Topcon LS-100D Rotary Detector with "mm / inch" Display

Note: This product only ships to the UK and Channel Islands.

Versatile and designed for maximum user convenience, the LS-100D features a digital readout to confidently deliver elevation and vertical alignment control on demand.
It features an extra-wide beam capture sensor that also rejects annoying interference from strobe light exposures. The large and bright LCD displays (front and rear) feature 9-channels of grade information and digitally show the distance to on-grade. By pressing the Hold button, the display is locked so the user can conveniently read the results. For added versatility, three colored LED’s and a strong magnet mount are embedded for vertical operation, ideal for steel erection or operator grade checking while excavating.

To assist in monitoring the Topcon rotating laser, alert icons appear on the LCD if the instrument is disturbed (HI alert) or when the laser battery is low.

I have worked in the construction industry for over 25 years dealing with hundreds of suppliers, the quality of their products is fantastic, the delivery is next day so you can't complain about that and the customer service is second to none, if you need a leveling tool don't bother going anywhere else.
