- Just wanted to add my 2 cents worth.
-
- I completely agree with Bruce about the problem of weights in
- cold water diving. In a full 1/4" wetsuit w. hood, diving in the
- N. California area, I use 30 lb of weight. I also have problems
- with 2 discs in my back. When I dove with a weight belt, although
- neutrally bouyant in the water, all of the 30 lb was pulling down
- the center of my back when I was horizontal, and stretching my
- spine when I was floating vertically on the surface (BC pulls
- upper body upward, weight belt pulls lower body downward.)
-
- The solution: A Zeagle BC! Actually I didn't buy it for
- that reason, but since I have been using it, it has significantly
- improved the wear & tear on my spine while I am in the water. Why?
- Because the weights are in the BC, and as a unit the BC becomes
- neutrally bouyant. This is most apparent on the surface, when it
- feels just like I am floating with no BC or weights. Underwater
- when I am horizontal, there is still a slight effect of the weights
- on my mid-spine, but the BC tends to spread out the effect of it
- moreso than a weightbelt.
-
- There unfortunately is a downside. The total weight of the BC,
- tank and 30 lb of lead makes the unit quite heavy to manhandle.
- You have to be very careful not to mistreat your back while carrying
- or lifting it. But that is what buddies are for - right?
-
- Cheers,
- Phil
