Product Information and Details

Clearly one of the best Surveying Prism Poles we've seen on the market in a long time. The Crain Prism Pole comes with handy features, as well as being tough and accurate!

Grip-Tite Locking System on Prism Poles
The Grip-Tite locking system eliminates elevation errors from lock slipping. High-strength elastomeric pads grip the telescopic sections. The lock is self-centering and can be adjusted with the allen wrench (included).

Topo-Boot and Steel Point
Another innovative, yet exclusive feature of Crain's Prism Poles is the Topo-Boot. The Topo-Boot screws over the precision point and increases the area of the point for use on soft surfaces in topo shots. The Topo-Boot is removable and stores conveniently under the level vial when not in use. The Topo-Boot is constructed on high-impact Lexan and is included as standard equipment.

A replaceable precision tip/point is standard on Crain Prism Poles. In the event that the precision point wears or is damaged, it can be replaced in the field. The tip is constructed of a special hardened stainless steel.

Stedi-Rest
This multi-functional product is exclusive and comes as standard equipment on Crain Prism Poles. The innovative Stedi-Rest can actually take the place of three separate products. One of the most popular uses for the Stedi-Rest is as an equipment protector that can keep your equipment out of mud or water. The Stedi-Rest can also be used to check the calibration of and re-calibrate your pole's level vial. Another use is to attach the Stedi-Rest to a tripod for a pole support system.

Snap-Apart Sections
In the event that dust or sand gets in the lock, causing it to malfunction, simply unlock the lock, extend the inside section(s), and pull up on the section.

Adjustable Prism Mount Adapter
An adjustable prism mount with lock nuts is standard on all Crain Prism Poles. Additionally, specific offset adapters are available for a variety of prisms. Crain Prism Poles are calibrated with both metric and feet scales.

Lightweight, High-Strength Materials
Crain's Prism Poles are the lightest Surveying Prism Poles available on the market. Not only are they lightweight, the Prism Poles are constructed of extremely high-strength, durable materials. Crain's Prism Poles are available in Alumilite (aluminum), Carbonlite/AL (composite carbon with aluminum interior sections), and Carbonlite (composite carbon) models.

Large Level Vial
A large 42 ARC level vial is standard on all Crain Prism Poles. This large level vial makes plumbing a breeze. The level vial is adjustable with an allen wrench (included). High-precision 10 ARC minute level vials are available.
