cave with 800 or 900 dives or so when I was in my mid 20s. Thought the skills were all pretty basic stuff.
I know the next question:
Before someone now wants to know If I have ever 'been in the water with gue diver' (I know, I know because they (think) they're so much higher level). Yes, I have, more than once. I was just diving with a hardcore DIR fan C2/T2 not too long ago. Still don't see what's supposed to be so hard to learn. There are other sports that are much harder to get good at, I think.
How much time did those 800 or 900 dives take to master your skill before you became a cave diver? Say 4 years? Lol
