Cut Vest & Tracking/Trainer collar combination

All I hunt are big catch dogs that are caught for much much longer than a lead in CD. Sometimes they will catch over a mile out. I have to have a good working set up to find them and to ensure no snags or destruction of tracking collar which is also a training collar/shock collar. I have had a lot of collars destroyed by pigs hooking the collar or bitting it while the dog is caught when running the collar under the neck. Usually this results in 1 collar being ruined every 3 or 4 months on average. I now run a vest that has a protective pocket built into the side of the neck part if the vest. In two years I have not had 1 problem with ruining a collar in this vest. It's a little hard to get your finger in to turn the collar on or off and not so easy to slip collar in and out with the long training prongs but I have learned little tricks that make this easy.
To make holes for the training prongs I simply mark where the holes need to be then heat a little metal rod with a torch then press the cherry red end of the rod into the collar portion of the vest where I have marked the spot where the prongs will be. When holes are made I then take a knife or little belt sander and smooth up the inside of the collar from where the material has melted and created a ridge around the hole you just made for the prongs.
I run barknforbacon vests. Doubt that's the style of vest you would want on lead ins but you can go to their website and look at the plates untill you see the add in feature I'm talking about. I'm sure other vest makers here in the US have similar stuff but I'm not familiar with them anymore so don't know for sure. I'm sure you could get one of the makers to build this feature if they didn't offer it as a common add on if it is something you like and want to try
