Dear Coral Listers:
About pens to write on transparencies underwater, I received quite a few
suggestions. They are summarized below, thanking efforts of all the
responders.
Most mentioned greasy pens which come in different colors. They are easy
and not expensive.
To get much higer resolution, one can use transparencies for color
printers. These transparencies have roughened surface, thus a pencil can
leave fine lines on them. They might be more expensive than regular ones,
but is very effective if you want to trace the position and shape of small
objects underwater.
Sincerely
Keryea Soong
