Abstract / Hauptanspruch
A depth gauge comprising an elongate support (1) which is intended to be in an upright orientation when in use, a multiplicity of emitters (2) mounted on the elongate support (1) and being spaced apart therealong, and a multiplicity of detectors (3) mounted on the elongate support (1) and being spaced apart therealong. The emitters (2) and the detectors (3) are electrically connected to a processor to enable the latter to send signals to the emitters and receive signals from the detectors.

According to a first aspect, there are at least two sets of such emitters (2) or at least two sets of such detectors (3) mounted on the elongate support (1). The sets are directed in different respective directions.

According to a second aspect, each emitter (2) is capable of emitting radiation, and/or each detector (3) is capable of detecting radiation, selectively within a plurality of different ranges of frequencies without emitting/detecting radiation outside the selected range. Alternatively, emitting/detecting radiation outside the selected range only at a reduced level compared to the radiation emitted/detected within that range. Alternatively, different emitters (2) are capable of emitting radiation, and/or different detectors (3) are capable of detecting radiation, within different respective ranges of frequencies without emitting/detecting radiation outside those ranges, or emitting/detecting radiation outside those ranges only at a reduced level compared to the radiation emitted/detected within those ranges.
