Hi warwick,
Yes I was getting lots of slashes behind the popper with zero connects. I've caught maybe 5 or 6 now all on the back treble, just in the lip. I guess they are trying to disable or even annoy the popper rather than eating it, which is clearly impossible given the size of their mouths.
If I'm looking for a feed of whiting I have been using the popper to prospect as you can cover a lot of ground quickly, then swing over to bait when I've seen them having a go at the popper, not very sporting I know.
Also caught some decnt flathead...and a big green toad.
Surprisingly I've had heaps of gar have a go but no hookups.
