It is not uncommon for a geologist to construct his or her own Jacob Staff.
If you are considering such a project, give some thought to the ways in which
you can increase this tool's utility. The Jacob Staff outlined below pulls
triple duty...

Not only does this Jacob Staff serve its usual purpose, it is
also a walking stick.
The palm grip/wrist lanyard setup is available at most outdoor
stores and screws onto a ¼" coarse-thread stud seen
below. |

In addition to being a Jacob Staff and walking stick, this staff also serves as
a mono-pod for field
photography. The same stud that holds on the palm grip above also
receives any camera that can be mounted on a tripod. (See below.) |

Overall, the staff is 1½ meters tall. The
½-meter and 1-meter positions are marked with thin
bands of fluorescent orange tape making these key thicknesses easy to spot. |

To prevent wear and increase longevity, the base of the staff has a large steel bolt screwed into the end. A
lock-washer helps hold it in place.
Be sure to drill out a large pilot hole for the bolt and include the thickness
of the bolt and lock-washer in the staff's overall measurement. |
