The 4D Line Thru Trout has been designed with a wider inner line passage, so it's now easier to change your leader. It is supplied with a Carbon 49 leader, as well as the Line Thru Modifier accessory. The details of the 4D Trout have been improved and are now touching on perfection, its ultra-lifelike S-shaped swimming action combined with the detailed real trout scan skin and the built-in attractant make it an incredible lure!
