RE: OWL HOOTERS
I've been usung my own voice with pretty good results for years. However, I tried the Primos Camp Owl the other day and was very pleased with it. You have to blow VERY hard, but it will give you pretty good results. Also, I am able to get some sounds that I can't do with my voice. It is not as loud as I would like, but you can't have everything. I have no experience with the Palmer's tube.
