I have been using a Big Game Treestands Groundmax Deluxe blind for the last two years. I use it in specific situations where I cannot use a treestand. Percentage of use between the two would probably be something like 75% treestand, 25% blind but I find each has its own set of benefits.

Below is a link to a journal article I wrote while using the blind last year for spring turkey.
