My trainer uses this whistle and recommended it to me for my lab. I was using an orange gonia whistle and my dog wasn't hearing it when he got 80-90 yards away on a blind retrieve. When I switched to this whistle, the difference was amazing. The sound carries MUCH father and it doesn't now my ears out. Couldn't be happier with it.

Great whistle! I own several and the sound on all of them is very consistent. Well made. GDS is second to none! Great company! Great people!! Great customer service!!!

This whistle was recommended to me by my Dog Trainer when picking up my finished pup (Black Labrador retriever). We hunt primarily flooded rice and bean fields and occasional close work timber holes. Can't say enough about this whistle. I really like the shorter hunt test version just for space saving on my calls lanyard. Dog is very responsive with it. Came quickly from Gun Dog Supply and well packaged. Thanks!

Good for mid to short range, will work for long range also but have to put some air to it.

They are load and the dog can hear them in the wind way out there

Great whistle fast delivery will be ordering more products

Nice crisp sound carries well

Used them for years. Loud for those long marks and blinds

My 8 month old GSP had no issues transitioning from a traditional pea whistle to this one. It’s super loud and sounds great. Our first day out with NAVHDA it was a 20mph wind day and this thing was the tool for the job. Everyone needs one.

Great whistle to use for training. This item was recommended by 3 different trainers and I was not disappointed.

I bought this for closer dog work. After switch to the 5� version of this whistle for working Field Trial set ups. Less cumbersome.

I like the size for hunting but I wish I would have got a different color for that instead of the blue. Sorta sticks out. Works great in cold weather. A lot easier on my ears than a regular whistle

Awesome whistle.

Range of volume that can be produced with this vs. the whistle previously used. Not as comfortable if you are one that keeps it between the teeth for long periods every day but worth the slight discomfort for improved performance.

Love it the tone is very close to the field trial whistle.

Somewhat difficult to blow. Often slips out of teeth while handling the dogs. Will probably be okay once I get use to it

The whistle is ok but after being trained with a pea type whistle my dog would not respond to this one. Totally different sound. I need to return it.

Good whistle! Great fast service!!!

Great tool to add to anyone's training program! This whistle is great for high windy days when your dog is 100+ yards ahead of of you.

Haven't used it in the field yet, but it doesn't seem very loud.

Great whistle.

Compact and smooth. Great sound for the size.

I like the sharpness off this whistle. It carries well in all diverse weather conditions.

Haven't had a chance to use it in really high winds, but so far it's worked great.

Haven't used it yet. Pup's at retriever training, and that's what the trainer uses.

Sounds ok. A little hard to keep in your mouth and give commands at the same time. But you get use to it.

Works almost as well as the Field Trial Whistle.

It might just be that the whistle I got is a bit off the standard for this model, but the sound of it seems thin to my ears and seems to get lost when there is much of a distance involved. I like how the shape of it protects my ears, but tend to use my pea whistle more often because the dogs seem to respond to it better. I also like how it fits in my mouth and is easy to grip, but I think I might like it better with a rubber sleeve on it - I've been thinking that I might put an elastrator bad over the end of it to make it softer and more meaty and more likely to be retained (hang) on my lower teeth when I'm talking to my dog, but since I don't use it that much, I haven't taken the time to try it.
