It can also be made to be irradiated with light.

The frequency of the variation survey unit 430 may follow the intention of the measurer, and it is preferable to change the frequency according to the frequency suggested by the measurer.

In the case of the detachable indicator unit 300 of the depth measuring system having a selective attachment function by improving the fixing strength according to the present invention, the external measuring unit 100 is in contact with the sum of its own weight and the human force from an external force. It is possible to prevent the detachment of the detachable indicator unit 300 while maintaining the .

The force of the pressing unit 320 pressing the upper end of the barrier unit 111 due to the weight of the detachable indicator unit 300 and the force forming the attractive force with the interlace unit 110 through a magnetic optionally provided are summed and can work.

For example, if the detachable indicator unit 300 is fixed only by attraction by magnetic force, it cannot cope with problems such as weakening of the attractive force and the fixing force may be reduced. It is possible and the fixing force can be improved by the pressing force of its own weight.
