DeWalt DWHT77100 100-Foot Handheld Laser Distance Measurer
The DeWalt DWHT77100 100-Foot Laser Distance Measurer is an industrial layout and estimation tool engineered for rapid linear, area, and volume calculations across commercial construction, electrical rough-ins, and finish carpentry projects. Delivering a maximum working range of 100 feet (30.5 meters) with a precision accuracy of ±1/8 inch at 32 feet, this compact red-beam laser device eliminates manual tape measuring errors during material takeoffs. Outfitted with an intuitive 2-button interface, a high-visibility white backlit LCD screen, automatic addition and subtraction logic, unit toggling between fractional feet, inches, and meters, TPE overmold impact housing, and two AAA battery power, this tool provides instant measurements for trade contractors.
Best Used For:
- Flooring & Drywall Square Footage Estimation: Calculating room surface areas automatically for flooring, drywall, and paint material purchasing.
- HVAC & Electrical Conduit Run Calculations: Measuring long linear wall runs and interior room volumes up to 100 feet to size ductwork and cable trays.
- Framing & Interior Layout Verification: Verifying stud wall spacing, doorway clearances, and ceiling heights without an assistant holding a tape measure.
Key Performance & Safety Features
- 100-Foot (30.5 m) Maximum Measuring Range: Projects a clear red laser line to capture extended interior distances quickly across large rooms.
- ±1/8-Inch Precision Accuracy at 32 Feet: High-precision laser sensor provides reliable measurement data for accurate material bidding.
- Integrated Area, Volume & Linear Addition Logic: Built-in digital calculator adds or subtracts sequential runs and computes square footage and cubic volume.
- High-Contrast White Backlit LCD Display: Bright illuminated screen ensures clear text readability in unlit attics, basements, and bright jobsites.
- Instant Imperial & Metric Unit Conversion: Toggles seamlessly between decimal feet, fractional inches, and metric meters with a single button press.
- Protective TPE Overmold Rubber Housing: Durable thermoplastic elastomer housing absorbs shock loads and provides a secure, non-slip hand grip.
