You can micro-tune a drift as well. Use a wider zoom level because the boat will be moving and you'll want to keep the structure on the screen as you head for it. A 1/2-mile zoom should work fine. Again, pick the wreck, reef, or temperature break you want to fish, and place the cursor on it. Next, proceed upwind, upcurrent, or a combination of both that you think will put you on a direct drift back to the cursor. When you get far enough off, shut down, mark where you are with an icon, and drift. Check to make sure the boat's icon and cursor are still on the screen. If not, zoom out to the next level.
