Features
- It can be used for a long time (250 hours).
- It can be used for one month if used daily. *When measuring angles for 8 hours a day with the DT-309LF
- The optional Li-Ion battery will allow for even longer use. *Charging requires the CDC77 charger and EDC113 power cable (both sold separately).
- It is a higher quality product that uses parts common to total stations.
- This is a laser pointer with a focus function that allows you to aim at a pinpoint.
- With a JIS protection rating of IP66, it is environmentally resistant to sand, dust and heavy rain.
Applications
- For setting alignment and angles.
