Don't know......have found them to flare birds. Now these were geese in a field (there were ducks around too) as I had heard they are okay for geese, but proved that wrong. Worked fine in the marsh for mallards...then again sometimes they will come to anything. So not sure yet....will have to do a test when the birds are coming in of a spinner vs. the flyer on their own.
Mojo's will scare geese every time in the field when they are turned on. I have all my spinners and vortex on the same remote control, that way I can turn them off when the geese are locked onto my spread!
True enough....however, other forums, and I believe the edge site itself claims not to flare 'em with the flapping action vs. spin. Either way no go. Had it wired to remote but for some reason it wouldn't shut off and had to just take it down. Disapointing.
