I am thinking of putting a pair of riggers on a new 1750 Lund . I am pretty "green" to the downrigging thing .We are currently using 2 lead core back and dipseys out each side . We bring all our lines in when a fish is on ,but usually leave the dipsey on the opposite side out . Will I be able to leave the riggers down as well? Any suggestions on what type of downriggers I should look at . Manual verses electric.
