Man, I love this topic!
I was taught not to wear gloves since OW and I can understand why. Though these days, I dive with gloves all the time, I do think new divers should dive without it. Granted we have stings once a while, but I do think such stings do help develop skills and respect for all things underwater. Because I dived without glove protection for some time, I'm sensitive to what I touch. Even with gloves these days, the consciousness is already there. I've seen divers touching everything and anything underwater wearing gloves.. Some not even aware of it, and that is sad.
Having said the above, I do not agree with blanket ban on gloves. Like some have already brought up, diver's fins IMHO, does more damage! But I do not see any dc banning fins! They should educate and evulate their diver's buoyancy skills before making such decision. Of coz, this is easier said than done.
As for pointers, I use to love them, carry one make u look and feel like PRO!
it does have practical uses too! Eg, digging into sand when current is strong, pivot oneself when taking photos etc. but I've seen many divers using pointers as underwater walking sticks, indiscriminate tank banging (so damn irratiting!!)!
I stop carrying pointer underwater coz i cannot find a proper way to store them, and because I move very close to seabed, I dun like to see my pointer dragging on things. I think my buoyancy skills are generally OK, so I'm pretty comfortable without one. And if I really need to pivot myself for photo taking purpose, I have my gloved finger!!
