more prone to recording errors, so a good compromise is to keep legs down to
15m or less, which also makes sketching a little easier. Using a distoX above ground does make it hard to see the laser spot in bright

not be such a restriction on surface surveys, so don't do a rush job (it is
best not to do surface surveys when the weather is awful:-). A good
