I used a doe in estrous one during rifle season, and i pushed down the button and it went of for like 5 seconds then stopped, so i messed around with it for a little bit trying to get it to work and got pee all over my hands. I would stick with tinks or something along those lines. I would like to say I had a button buck walk right up to it and smell at it for 5 minutes or so. I know they are often curious, and am not saying that is what brought him in, but if a big one would have just stopped to smell it for 5 seconds i guess it could work.
