Finding user manuals and guides for older surveying equipment can be a royal pain. Over time members have thankfully submitted their old operators documents and workflows. Lately, i have seen a rise in questions related to older Sokkia equipment so I figured I'd post a few hard-to-find manuals for your use. Hopefully one of these might come in handy for you.
