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

 Hey quabba

I can certainly see the fish if they pass underneath the boat when trolling and can often tell the deckies to get ready on the rods when I mark fish. Same goes for billies when I mark bait on the bottom or elsewhere in the water column I can tell if there are big fish on them using the 585. You won't see the fish though where your lures are. Unless you have side imaging you can pass a school and not know and then get a hookup out of the blue.

i love my 585

cheers

as said above, your sounder

as said above, your sounder looks straight down so unless your lure is hanging under the boat it will be miles from where your sounder pic is.

Remember also that a sounder isnt like a camera, it fires a pulse which rebounds in various strengths or variations which are interperated.

Take an extreme example-lets say you were anchored over a lump. The boat is not moving, rolling or rising on a swell. Your sounder will show a flat bottom with no variation, unless a fish swims under, or you move the boat.
