Portable anchors?

[tipup]

I have been looking and have not been able to find a certain style anchor for my portable house. I seem to remember a type that was spring loaded and was inserted into a hole drilled into the ice? I thought I saw them at Cabelas and Fleet Farm last and now I can not seem to find them. Any help would be great, thanks in advance!!

I think you are talking about the strikemaster anchor, tho it wasnt really spring loaded. You have to spread it out manually. they are about $20 if I recall. Work great
