The Ortin is a walk-the-dog top water bait. It features two weight inserts, one on top and one on the bottom. With harder taps, the nose will pop up. With softer taps and/or adding weight to the top, the belly roll is more pronounced. By adding just 2 grams of weight on the top, the bait will almost lay on its side. Adding weight to the bottom will make the bait ride lower in the water. The more weight added, the lower it will run under the water while still maintaining the walk the dog action. The swoosh sound changes depending on how low it runs in the water. http://www.h2otackle.com
