Had to dig way back in my picture album...but, here's a picture of a double 330 setup with a dive stick. The 330 on the right is tough to see, but it's there.
This picture is from the beaver's view coming into a feedbed that is located in a cutout under a riverbank. The dive stick is just below the surface of the water. The current was fairly swift, so the beavers went under the dive stick....rather than over. Took 2 beavers out of this setup.
Trapped the same situation this season....only difference. 660s and coni holders sure make life easy!! Made up this over-under 660 holder for just such situations
Here's a 660 with a stand and a beaver.
