Bill Watts (Coconut Creek, FL) wrote to us to say
that he believed his Sherwood Avid BCD has a safety
issue that the manufacturer is ignoring. The plastic
holding the retaining straps for his tank broke, and
since the camband apparently does not actually run
through the fabric of the BCD, the tank was released.
When the plastic breaks, there is nothing to hold the
camband to the BCD.
When the same thing happened to his wife's new
Sherwood Luna BCD, on jumping off a dive boat in Fiji,
he was concerned this was a design fault and wrote to
Sherwood about it. The company replaced both BCDs
without question.
Recently he was diving with friends who had bought
similar Sherwood BCDs on his recommendation. Both
broke in the same way, the man's when he stood up
ready-equipped to dive and hers when she hit the water,
almost pulling her regulator from her mouth.
"I was horrified to look over and at 70 feet [deep]
see my buddy's tank floating away from her BC. I used
a safety strap I have for my camera to tie it to the BC
to get her to the surface. It could have been a very bad
situation if she had not been cool and calm and had
not been with such an experienced diver as myself."
There is no shortage of reports of this problem on
the Internet. This was pulled from a Leisure Pro online
product review, from an unnamed diver: "I am a
pro diver. This [BCD] was sent to me as replacement of Luna BCD from Sherwood. When I received it, I
was impressed with the new design. This was my third
BCD from Sherwood. It looked good, but it is a horrible
BCD. The backplate is of very fragile plastic, and it
looks exactly same as the Luna BCD that broke after six
months of use. I was very surprised that they continue
using the same style, since many of my friends had the
same problems with the backplate and stopped using
their product."
Charlie Bush, president of Cramer Decker
(Sherwood Scuba), told Undercurrent he was unaware that there was a safety issue with current models of the
Avid and Luna. On checking with his technicians, he
had been told that, bearing in mind there are twin tank
cambands, for the tank to completely separate from the
BC would require the simultaneous failure of four separate
components, which is very unlikely. He said the few
that have been returned with this fault have been several
years old and that Sherwood had not heard of any
failure happening while a diver was under water.
Well, we have told Sherwood of these cases and now
they are aware. Clearly, if a BCD camband breaks away
from its mounting point and allows a tank to become
unstable, even wrenching a regulator from a diver's
mouth as reported in one case, that could cause panic,
despite the tank still hanging there. It's a serious defect.
Let's see what they do about it.
