The Fisherman Strainer is only able to catch fish. It does require bait in order for it to work efficiently. And you can dig up worms with the garden trowel in dirt. Then just stack them in a bait pot and add to your strainer. You’ll have fish in no time!
If you want to collect non-living items then you’ll need a survivalist strainer. They come in many different varieties and thicknesses depending on the type of items you want. So the wider the netting the bigger the items you’ll collect, like stone, clay, and wood.
And the tighter the net will give you more coarse items like dirt, gravel, sand, and gold nuggets.
