Depending on the area we hunt

But we normaly run 2 Mojo's
1- 3'-4' off the water , the other is 8' off the water ( 10' piece of 3/4" TW conduit added to the stand painted OD green )

At first light they are killers
But after a hour or 2
We watch , some days they will cause the ducks to not finish
So we sometimes turn them off

This happens a lot more when a group or 2 of other hunters that can't hit SH!T are using them close by

We always have jerk strings out

Along with 2 remote controlled geese
I took a goose shell , cut 2 layers of 2" blueboard to fit inside
Cut a opening in the Blueboard to take a remote controlled boat

When we get bored or want to make some water move
We will drive the goose around and thru the decoys
Works great and the ducks love it
