Are all DT20 models the same?
The green laser is much brighter and more visible than a red laser, especially in outdoor and bright lighting conditions, making it easier to see the laser point at longer distances.
Does every DT20 include laser measurement?
No. Laser measurement is only available on selected DT20 models. The THD in-store version includes laser measurement but does not include Bluetooth.
Does every DT20 support Bluetooth?
No. Bluetooth connectivity depends on the specific model purchased. Models without Bluetooth, including the THD in-store version, cannot sync measurements to a phone or tablet. If your device supports Bluetooth, you are able to connect it with your Smart Life App on your phone.
After DT20 is switched on, a flashing connection icon (↑↓) indicates it is waiting to pair with the app. When the icon remains steady, the connection is successful. Meantime, enable Bluetooth on your phone, and open the app. Tap the "+" on the upper right corner and click "Add Device", it will automatically search for the device to connect.

How do I use the digital tape measurement?
Turn on the device and pull out the tape. The measured value appears on the digital display in real time.
How to activate laser measure mode?
Short-press the Measure button to activate the laser. It automatically turns off after 30 seconds; press the button again to reactivate it.
What does the Zero function do?
Short-press the Zero button to set the current position as a new zero point. Measurements taken from there begin at zero, making it useful for relative measurements and marking distances.
