An indicia-bearing guage is mounted in a watertight housing and is driven in reduced proportion to an external pulley by a gear and pinion assembly within the housing. A manually positionable index is disposed on the housing to engage a detent projecting from the gauge and to move along with it without hindering the gauge rotation. A manually positionable stop is also disposed on the housing to engage the detent, but the stop serves as an impediment to the movement of the gauge. A slip connection is provided between the gear and pinion assembly and the gauge so that the pulley can continue to rotate if a substantial force is applied to the line while the detent is being hindered by the stop.
