are there any offshore maps out there w/ good bottom detail? i'd like to go cod fishing east of the bank and i'm having trouble finding a map w/ any detail. the only time i've been east is on charters and i'm jonsing for some cod and pollock

Here is one of my favorites, I can look/zoom/pan on this for days and have. Good luck out there and let me know how you do.

Niko,
Depending on your chartplotter, you may be able to get a chip.
I got a bathemetric chip for Garmin.
Raymarine calls their fish & chips.
