I’m smiling as I read this thread. From a beginner’s perspective I think it almost impossible to understand the skill/comfort which can be achieved underwater. My humble introduction to scuba was through back-packer diver in SE Asia. We rented well used equipment and spent all our time enjoying unique marine life found in the coral triangle. Every dive was a trust me dive. I was absolutely thrilled to blow bubbles and enjoy the fish! Most of us couldn't be bothered with details like navigation and dive profile planning. It was clearly the job of the DM/guides to keep us alive and find the boat again.
Then a women at a homestay on a small island of Malaysia Borneo shared Scubaboards address. I was completely shocked at how much you all had to say about scuba ;-). My initial assessment was that you guys were seriously uptight about diving & and most likely had very bad local diving with long stretches of boredom (which justified all the time spent arguing on SB ;-).
I had logged about 60 dives or so, and thought myself a decent diver, but had never heard of trim, had no idea various kicking techniques existed, rented poor fitting equipment, leaking masks, and every dive was a trust me dive. YES - we were having loads of fun just blowing bubbles and looking at fish without any neurotic advice from Scubaboard!!
Fast forward a few years, a few more classes past AOW (listed in my SB profile - if you are curious). I don’t think GUE training is for everyone, but it was certainly a very fast and efficient path to accelerate my dive skills and help me become an independent cold water diver. The trust-me critter dives were great fun, but having the skill to safely slip into most conditions alone with a trusted partner is much more exciting and confidence inspiring! Knowing the capability of my equipment, being able to position my body exactly where I desire, having the skill to hover effortlessly in one spot to look at something or take pictures (even just inches off the bottom), having the confidence to navigate back to the boat/shore, knowing how to plan my own profile, understanding true risks and how to manage them, and having extra awareness to help out friends or the guide if needed – has made diving much more safe and FUN ! I certainly don’t think DIR equipment/training is the only path to achieve this comfort, but it is undeniably a very efficient way to gain much more skill quickly.
The other day I met a young college science student just starting a career in underwater research. He had only logged 12 dives prior to taking Fundies. All of these were training dives to prep for the class – which amazingly he passed in doubles. He asked me to help him with some skill practice, which I did. During the dive I paused the skills to enjoy an adorable turtle. After the skills we kicked through some beautiful swim throughs. I found it quite shocking and sad to hear that this was the first “fun dive” he had ever enjoyed.
Despite popular misconception, practice to improve skills doesn’t necessarily always require hard serious sessions or a one track focus on skills such as this. Much of my skill was fine- tuned looking at critters on fun dives. Sure, we do occasional skill dives, but they are always filled with laughter. It's more common that we just do a skill or two in the shallows at the end of a fun dive. There is always plenty of fun, critter watching and even the occasional bubble ring
Yes, I totally relate to just hoping off a boat and letting the guide worry about the rest

. But with experience, I have found diving is both much more safe and fun if you continue to improve your awareness, personal/partner skills and dive trustworthy equipment that both functions and fits ;-).
I've seen divers complete Fundies with 40 dives and skills that it took me 300 dives to achieve (I took Fundies with 270 dives). We all have our own pace & training path.
Just keep learning & having fun ;-).
