I find the bigger whistles require me to bite down hard to keep them in my mouth and ready. So am ready to get some new whistles but what should I try? Hunt testing but not trialing probably. Yet.
No need to bite on the big whistles. I use a Dallesasse and just have it resting on my lower incisors, holding my teeth/jaw in an underbite. Place the mouth piece of the whistle between your teeth with the lip on the top of the mouthpiece just behind your upper incisors, jut out your jaw and voila! Whistle is balanced, no chomp required. Your lower incisors are the fulcrum, the whistle the load/lever, your upper incisors very little effort!Gooser, I loved the Dallesasse at first. They were better for really long distances in windy or noisy conditions. But I have had to throw two away due to mouth piece being crushed trying to hold them up with my teeth! Plus they take way more air than I've got! I should probably get another for those special days.
I've not tried the 635 but have their T2000 which they claim "the worlds most powerful whistle," and I much prefer the Sonic Blast. Think it's every bit as loud when jumped on but more versatile.Which small whistle do people think is louder for windy hunting conditions, the Fox Sonic or the Acme 635?
