Guys, the Depth Hunter Power Pro is what I've been using. It's marked at 5 foot intervals with about a 6 inch section of white with a 1 inch black section in the middle. It changes color every 25 feet. You know exactly how deep you are fishing all the time. Bass Pro had it for a short time, but it is much cheaper on the internet. Scissortail Sports is where I get it. It is also great for trolling, letting you know exactly how much line you have let out.
