- **Takeoffs Anywhere**: No need for cables or a PC. Use it on jobsites, in your office, or even on your truck's hood to get takeoffs for estimates and place material orders when required.
- **Area and Volume Calculation**: Roll the length and width to calculate area, set the height for volume. Use imperial or metric units. Roll and store values with dedicated keys, and get clear answers on the display. Most users experience a +/- 2%–3% rolling error based on start/stop point accuracy and scale magnitude.
- **Manual Item Counting**: While rolling through plans, manually count items like studs, piers, outlets. Touch the Count button to add and the Subtract button to remove the last entry.



Using the Scale Master Pro is a breeze. First, if you're working with standard scales, just pick one of the 72 built - in scales or set up one of the 6 custom scales according to your plan. To do takeoffs, simply take the device to your work area, be it a jobsite, office, or your truck. You don't need any cables or a PC.
When it comes to calculating area and volume, roll the device along the length and width of the area on the plan to get the area. Then set the height to calculate the volume. Remember, the display will show your results clearly.
If you need to count items like studs or outlets, while rolling the plan, use the Count button to add each item. If you make a mistake, use the Subtract button to remove the last entry.
As for maintenance, keep it in a dry place. Wipe it with a soft, dry cloth regularly to keep it clean. Also, don't expose it to extreme temperatures as this might affect its performance. And based on the usage, you might experience a +/- 2%–3% rolling error, so double - check important calculations if needed.
