I have used several different brands, and this one always seems to make the 'dustiest' flow of powder that reveals the wind pattern most clearly. Sounds silly, but it's been my experience. I've purchased several now and had friends(?) steal a few when out on a hunt.

Fits well in the Pro-M Harness - some wind checker bottles will not. They should send it filled with powder, though.

transfer 3 of your Smoke in a Bottle contents into this bottle and affix to the FHF Bino Harness and your are golden. If you use the harness, this is a must have!

I ordered this as a replacement for the bottle that came with my bino harness. After two weeks of elk hunting and one week deer hunting I noticed the folding spout started to loosen and I would find half open in my pocket a few days later it fully flipped up in my pocket and had almost emptied. Granted it is intended to be used in the bino harness and not in a jacket pocket, but I didn't expect this to happen. I got so lose it would not stay shut so I had to replace it to have a fully functional bottle that fits in the harness side pocket

Exactly as advertised……perfect!

What I needed. Works well and good price.

Sniffer bottle works like a charm and fits awesome to bino harness

The container was the perfect size for what I was needing for a wind indicator bottle. Definitely recommended

This fits as promised.

Works great…just what I needed. Most of the other off the shelf bottles are to wide to fit in the places I generally wanna stick my wind checker. It fits my FHF bino harness perfectly and being my favorite harness…I'll spend a few bucks on the wind checker.
