The SECO Thunder 56 Laser Detector is best suited for interior elevation and alignment applications. This laser receiver will increase productivity by extending any infrared or red beam rotary laser’s usable range outdoors. An adjustable rod clamp is also included for mounting to grade rods and a built-in magnet for ceiling applications.
Consistent Precision Featuring easy-to-read LEDs and three-display channels, the Thunder 56 laser receiver lights up red for high or low and green for on-grade. Its 0.75 mm detection accuracy also ensures accurate leveling and marking.
Loud Audible Signal This SECO laser detector has a built-in beeper with three distinct audible tones for high, low or on-grade indications. The loud 100-decibel audio signal can be heard on the noisiest jobsites.
Built to Last With an IP-67 rating, the Thunder 56 is dustproof and water resistant. This laser detector fits in your hand, on your tool belt or in your pocket. It also works up to 100 hours using two standard AA batteries and automatically shuts off after 30 minutes to conserve power.
