Makes sense considering the boat is most likely moving. The rope would be in a large arc as it is dragged through the water. So it's useless to measure the rope.. Even if the boat is stopped currents at the bottom would drag out the arc. I've seen this ice fishing with a gabbu for lake trout on Keweenaw Bay in Mich UP and sometimes the bottom current would require a heavier barracuda just to get to the bottom. ;>)}

They have an interesting collection of tools for sale.
Actually -- not that expensive compared to some things.
But also -- does Rob's source actually *want* that tool, now that he knows what it is? Maybe he is willing to sell it to you for somewhat less than the new price. (But also, he may indeed want to keep it, but you can at least check.
I usually take my own photos or use ones that people send in, but in this case I liked the rivet spacer and just copied the photo from Amazon since I didn't know if I would ever see one in person.
