2. The measuring line. This would be a thin plastic wire (of some flexible but non stretchable compound) marked out in centimetres like a measuring tape. No need for a string line and a measuring tape for sections - just hang your line level of the measuring line, and off you go!
Ha ha. I remember doing this in the early 1990s - not with plastic of course (it wasn't invented then!) - but by marking the string of my plumb bob in centimetres to speed up section drawing (on that particular site at that time I was doing three sections each about 60m long and 3m high). My further development of this was to tie the said dangly thing to a rod (grid peg was ideal) to which I had fastened a line level (using hi-tech string). This enabled me to take accurate points on a less-than-vertical section face with lots of rubbly bits sticking out.
Should have patented it really, but it's too late now!
