Recommendations for buyers

✓
Magnification Power
Ensure the telescope offers at least 30x magnification for clear readings at long distances, especially for large-scale construction sites.
✓
Display Configuration
Opt for models with dual-sided LCD screens; this allows the surveyor to read measurements from both sides of the instrument without repositioning.
✓
Battery Management
Select models that use rechargeable lithium-ion packs but also include an adapter for standard AA batteries to prevent downtime in the field.
✓
Compensator Range
A wide tilt compensation range (typically +/- 3') is vital for maintaining accuracy even when the tripod is set on slightly unstable or uneven ground.
