Raintalker: Waterproof Walnut Box/Purpleheart Paddle
This call is made of a walnut box with a Purpleheart paddle. It never needs chalked and is hyper- low maintenance. Other waterproof boxes run in the rain, but ours sounds just as good wet as it does dry. It's a staple to everyone's vest that is trusted to get the job done right.
Do not use chalk or sandpaper on this call as it will ruin the integrity of the waterproofing.
