What is the angular accuracy of the Eclipse Pro compass? Is there a compass that has angular accuracy to within a second and can be camera tripod mounted? I am trying to build a fence through dense brush and trees.

Measure the same offset at both ends of your fence that would give you a clear sight, establish points visually along the clear sight path & measure back over to your true line. Can't do that? Bearings on deeds are not necessarily oriented to magnetic north given on a typical compass...could be 10-15 degrees off depending where you live. Many legal issues could arise from your fence building, check your zoning regs and hire a surveyor.

a second?! No compass in the world can, nor ever will, do that! Such precision is only possible by repetition of angles with a high-precision theodolite or total station ($10,000+). Did you mean 'minute'? Best you will do with a compass is 15 minutes and that could change later in the day to a different reading. Some places pull the compass off several degrees. Overhead wires, sun spots and other features can affect compass readings as well. A compass is for approximating directions. Beware too, that computer programs will often give one second accuracies where no such accuracy could ever exist.
