Mini-Guide to fewer digs
We know that the further away a fragment is from the location where you do the survey,
the direction accuracy is also diminished.
- Green: 5-40y and almost directly where the Theodolite is pointing.
- Yellow: 40-80y possibly at a narrow angle to the left or right of the theodolite.
- Red: More than 80y and potentially at a very wide angle to the left or right of the theodolite.
We're going to assume you mount/fly for red distance and walk/run for green and yellow (unless you're a druid with instant flightform)
Apply the following two simple tricks.
- Double-survey Red.
That's right, if you get a red theodolite do another survey on the spot. This will allow you to limit the angle variance significantly.
- ↑ ↑ Your 2 theodolites align perfectly there's a good chance the fragment is where they're both pointing.
- \ / or / \ Your 2 theodolites are pointing at an angle to each other, there's a good chance the fragment is towards the split of their angle.
- Depending on how the 2 red theodolites align with each other, vary the distance of your 'jump' to next dig point.
- ↑ ↑ Your 2 theodolites aligned perfectly; move +Red distance from your current location: 90-100y away.
- \ / Your 2 theodolites are pointing at an angle to each other; move Red+Yellow to Red+Red distance (further) from your current location: 140-150y away.
Take into account the borders of the digsite and survey nodes Archy has recorded before to help you.
These two things will help you significantly limit the number of Red digs you need to do before you're into the yellow and green zone where things become trivial.
