The advantages of the of the
“Freedivers” Counter Weight system are:
The counterweight itself of 30kg is actually 2 weights of 15kg each. One of the weights is permanently suspended from the bar by a stainless steel ring that allows the weight to travel independantly down the line.It is released in an emergency by a snap shackle.
As there are equal weights of 15kg at the end of the dive line and on the other side at the end of the counter weight line, adjustment for depth is easy .
