By downrigger weights used the fishing line is held with the bait at the desired depth. If the fish has bitten, the fishing line is released from the trigger terminal and the catch can be landed. The offer ranges from the smallest, portable downrigger, suitable for salt Bass Heritage engines or equipped with counter and high power electrical downrigger. In conjunction with the CannonLink Humminbird the operation of up to six Digi-Troll is incredibly easy.
