Primos makes a very simple and good one...you can order it through Bass Pro, I think. I have used it for a few years now.

 

i use the quickstand bow stand...bought here on AT! its a great stand and keeps my bow in the perfect position. it is a little cumbersome to carry. but well worth it.

i hunt were there is a lot of rock in the ground....so a stick in stand....wouldnt do me much good

 

I have tried the metal stake type holders and really am not impressed with em. They usually run under $10 but, I have had a bow fall out of them 3 times or have had a hard time getting them into solid ground so I opted not to use em.
Laying the bow on a mat or the case to the groundblind while inside the blind seems to work for me, if I don't just sit there with it on my lap.

 

I use the Ameristep Doghouse blinds while bowhunting from the ground and I simply tied a hook into the roof where the roof poles cross. I hang my bow on the hook and it stays there until I am ready to shoot. No muss no fuss.

 

I tried one of the primos deals...didn't hold the bow very well...placed my order for a QSA, jcmorgan has them I think...

 

You have to check out the new stand by HawgLite!

 

I have one that I haven't used yet but, be this weekend hoping it works good. Otherwise I use to just lay it on the ground

 

Bow Jaws makes a great bow holder for ground blinds. It uses a double stake with a square base so it won't tip over. The universal piece detaches from the base with a button spring and you can use it with your platform base or screw in tree base.
You can go to www.bowjaws.com to take a look.

It works with ALL bows!

Here's a couple pictures of the screw in tree base and treestand platform base along with the ground blind bow holder.
