The Rapala X-Rap XRMAG-30 dives down to 30 feet while trolling. Each lure is tank tested and approved by the Rapala staff and is guaranteed to swim true. The hooks are 4X strong and the hardware is matched so you won&';t loose fish due to equipment failure. We recommend not changing hooks or split rings out as they are perfectly matched for the lure. We sharpen our hooks if they dull but if you need to change them out, they are VMC hooks. You can troll these lures up to 12 knots but we always pull them at 7 to 9 knots. The larger baits like the 20 and 30 size require larger line in the 60 to 80lb range because of the drag from the larger lip. When the bigger fish are holding deeper, these deeper running baits are just what the doctor ordered. 2.5 oz 6 1/4"
