    I'm just wondering if there are common things that beginners have trouble with. I did my first OW dive today, and although it went well (in that it was cool :p ) I know I was having trouble with a few things, like equalizing. My buoyancy was OK under water, but I strangely had trouble in shallow water staying upright, and my weight belt kept shifting. I'm curious if these are common beginner things, or if there's something I can be doing differently.

    weight belts are a pain for new divers.
    remember to tighten them underwater as they go slack due to the pressure.
    if you keep diving you will probably ditch the weightbelt and go for a better solution.
    equalizing is just practice.
    staying upright is not a good thing.

    just keep diving and things will get better.

    Buoyancy is the hardest thing for new divers to master, and true mastery of buoyancy can take hundreds of dives. Coupled with buoyancy is trim--the ability to maintain buoyancy while in a good horizontal posture. During a dive you should look like a fish, with your body parallel to the surface and without needing to move your fins to stay in position. Fins are for propulsion, not for keeping you at your current depth. If you stop kicking and immediately start to sink, then your buoyancy is off.

    Let's look at a couple of points in your post.

    The shallower you are, the more difficult it is to maintain buoyancy. You were taught how pressure because of depth affects gas compression, and you should have seen that the biggest changes occur in the shallowest water. That means that going up or down a fwe feet will impact your buoyancy much more than the same depth changes will when you are deeper.

    As far as "staying upright" is concerned, do you mean with your head above your feet? If so, why do you want to do that? As said above, you should look like a fish, with your body horizontal.

    A shifting weight best can be caused by the compression of a wet suit. When you descend, you will need to tighten your weight belt because your wet suit compresses under pressure and makes you thinner.

    Thanks for the replies! I think tomorrow's dive is going to be all about buoyancy and weight belts :p

    By staying upright, I mean when standing before we start the dive. We were doing a shore dive, but it was about 4 feet deep where we had to get in. So we had to stand on the bottom. But for some reason, I kept falling over, whether because of the weights or the BCD or the fins or all of the above haha.

    It's not easy to keep your balance on your feet in dive gear, particularly if you are in moving water. It helps to keep your side toward the water, rather than your front or back; you present less of a surface for the water to push on that way. I have also found that practicing my balance on land has helped a lot -- just standing on one foot and then the other while brushing my teeth has made a difference.

    Use your buddy for balance while you put your fins on, and don't put your fins on where you are going to have to walk much -- walking in fins, whether in or out of the water, is hard to do.

    As already said, weight belts need to be tight, especially if you are wearing thick exposure protection. You don't state your gender or your location, but if you are a man diving in cold water, it can be difficult to get a weight belt to stay put, because the combination of conformation and thick neoprene means there isn't a real good place to park the belt. A lot of men diving in cold water turn to other solutions, like weight harnesses, or integrated weights in the BC.

    I think, in my experience, the biggest problem new divers have with equalization is that they're so overloaded with all the things they have to remember, that they leave it too late, when it's difficult. It's a very good practice to "pressurize" your ears before you even start down -- and then plan on equalizing every couple of feet. Of course, if you are overweighted, your descent speed may be so fast that it's hard to get your ears cleared in time. If you let the air out of your BC and plummet, you should check your weighting.

    That's a very common problem. I especially have that problem because of my serious lack of flexibility, and I sometimes have a hard time getting my fins on. I once fell while wearing double steel 108 tanks, and getting back up was interesting.:D

    Here's what you do. Get with your buddy. If you are putting on your fins while wearing your gear, put one hand on the buddy and put the leg on that same side in a figure 4 position across the other leg while you pull on the fin. You will be using your buddy as a crutch to replace the leg you are lifting. It is especially helpful if your buddy holds your second fin while you put on the first one.

    If you are just trying to cover ground, again use your buddy. Lock elbows to hold each other up.

    When putting on the weight belt bend over and with your back parallel to the ground tighten the belt. With practice you should be able to dive without retightening the belt. When you tighten the belt standing upright, gravity moves the belt onto your hips and you cannot tighten it all the way, and when you become horosontal in the water (even on the surface), the belt slips off your hips and is loose.

    Using a rubber belt can solve the problem. I also tend to keep my weights on my hips and foward, with no weight on the back of the belt (when tank diving) it is less likely to shift if it loosens.

    boulderjohn has the answer for donning fins in the water. With time you may be able to do it on your own using your balance and BC instead of a buddy.

    You want to be horizontal underwater. If you're having trouble staying vertical at the surface, you might have a back inflate BC, and in which case, put less air in the BC.

    My advise for the weightbelt : Wet it before you put it on. Put it on SNUG...once you get to 15 ft, it's going to loosen a bit due to neoprene compression. I just adjust for that at the surface.

    Also, get heavy weights if you need'em! I think it's ridiculous to see average-size wetsuit divers with half-a-dozen weights on their weightbelt.

    Welcome to the hobby. :)

    Well I think the others have covered all the bases. Congrats on your first dive and have fun tomorrow, and don't worry about any small issues it does get easier with time.

    Our instructor let us integrate our weights into our BCDs once we were done with all of the required skills that involved removing the weight belt. That was after OW dive 1 or 2; I forget which. You might ask if you can do that, so you have one less gear issue to worry about.

    As for equalizing, if you're having trouble, don't be afraid to ascend a few feet until you get it fixed. If your ears are too far out of whack (especially if they already hurt), it's almost impossible to equalize them without ascending a few feet first. No need to add air to your BCD to do that; just kick up until the pressure in your ears goes away.

    Myself and many other divers tend to have trouble equalizing at around 10-15 feet deep. Take your time in that range, and you'll find that it's much easier to equalize when you're deeper. Often I have to spend a good minute around 15 feet down, just equalizing. I have to keep equalizing as I descend after that, but I don't have to stop or ascend again after that.

    I see the 3 biggest beginner challenges as learning to control breathing,balance and situation-awareness.

    Breathing: Establishing a good breathing pattern before initial descent, focusing on slowing it down further, knowing that neutral buoyancy using the BCD is done after establishing good breathing.

    Balance: learning to control the hips to go from an upright position (initial descent, venting BCD on ascent) to a horizontally trimmed position without kicking. Having the abdominal muscles slightly contracted to keep the legs from sinking.

    Situation awareness: is knowing where you are, how much air you have, approximately how long that will last you at a given depth, no-deco time- basically respecting the rules of diving without having to narrow your focus on any one of them.

    Back to the original post, I would say new divers have a tendency to not monitor their gauges, and sometimes to chase after some cool thing or creature they see. Skills like buoyancy control and body control come with practice and repetition. They often focus on those things and forget to to others. Stay close to your buddy and be aware of where they are. Monitor your gauges. Don't chase anything- you'll never catch it anyway.

    Dive went great. I paid a LOT of attention to equalizing, and turns out that pinch-blow gently-swallow works for me. I had no ear trouble at all. I also put the weights in the BCD -- SO MUCH EASIER! still having trouble with buoyancy and balance, but in all this was probably the least trouble I've ever had in scuba gear. Now it's just practice.
