This photo shows a rivet-on 12 guage shell holder that is available in the Accessories area of this site. We used standard aluminum pop rivets with a backing washer to fasten this part to the Hypalon portion of a sternum strap harness. The holder grabs shells well, so a downward or even upside down mount is secure. This one is mounted on the hunter's left side, slanted down so the right hand can easily grab the shells while the gun is held in the left hand, for right handed shooters.
This photo shows another phase of the same shell holder mounted to a belt loop to fit 2" belts. On any WingWorks vest, this part can replace the 2" loop used as a strap retainer. There's plenty of room in this part to slide your strap end through. The shell holder is made to lean out forward so it's easier to grab the shells. This item is also available in Accessories. Here are a couple of photos of vests set up with a few of the page 1 details and others. XL and XXL vests have room for belt mounted pouches, knifes, multi-tools and cameras. The 2 camera cases are by Case Logic, and both attach with an opening velcro strap, making threading and unthreading a non-issue. The blue case on the shoulder strap fits the slim new Olympus digitals and other similar. It is the only Case Logic we've found that fits a vertical strap, but it easily attaches to both of the harness styles.
The Hunter Orange vest is an XL, and it easily accomodates a larger Case Logic horizontal strap case on one side, and a Custom Leather Craft (CLC) tool pouch capable of holding a GPS or cell phone, multi-tool and pocket knife. Many digital cameras will fit these pouches too. The belt keeper 12 ga. shell holder replaces the 2" loop fitting on this vest, and there are a few items in the shell pocket front pouches like flashlights, hemostats, game shears or a fork to flip cactus bulbs off the dogs.
Another typical fall item is a light fleece jacket or windshirt cinched into the strap on the upper rear gamebag. Also the shell pocket flap on the hunter's right sides are velcroed inside the pockets for fast shell access (a lot of people don't get this right away so we mention it a lot).
The khaki vest shown is a Large with the small camera case attached above the hypalon harness patch. The patch also has the rivet-on 12 ga. shell holder mounted so a right hander can reach across body and pull shells down and towards the open breech.
Grouse and woodcock hunters in heavy cover may be able to get by on water in the game bag pouch and unthread the outer bottle holsters for a slimmer profile in the thickets. It takes a few minutes to remove and reassemble but why carry what you don't need.
We get a lot of questions about what to do with the great variety of transmitters for electronic collars. We've used transmitters on our off-shooting shoulder for years, especially the round TriTronics units held on with bicycle tube rubber bands, or more recently large rubber "O" rings for a cleaner look. Velcro doesn't have a lot of hunting fans, but it works to hold the lighter units out of the way if it's fastened well and a good grade of Velcro is used (they usually need a lanyard as well for extra protection).
We're offering some electronics holders in Vest Accessories to handle the Garmin Rino and Astro, either on the off shoulder harness strap vertically, or between shell bag and game bag on the XL and XXL vests' 2" belt. "D" rings can be added to the off shoulder sternum strap hypalon patch to hold a variety of transmitters upside down or upright depending on the unit and holster. Another option is to sew an extra layer of webbing above the hypalon patch to slide in the metal clip on many of the smaller transmitters.
Coyote Leather Company has a nice line of leather transmitter holders for a variety of units that ride upside down hanging off the belt. We recommend these on our XL and XXL vests between the shell and game bags. They're well made, are easy to access and use, and are out of the way when you don't need them. If you don't see what you need on the site, phone them and discover how many different transmitter holders they really make. Their printed catalog is more up to date than the site.
The stash pockets on the shell pockets are great for cell phones and other smaller devices, like pistol clips and multitools, or a tube of gun oil. The side zip pockets on the game bag easily hold Spot Locators, wallets, licenses and keys.
There's a local company that builds an accessory vest for all sorts of electronic gadgets from cell phones to GPS units. They have a patent for wiring clothing from pocket to pocket to facilitate the gadgets. Maybe bird vests will eventually be pre-wired for a more ergonomic use of e-collars, GPS, walkie/talkies, cell phones, personal locator beacons, headphones and hearing protection.
We've heard that a few companies are working on combining some of the modern functions into "super transmitters" that will simplify life for the walking hunter somewhat. Less gadgets means less interference in the hunting experience, and a less complicated vest too.
