Abstract: An automatic angling machine of the type comprising a line reel, a circuit associated therewith for delivery of pulses in dependence of the rotational speed of the reel, a counter means for recording the fishing line depth, an electromagnetic clutch and an automatic depth control circuit which, in cooperation with the counter means, controls the various functions of the machine by means of the clutch. According to the invention, there is provided a means for activating the automatic depth control circuits and therewith the clutch in order to stop the line reel when the fishing line becomes slack during discharge from the line reel. The means comprises an electric circuit which is connected between the pulse-delivering circuit and the automatic depth control circuits and is adapted to deliver an activating signal when the frequency of said pulses becomes lower than a given value.

Abstract: An apparatus for detaching fishes from fish-hooks on a fishing line during hauling of the line comprises a guiding means (1) disposed below the fishing line (2) and having a guiding edge (10) forming an acute angle with the line (2) in the hauling direction thereof and causing arriving fish-hooks (8) to slide along the guiding edge when passing the apparatus, and a detachment means (11) ccoperating with the guiding means (1) for detaching fishes hanging on the hooks (8) when arriving at the guiding means (1).

Abstract: An angling machine is electronically controlled with a digital indication of the fishing depth by counting the number of revolutions of the winder or reel spool of the machine. The apparatus comprises a converter for connection to the transmitter and the receiver of an echo sounder, a pulse generator and a plurality of counters being included in the converter for indicating the actual depth as determined by the time interval between two signals from said transmitter and said receiver, respectively, and a plurality of comparators coupled to respective ones of said counters for comparing the counts thereof with the counts of the counters indicating the fishing depth. The angling machine has circuit means controlling the fishing functions thereof by correspondence between the counts of the respective, corresponding counters.
