Will this laser level work for checking panel gaps on a car body?

Yes. The straight line mode projects a horizontal or vertical beam to verify panel alignment and reveal gaps. The cross mode is useful for corner checks on doors and fenders.

Do I need batteries, and are they included?

Battery requirement and inclusion status not confirmed. Contact support to confirm power type before purchase.

Can I use the laser level outdoors in sunlight?

Laser visibility outdoors depends on ambient light. Use indoors or in low-light conditions for best laser projection clarity.
