Default Weights -

Hi All!

I'm not sure if this is in the right place... but here's my issue...

I have learnt to dive in Mexican water's... the sea... all the sea... even my confined waters were in the sea...

Now, in Mexico, i was around 125kg (275lbs) in weight... And i had 10kg (22lbs) of weight around my weight belt whilst diving... In salt, sea water.

I have now returned to the UK, and am continuing my diving, for now, in swimming pools...

I am now, 121kg (266lbs), and will obviously be diving in a swimming pool...

Can anyone help me out on what estimated weight would be needed in this situation... also, can anyone advise me on how to work this out?

Thanks heaps!

You only used 22lbs in sea water when you weigh 275?? I weigh 220 and use 28 lbs in so-california waters. In the pool I use 24lbs.

What suit were you wearing? That will have a big effect. My numbers are for a 7mm suit. In Mexico, you may have worn no suit at all or maybe a 3mm??

I would start with your exisiting weight and then add or delete weight in 1 or 2 pound incriments until you achieve neutral. Hopefully you can do this in a pool with some help.
Dive Safe.

What tanks were you using? Al have positive bouyancy as they empty. Steel is negative. You shouldn't need much wgt to get down, just wgt to stay down at the end of the dive. I use steel myself and dive with 6lbs in fresh water with a 7mil and I'm a big boy too!
Not being able to get down is one problem.(skill/experience) Not being able to stay down at the end is a different one.(not enough weight) You want as little wgt as possible to help with bouyoncy and it also reduces air consumption.
Do like he says add or subtract in small increments. When you are trying to descend remember to STOP moving and exhale COMPLETELY! Just before you descend lean back and let ALL the air out of your BC.
At the end of a dive if you find yourself floating to the surface when doing a saftey stop add some wgt. Most tanks are no more then 5lbs + bouyant. So keep your wgt increase in that range. Salt water? add about 8% over fresh.
Have fun and dive safe!
