Could some of you guys post some screen shots of what you're seeing before you start to pull cranks in an area? I use a Helix 7 and am seeing a lot on my screen, but still need some help determining exactly what depth I need to be targeting. I'm letting out the prescribed amount of line and getting my lines close to the water, but still want to know that I'm pulling over schools of fish. Only caught 1 at High Rock Friday in about 3 hours of trolling.
