Pardon me, but I'm a little flabbergasted.
I haven't been diving that long, I only got certified in 1998, but we did learn tables and they hammered them into our heads. Granted it was a local course intended for local diving so they prepped us to be 100% self sufficient divers that could plan and execute a dive on our own with another OW diver without any guidance. Of course tables have been replaced by computers now, but the rest is still the same.
I'm just curious, is this part of OW training now at these locales to not need any personal data where you guys claim this is commonplace? Are they teaching "Just follow the guide"?
Or are these people just blowing off their training and not buying computers because they don't want to waste money on something they don't use anyway?
