- the user is provided with information, in particular optical information, about the presence of an object enclosed in the examined medium via the display 14 and the illuminable sleeve 26.
- the examined measuring point can be viewed directly by the user, so that metal parts, such as nail heads or the like, possibly located on the surface of the wall to be examined can easily be visually recognized and thus do not lead to undesired measurement results which are subject to misinterpretation.
- the opening does not necessarily have to have a round, in particular circular, cross section. Oval, rectangular or even square cross sections for the sleeve would also be possible.
- FIG. 2 shows a perspective section through the locating device according to the invention in the region of the opening 24 penetrating the housing.
- a sensor coil 40 of an inductive metal detector is located in the front part of the measuring device 10, ie, part facing away from the handle 22.
- the sensor coil and any associated electronic components for their control are on a circuit board 42 is fixed.
- the center of the sensor is thus in the center of the coil body 40.

- the outer wall of the housing 12 is formed in the region of the coil center by the inner wall 44 of the sleeve 26. In the exemplary embodiment in FIG.
- the sleeve 26 has a round cross section in order to ensure a good adaptation to the shape of the coils surrounding it. In principle, however, as already mentioned, other cross-sectional shapes are also possible.
- a light source 34 for example light emitting diodes mounted on the printed circuit board 42, this transparent sleeve 26 can be illuminated or not illuminated depending on the sensor data. The shape of the illuminated area also shows the user the sensor position.
- the sleeve 24 which is inserted into the housing 12 of the measuring device and, in the exemplary embodiment according to FIG. 2, is supported on the inside 30 of the lower half-shell 50 of the housing 12 on the housing wall 32, which penetrates the measuring device Opening 24.
- the sleeve 26 consists of a transparent plastic, for example a plexiglass element, in which so-called
- Scattering centers are integrated. Because of these scattering centers, the sleeve 26 has a very good scattering capacity with excellent light transmission.
- a light signal can be coupled into the sleeve 26 by means of a light source 34, which can be in the form of a light-emitting diode 36, for example. Due to the high light permeability and the high scattering capacity of the material of the sleeve 26, the light signal which is coupled into the sleeve at a specific point is distributed uniformly in the sleeve and in particular also is guided to the upper edge 38 of the sleeve 26 formed in the area 28 of the upper side of the measuring device. In this way, it is possible to illuminate the inside of the channel formed by the opening 24 and, in particular, to highlight the area 38 defining the opening on the upper side 28 of the measuring device by means of a light signal.

It is also possible to provide only one or more capacitive sensors in the measuring device and to form the sleeve in the immediate vicinity or within a measuring capacitor. For this purpose, the sleeve could penetrate one or more electrodes of a measuring capacitor, for example.
- the sleeve 26 is located within the coil arrangement 40 in order to ensure that the opening 24 in the measuring device is located in the area of the highest sensitivity of the measuring device. In this way it is ensured that a marking applied through the opening 24 to the surface of a medium being examined overlaps with the position of the localized, enclosed object as exactly as possible.
- the illuminable sleeve thus also serves, among other things, to make it clear to the user at which point of his measuring device the sensor is located and at which point the measurement is carried out exactly.
- the illuminable sleeve 26 allows the user to be informed that an enclosed object has been located. If, for example, a metal object is located in the medium under investigation by means of the inductive sensor, one or more light sources 34 can be controlled based on the detected measurement signal in order to illuminate the sleeve 26. For example, it is possible to flash the sleeve when an object is detected. For example, it would be possible to change the frequency of the flashing signal with the strength of the
- Detector shines as homogeneously as possible when illuminated. Since the user generally views the sleeve 26 from a relatively acute angle, good and uniform illumination of the sleeve is important, particularly in its upper part. In practice, only a small number of punctiform light sources 34 will be mounted on the circuit board 42 for cost reasons. Flat light emitters, which would in themselves enable uniform illumination of the sleeve, are technically more difficult to implement and more expensive, but are also a possible implementation for the light source 24.
- the problem of uniform illumination can be solved by the transparent sleeve 24 is made of a plastic material that contains optical scattering centers.
- the sleeve is advantageously made of "milk glass" to a certain extent.
- a more homogeneous illumination of the sleeve 26 can also be achieved in that the visible inner surface 44 of the transparent housing sleeve 26 is provided with a suitable, rough and thus light-scattering surface structure.
- the sleeve is designed as a plastic injection-molded part, this can be done by appropriately eroding the associated tool surfaces.
- the surfaces 46 of the sleeve 26 facing the interior of the housing on the other hand, it is more advantageous if they are made smooth, which may apply. likewise for the lower part of the outer surface of the housing sleeve which is difficult to see for the user.
- the light emanating from the illumination sources 34 is largely reflected on smooth surfaces and is guided in the direction of the visible upper outer side 38 of the sleeve 26 as in an optical light guide. This function can be improved if these smooth housing surfaces are mirrored with a suitable coating.
- a plurality of light sources can be provided, which also make it possible to couple light of different colors into the sleeve 26, in order to provide the user with a color-coded signal
- a green illuminated sleeve can be used to inform the user that he can safely drill in the area defined by the opening 24 on the examined surface, for example up to a drilling depth indicated in the display.
- the transparent sleeve 26 of the measuring device is also assigned a mechanical task in addition to the display function.
- the locating device according to the invention is not limited to the exemplary embodiment shown in the figures.
- Locking mechanism can be provided which, depending on the measurement signal of a sensor, makes it possible to automatically close the opening 24 penetrating the device.
- a detected object enclosed behind the examined surface could be communicated to the user by means of a corresponding light signal from the sleeve 26, the opening simultaneously
- a mechanical flap mechanism for example to prevent drilling in the area of the localized object.
- the locating device according to the invention is not based on the use of an inductive one
