Construction:

The Grizzly tree stand is aluminum tubing that has been welded together, rather than some of the conventional riveted platforms we've seen from other manufacturers. It looks solid and strong so far. Next, we followed the detailed instructions and bolted on the hardware and seat support tubes with a few basic tools to complete the assembly process. No problems there. The seat folds up nicely against the platform, allowing you to have a nice package that'll strap somewhere onto your ATV. Using all aluminum materials gave this large portable tree stand a good lightweight approach--only 17 lb.
How'd it perform? After arriving at our hunting location, we strapped the Grizzly onto our back with the included backpack straps, which were even adjustable. Walking and scouting through the forest for a place to set up the stand was pretty comfy, even though we had the Grizzly on our back.
Once we located what we thought would be a productive area, we selected a medium-sized tree to perform Operation "Clamp-on". As with ATV riding, our concern for safety (we really want to make it home each night) is the most crucial detail. We opted to mount the Grizzly just four feet of the ground to check it out before venturing higher up the tree (do this at home if necessary, but practice mounting the stand at lower elevations).

While holding the Grizzly at approximately a 45� - 90� angle, wrap the rubber-coated chain snugly around the tree, then place the chain over the Grizzly's platform and hook the free end of the chain onto the Grizzly's platform bolt. Now push down on the front of the Grizzly's platform until it's firmly in place against the tree. Check and make sure that the chain isn't too loose or too tight. If so, readjust accordingly. Next, lift up the seat, wrap the 1000-lb. test nylon strap around the tree to secure the seat upright.

Since we were only a few feet above the ground for testing purposes, we decided to forego the safety strap from our body to the tree at this time. After climbing up onto the Grizzly's platform, we arrived at a very stable "safe feeling". Weighing in at around 180 lb., I spent a good deal of time standing on the very corner of the platform, trying to make it break or shift positions on the tree--NO GO! More than likely it's because of Bear River's patented Cam-Lock system. After leaning, sitting, twisting and jumping on the platform, NO SQUEAKS! Bear River's lucky because it guarantees that this big bad Grizzly won't sound like a mouse.
