I've fell victim to the "duck call buying bug" too many times looking for that perfect call. I've ended up with a bag full of calls that I never use. I have a couple of RNT calls, a BGB call, several ECHO calls (that, by the way are very easy to use), several Primos calls (which are are also easy to use). But the only call that I've found that actually stands up to it's waterproof claim is Cuttdown calls. I hunted at Peach Point WMA about four years ago when a cold front blew through. I was laying in the mud on the south side of a football sized water hole, trying to take advantage of cover the saltgrass provided when it came through. The wind kicked up to about 30 mph and blew all the water to my side of the pond, so I was then laying in about 6 inches of water. Wasn't about to leave or sit up above the grass though, because the birds wanted to hit the water. My calls were hanging down into the water, and my Cuttdown calls were the only calls I could simply pick up out of the water and blow with no problem. They have acrylic and wood calls priced from 30 to around 70 bucks or so. Maybe a little higher now, haven't had to buy one in a while. They are easy to blow as well. Soft quacks to screamin high balls, they do it all. You probably will need to order directly from Cuttdown though, haven't seen too many places that carry them for some reason. Sorry for the long reply. Hope this helps.
Fishing was invented to pass the time between Duck Seasons....either duck hunt or get outa my boat!!
