· Maintains performance even in rainy, dusty and other harsh job site and weather conditions
· Durable design reduces downtime due to drops and tripod tip-over
· Minimizes power costs, increases reliability with choice of rechargeable or alkaline batteries
· Increases flexibility with optional remote control slope option
Applications:
· Checking/setting elevations, concrete forms, footings, and foundations for small- and medium-sized jobs
· Basic slope work such as driveways and ramps
· Excavations, digging footings and septic tanks
