Thought this might help a few of you save some money. Instead of paying big bucks for a "Ground pod" from the U.S. I did a quick search of the local op shops (actually I found it in the first shop I went into) and came up with this for a quick fix.
I knew what shape etc I was looking for so went straight to the lamp section and found a lamp with a suitable base. The one I got cost me $4 and works pretty well. Not as wide as the ones you see from the U.S. but still does the job of keeping the lens etc off the ground when shooting low at the beach or on mud etc.
Fits nicely in my bag too. Oh, and I was able to re-use the light globe that came with the lamp....waste not, want not
I just ripped the light stem out of the base and had to do a little bit of sanding to make the hole left over big enough to house my tripod head.
You don't need a big lens to appreciate a ground pod either, they would be quite useful for smaller lens as well
Below is the lamp base with my tripod head and 600mm f4 attached
Happy op shopping
