Measurement Modes
The Bozily B1 offers multiple measurement modes to suit various golfing situations:

Mode 2: Flag-Lock with Vibration
Designed for easily locking onto the flagstick. In this mode, aim at the flagstick and press the Power Button. The device will quickly identify the flag and provide a precise distance. Once locked, the rangefinder will vibrate to confirm the measurement, ensuring you have targeted the flag and not background objects.

Slope Compensation (ON/OFF)
The B1 rangefinder includes a slope measurement function that automatically calculates the incline/decline to provide an adjusted distance, accounting for elevation changes. This feature helps in selecting the correct club for uphill or downhill shots.
- To enable slope compensation, slide the Slope ON/OFF Switch to the "ON" position. The display will show an indicator that slope is active.
- To disable slope compensation (e.g., for tournament play), slide the switch to the "OFF" position. The device will then provide only the direct line-of-sight distance.
