Key Features of Mountlaser Claw type Holder for High-Precision Applications
Universal Pole Compatibility & Secure Clamping
The series is designed to fit a wide range of surveying poles, with clamps accommodating diameters from 20mm up to 40mm. Whether using standard 32mm (1 1/4 inch) GPS poles or varied-sized surveying rods, the selection of Open Clamp and Quick Release designs ensures a firm, slip-resistant grip in the field.
Integrated Precision Tools for Accurate Alignment
To enhance surveying efficiency and accuracy, many models (such as the TC-3 and TC-4 series) come equipped with built-in Compass and Bubble levels. these integrated tools allow operators to maintain perfect verticality and orientation without needing additional external accessories.
Modular & High-Efficiency Mounting Systems
The product line features advanced mounting options, including Quick Release (Q/R) mechanisms for rapid equipment transitions and 1" Ram Ball integrated designs. These ball-and-socket systems provide flexible, multi-angle positioning, making them ideal for high-efficiency workflows and complex site setups.
Versatile Support for Diverse Hardware
Beyond fixed cradles, the series offers adjustable holders with variable widths (ranging from 72mm to 110mm) and heavy-duty brackets capable of supporting 8/10" tablets. Whether using a compact smartphone, a specialized GIS handheld, or a large-scale tablet, the series provides a stable mounting solution for a wide range of field controllers.
Principle of the Claw Type Hoider
Ten Uchwyt typu pazur operates on a three-point mechanical clamping principle, ensuring self-centering and rigid stability for prisms or laser targets. By utilizing spring-tensioned or screw-driven “claws,” the holder provides uniform radial pressure, aligning the optical center precisely with the mounting axis to eliminate eccentric errors in high-precision surveying.
Common Questions & Professional Answers
Heavy data collectors (like the TSC7 or Mesa 3) often slip or rotate on the pole when using basic clamps. The "Claw" design provides a mechanical positive lock that wraps around the device, preventing downward slippage even in high-vibration environments.
Unlike traditional clamps that rely on sheer pressure (which can damage carbon fiber poles), Mountlaser's Claw holders distribute the gripping force evenly, ensuring your $5,000+ data collector stays secure without crushing the pole.
Mountlaser Solution Highlights:
- 1Rigid Cradle Design: Models like TC-8-22 (TSC7) feature reinforced corners to prevent frame flexing.
- 2Anti-Slip Gaskets: Internal rubber lining absorbs shock and increases friction on the pole.
Pro Tip: For ultra-heavy tablets, the TC-8-23 (Heavy Duty) is specifically engineered to handle the center-of-gravity shift common with 7-inch and 10-inch devices.
Surveyors often struggle with "universal" holders that end up covering buttons or ports. Mountlaser offers device-specific geometry for a perfect fit.
| Pole Diameter | Recommended Clamp | Device Match (Examples) |
|---|---|---|
| 32mm (1 1/4") | TC-3 / TC-4 / TC-5 | Standard GPS & Prism Poles |
| 20mm - 40mm | TC-1 / TC-1-1 | Adjustable range for thin or oversized poles |
| Tablet Specific | TC-8-23 / T57 | Mesa 2/3, FC5000, RT3/RT4 Tablets |
Always check your device width. For example, TC-6 supports widths between 72-92mm, making it ideal for the Getac or Archer handhelds.
Based on Reddit feedback, surveyors moving between many stations per day save up to 15-20 minutes with a Q/R setup.
Mountlaser TC-4Q and TC-5Q allow you to detach the collector in one second without unscrewing anything—perfect for taking the unit into the truck or checking a manual site point.
Benefits of Quick Release:
- 1Instant Portability: Quickly move the collector to a vehicle mount or a second pole.
- 2Less Wear & Tear: Reduces repetitive stress on the clamp threads, extending the holder's life.
Mountlaser Advantage: Our Q/R systems use an integrated 1" Ram Ball option (TC-8-3Q), giving you full 360° rotation to eliminate screen glare in direct sunlight.
A common Reddit complaint is "cheap" levels that go out of adjustment. Mountlaser integrates adjustable vials on models like TC-3 and TC-4-2.
Pro Calibration Tip: Regularly check your holder's bubble against your pole's main vial. If they don't match, use the adjustment screws on the holder to center the bubble. This is critical for vertical accuracy when using data collectors with tilt sensors.
Durability Features:
- 1Anodized Aluminum: Resists corrosion in rainy or coastal environments.
- 2Recessed Vials: Level bubbles are set into the frame to protect them from impact if the pole falls.
