I finally made a decision and ordered a Garmin. Primary Arms had a $60 bonus bucks deal and their mil discount made it a good deal.
I plan on using it for my crossbow as well as rifles, and the Labradar a guy at the gun club uses seems to miss a LOT of shots, where 99% of the Garmin reviews...
The time at start was a few years ago.
Now, finding primers to get started with makes it almost break even with buying.
But, as others said, you don't save any money, you just shoot more......
As others have stated, it's the wind blowing the snow that separates the 3 season from the 4 season.
Full coverage vestibule/fly that goes to the ground helps a lot.
