I need help in building a counterweight

[apneus]

Hello

I would like to build a simple system of counterbalast which is based on two buoys, blocks, and shekels. Can you send me your drawings, links or photos of your design ?


Any help would be appreciated.

Make sure to search through the forum archive - I remember a few threads with photos, and perhaps even some building plans. For example this one may be interesting, but there are many more. Use different variants of the term when searching (counterweight, counter-weight, counter weight, counterballast, counter-ballasst, counter ballast):

Also the article at Freedive Central may be of interest. It comes from CIPA, the club with probably the longest experience in this field:

I made one works very well off my small zodiac.http://forums.deeperblue.com/safety/81499-diver-retrieval-system.html I ended up fixing it up one of the tubes having the dive end up front and heavy end just clearing the rear. With the right weight we were coming up at 1ms+.We are now going to put it on a catermaran for a local lake. will post pics soon.
