Furuno 585 for trolling
If using a 585 for trolling for macks etc at 4-8knts, should you be able to pick up schools of spanish macks, tuna etc in about 20-30m, and would they look like this pic? (from a youtube vid)
also, when pulling pushers slightly faster, can you see decent fish if they swim up to the lures etc?
cheers for any help
