We use 3 of the spinning wing decoys (one Mojo, one Lucky Duck, one Air Lucky), and 2 of those "vibrating" decoys, and I've thought about one of those RC decoys as well. The problem is, I hunt a lot during the week, when my two weekend partners have to work, and it's pretty hard to use one when alone... what with the dog handling, calling, etc., who will operate it? I've only got two hands.
I've tried encouraging one of my weekend partners to buy one (he can't blow a call worth a hoot, and has nothing else to do while a flock is working our dekes), but he's content with what we've got (and too cheap, too
). I won't invest the bucks in one if I can't use it when hunting alone, which is about 50% of my hunting time.
I've also thought about one of those little propeller things you clamp on the keel of a regular decoy, making it swim in a circle. Much cheaper, and makes more sense to me.
Last season was absolutely the worst season for ducks I've ever had. Still got shells left from my first box of Black Cloud #3s. We've had a pretty severe drought for 4-5 years now, and our two best spots are all but dried up. We switched to laydown blinds and field dekes, which worked real
well on geese. We hammered the geese, but very few ducks were attracted to the dried up, now grass covered, lake beds. Black Cloud BBs worked well, too.
Edit: I haven't put my duck boat in the water, nor used any floating decoys, for the past two seasons. Rather than spend any money on a RC duck, instead, I've had to buy a laydown blind, field decoys, and a "deer" cart to haul it all out into what was once covered by water.
