Leica FTA360 – 779301 - The Tripod adapter for easy and precise targeting
Measuring over long distances requires a stable set-up of the laser distance meter. It is often
  difficult to fine adjust the laser dot at the target point by holding the device to a stable reference or
  if mounted on a tripod by moving its head.
  We have addressed this problem and introduce a new tripod adapter with fine-adjustment for easy
  and precise targeting. This new adapter fits with our Leica tripods TRI70 and TRI100. Use it with
  the new Leica DISTO™ D810 touch which has a special reference setting for this adapter as well
  as the Leica DISTO™ E7500i, D5 and D8 (correction of the reference point is via Offset setting).
  The existing adapters TA360 and LSA360 are not for use with the new D810 as the D810 is too
wide. These adapters are still viable for other DISTO models.
