Settle an argument re: anchors

[Isaguel]

I do need an anchor that works better than the mushroom anchor I use now. Just so I am clear, is this what you are referring to as a box anchor:

ANd quick question, it seems most of the posts suggest this works beter in muddy or rocky bottom. WHat about bottoms with vegetation or sunken branches and other obstacles. Is there a risk of it getting stuck and unable to pull out. Should we have 2 different types of anchors depending on the lake we plan to go to. We have many lakes in Minnesota some are rocky sandy, some are very rich in vegetation and other bottom objects.
