We love our sharpies too. But we use a great pencil called the 'noblot ink
pencil - 705' from Sanford. They cost about $0.33.
When they are dry, they write like a pencil, but when they are wet, they
make a nice blue dot or line. Works great in getting down through the gel
to the skin. However, they aren't perminant, so we follow up with the
sharpies after the leg dries.
One thing you need to keep in mind when you are doing vein mapping with any
ink...you should only mark going one direction, if you head back up into
ink filled gell territory you can make a mess.
One drawback: We train a lot of people and have a few probes with black and
blue smudges on them ;)
