I have a smaller boat and fish K-Bay often for Halibut, I am curious if I am doing something wrong. I mark fish on my radar so thats usually where I start my drift and usually pick up a few smaller fish but nothing over 50lbs. Is there a depth or any structure that I should be looking out for? I have been told you can't see halibut on a fish finder but I figure if there are fish on the screen there is a chance for a halibut. Can anyone help?
