Dog whistle
Now that is interesting... How well does that work for ya' as compared to other locator calls?
The one time I want to use a locator call is when I roost em', or setting up in the morning... Owl call works in the morning, but does not seem to work in the evening as well... The hawk call has worked out for me mid-day, but I would like to hear more about the dog whistle (I am assuming it is the high-pitched "silent" whistle)?
