Default Off the wall question: Underwater plumb bob?

I kinda like the trailer knobs and adjustable fishing bobbers. I have
accumulated several GPS units so getting back to the same general place
will not be a problem but these test have gotten a bit more complicated
than I first thought. last time we just duplicated the Practical Sailor
tests and got pretty much the same results. This time I want to measure
creep under loads 10-15% below where they drag, how far they sail from
the drop point and get more accurate mesurements on how far they take to
set. A lot of that requires mesurements in inches.

All this may seem a bit over the top but if I am selling these things I
want to know everything about them. Besides, I made a little profit on
the anchors last year and need to be able to show the tax man that 10
days in the BVI is a legitimate business expense. ;-)

Anyone ever seen such a device or have a better idea?



IMHO, you can't get there from here with what you are considering.

Your friend will be a high speed, hand held GPS.

You won't get it for $100, but it will do the job.
