ABSTRACT:
A depthometer useful for underwater diving is constructed with a cup-shaped casing, and a rotatable transparent cover that is sealably snap-mounted to the casing and closes the front of the casing. The transparent cover houses an indicating pointer that rotates about an axis of the casing as a function of external pressure, and moves along the scale of a stationary dial. The indicating pointer cooperates with a maximum-indicating pointer by way of a dragging member that communicates with both pointers. The dragging member is idly supported by an axially bored member which extends through the cover. The axially bored member cooperates with an adjustable friction clutch and thereby also serves to support the maximum-indicating pointer. The construction of the present depthometer permits the cover to be snap-mounted to the casing without adversely affecting the water-tightness of the instrument.
