S4 Gear Lockdown X Optics Deployment System Review - S4 logoWhat is the S4 Gear Lockdown X Optics Deployment System?

The S4 Gear Lockdown X Optics Deployment System is a chest harness that holds a pair of binoculars securely against your body in the ideal position to quickly and quietly retrieve them when needed. Sometimes you need your hands free for other things and have to allow the binoculars to hang by the neck strap. This works great as long as you are sitting perfectly still. However, the moment you start moving the binoculars start swinging around and banging into things. Try climbing into a tree stand with binoculars hanging around your neck. Or worse, picking up something off of the ground. Unless you are a skilled contortionist it is likely that the binoculars will swing forward and smack into something the moment you lean forward. If you are hunting or bird watching, this could scare away the animal you are watching. Worse yet, unrestrained binoculars may be broken.

Who needs the S4 Gear Lockdown X Optics Deployment System?

Anyone that uses binoculars and doesn’t want to deal with the binoculars swinging and bouncing around as they move around may find the S4 Gear Lockdown X useful.
I tested the S4 Gear Lockdown X Optics Deployment System at Boy Scout Camp while serving as an Assistant Scoutmaster for R-man’s Troop. The first thing the Scoutmaster said when he saw me wearing the S4 Gear Lockdown X  was “Are you going bird watching?”. Well, no. I was just wearing them around camp with my ATN Binox-HD digital day/night binoculars (click for review) to see how the S4 Gear Lockdown X felt and whether it held the big smart digital binoculars securely. However, I could easily see this being useful for bird watchers, boaters, sports fans, racing fans, or anyone that ever uses binoculars and needs to be mobile.

There are two basic parts of the S4 Gear Lockdown X:

1) Binocular holder to secure the binoculars when not in use.

The heart of the binoculars holder is an aluminum backer that gives support to lock in the binoculars and protect the top of the binoculars from impacts. The aluminum armor is held in a sewn-in channel in a backer of thick rubberized fabric. The binoculars side is padded with a soft cloth-backed neoprene on the inside, and covered in a RealTree camo print on the outside. When binoculars are stowed the bottom of the Lockdown X folds up around the binoculars lenses and is secured to a hook on the top via an adjustable bungee cord loop. There are two tri-glide adjustable straps sewn into the top edge and one plastic connector on each side, all for connection of the binoculars holder to the X-shaped harness.

2) Breathable X-shaped harness to hold the Binoculars holder against the wearer’s chest.

By “x-shaped” I mean that when spread out, the top and bottom straps look like an “X”, with the shoulder straps up top and the waist straps down below. The arms of the “X” are layers of breathable mesh and fabric covered in RealTree camo fabric. The center of the “X” omits the camo cover to allow more ventilation.

The height of the S4 Gear Lockdown X on the wearer’s chest can be adjusted via tri-glides on the straps at the bottom of the shoulder straps, while the elastic waist straps are also adjustable to adjustment for wearers with more or less girth around the mid-section. I am rather tall and thin, and had no problems adjusting the S4 Gear Lockdown X to fit me.

How to scare away deer and birds

I didn’t grow up hunting. My Father took mef dove hunting when I was in high school, but took the following two decades off.
So, while others were developing hunting skills and figuring out what hunting gear worked best for them, I was doing other things.
Fast forward to my first season deer hunting.

While sitting in a tree stand about 22 feet off the ground I thought I spotted something moving on the other side of the field in the shade. At a bit over 200 yards it wasn’t clear if it was a deer or something else. So, I reached into my utility pouch (I call it “the junk drawer”) for my binoculars. While removing the binoculars from the pouch I also inadvertently pulled out the Primos doe bleat call and a rattle bag. Both of which fell about 18″ before the tethers caught each one and they swung into the metal deer stand making a rather loud racket. Loud enough that the deer nearly 200 yards away on the other side of the field took off before I could get the binoculars up to my eyes to get a look a it.
If only I had a better way carry my binoculars instead of stuffing them in my utility pouch… and THAT is why the S4 Gear Lockdown X Optics Deployment System interested me.

I wore the S4 Gear Lockdown X Optics Deployment System to secure my big, heavy ATN Binox-HD digital day/night binoculars while walking, running and sitting. The Lockdown X worked very well. There are a number of clever details to enhance the experience and make the S4 Gear Lockdown X more comfortable. I have not yet subjected them to a full hunting season’s abuse. They appear very well made of durable materials. I will be rather surprised if there are any durability issues, but will update this review if there are any issues to report.

Gear Score
S4 Gear has taken the basic idea of securing binoculars and run with it. If you carry a decent set of binoculars, then protecting them with the Lockdown X Optics Deployment system is a no brainer.
