Hovering and weight issues

I am in the middle of my DM course and can do all the skills but am struggling with the hover. I can do it flat, but as soon as I try to do it in an upright position, my tank takes me over backways. I can't move weight around as I am negatively buoyant in a full 3mm wetsuit without any weight. In fact I need a new BCD as I can't float at present on the surface with my current BCD full of air without finning! not quite sure what my body is made of - lead maybe!

Anyone have any suggestions?

I know I can pass my course by using the flat position, but I would like to be able to do it upright too!

I tend to either cross my legs, hold the fin tips, else curl up into a "cannonball", arms tucked under my bent knees.

If you're practicing this shallow you may get into the problem with differential pressure, the air expanding more if your head/shoulders are above the point where you were neutral when horizontal.

Am practising in the pool at about 12ft. The Instructor just makes it look easy, but as soon as my feet lift - I tip over backways.

I have done it horizontal in open water as in a free ascent safety stop, but really want to be able to do it upright, in particular as I want to contiue to instructor and it would be easier for assisting and demo if I can do this.

Wow! Really?

Regarding your question - if you can get a hold of Alu tanks instead of Steel tanks, this might help a lot with both being too heavy and balance. Otherwise, what Mark said.

Some body/gear configurations just will not balance. What are you using for a cylinder? Swapping that may be a balance point unless you consider it to be cheating.

As soon as your feet lift.....maybe some light ankle weights to trim you out?

As it was relayed to me, I really didn't know there was any other way to do it for many years.

It was also used and demonstrated in my DM and IDC/IE classes, which given the candidates were from a variety of stores in and around our province, it seems to me it has become the defacto standard at large.

Glad I could be of service to you my friend


:no

For the OP, I too had the same problem with my verticle hover. My solution was to stop doing it that way.

Mind you if you're truly negatively buoyant with a full BC, I think you sholdn't be wasting any time on getting vertically trimmed with that set-up, as it's wrong from the get-go and the exercise is pointless.
