Leica GS20 Tripod

The MP401E is Keson's only electronic wheel with a steel frame. It is the world's sturdiest electronic measuring wheel and the easiest and most comfortable to use. It will stand up to the harshest conditions.

Swan-Neck Ergonomic Handle
Patent-pending "thumb-up" grip ensures less wrist strain and superior control.

Reliable Input System: Magnetic Sensors
Dust, dirt and other particles can disrupt a light beam used in competitive units. Magnetic pick-up avoids these problems.

Sealed Counter Encasement
Designed to NEMA Class II standards, our counter housing ensures that it will not be damaged by rain. What's more, you can saftely clean the entire wheel with a damp cloth.

Counter Size and Placement
Our easy-to-read digital counter is in the most protected spot on the wheel. With the handle up, it is nearly impossible for the counter to come into contact with the ground. With the handle down, the roll bar offers solid protection. Counter requires 2 AA batteries (not included).

Keson RRT12 (M)

Leica Carriers

The two new long distance wheels, known as RRT6 and RRT12, also come with a hand brake that is set on the pistol grip handle, enabling users to stop counting instantly, exactly where they want, and thus preventing users from adding length accidentally. Each wheel also features a fail-safe collapsing hinge that snaps into an extended lock with a simple flick of the wrist, while disconnecting rather than breaking if the user forgets to unlock the trigger. The wheels are designed with convenient storage in mind, as each one can be collapsed in the middle to enhance storage and portability. Great for use in construction, road marking and paving, fencing, surveying, traffic control and insurance, each wheel also features five-digit magnified counters that track feet and inches up to 9,999 feet and each wheel comes with a two-year warranty.


• Enhanced grip pistol-type handle increases control and comfort
• Re-set on the handle AND on the unit housing
• Re-set on housing is reinforced to protect it when re-setting the counter with foot.
• Brake on pistol grip — stops counting instantly.
• Collapsing hinge — snaps into extended lock with the flick of the wrist
• Center-line handle design with counter on top of wheel
• Compact fold-down — easily reduces to 1/2 its size for storage and portability.
• Flip-down kickstand (Model RRT12)
• Gear & shaft transmission for highest measurement accuracy and strength.
• Handle lock

  • Double screws to hold the housing together in the event of a drop.
  • Better blade axle to reduce breakage due to the weight of the tape if dropped.
  • Lifetime warranty on these products.


  • Tough, double nylon-coated steel blades.
  • Break-resistant under severe use in the field.
  • 3/8-inch wide blade reduces wind drift and tape weight.
  • Metal-reinforced crank handle for durability.
