Scotty Black Box, digital w/Pulse Mode
Scotty 1201 Black Box digital with pulsing mode includes wiring harness and stainless steel contact sleeves for two downriggers. The Black Box controls the voltage on the cable, maintaining the productive fishing range of positive 0.1 volt D.C. to 0.9 volt D.C. on up to six downriggers. The Black Box can be operated in the continuous voltage mode, or the "pulsing mode" that cycles the charge on and off every five seconds - often triggering a strike.
