looking for most effective and productive ways to catch bass in pits with very little structure? any ideas would love to hear some..Thanks

Points , flats, grass,  depth ?

bout 20 acres the size no flats no grass runs 20-40 ft deep all the way around shapped in a horseshoe..... has lots of bass 90 percent of the bass in my albums are from there but I feel like I could be catching more

Drop shot

I fish a 41 acre sandpit, it has a little more going on than yours, but one of the very effective ways of covering a lot of water and catching fish is the C-rig.
