I had to check the date on this post to make sure it wasn't still April Fool's Day!
So you lost one of your weight pouches and DIDN'T NOTICE it was missing until the next day? Either you only carry 1-2lbs in each pouch, or your weighting is so far off that it's ridiculous.
PS - maybe you should invest in day-glow yellow weight pouches so you will notice when you drop them by mistake.
Again I point out this is the "Basic Scuba Forum" not the I'm already a divemaster forum. If you talk to your students this way you won't have too many repeat customers.
