Hadn't been here in a while so when i saw a review of David's PacSeat I had to go along for the ride. I've had mine now for about 2 seasons. I hang with a bunch of GA trad shooters and a bunch of them fellas told me it was a good seat. I think I saw one of nutters youtubes with it as well. I'm a relatively new hunter, 4th season and I have never killed anything out of a stand. Ground blinds or just on the ground or in the seat.
I have not had a single problem with the pacseat. I use it for long hike in mountain hunts where I am highly unlikely to hang a stand and prefer the ground hunt with a ghillie and the ability to move, a lot, to find the few game animals that roam the areas I hunt. I actually had a bear brush up against my ghillie late last season, after I'd tagged out on bears.
I've attached some cheap backpack to it very easily and in that I have a water bladder and various other things a fella might need in the woods for a day of hunting. I have hauled off two black bears and one time I hauled off two deer, quartered up, at the same time with this. The one and only complaint I have about this thing so far is that the backpack straps are abysmal for a pac. They are just two layers of wider webbing and with a 100 pounds back there... they dig in real nice!
I am glad to hear they are expanding and growing and that they stand behind their product. I've never had to contact customer service, but glad to know they are legit.
Also, I have heard of guys wearing the system backwards if they kill something and simply using the seat as a makeshift shelf, I haven't tried it, but it sounds like it could work. But if you have half dozen decent webbing straps and some game bags... you going to be alright getting that stuff off the mountain.
