I've hunted for 6 days using the S4 lockdown so far this fall. I have been happy with the S4 system but it isn't as convenient as a traditional Bino harness in my opinion. This is because you have to un strap you binos before you can look in them. I can live with the inconvenience because it protects my optics so well. I also like the way the harness straps don't interfere with my pack straps. All in all I would definitely recommend the S4.
