What this listing puts on record

A stainless steel whistle formed by what the maker calls a precise CNC one-piece process, with high hardness and resistance to cold, heat and corrosion, stated at up to 120 dB, described as high-frequency, sold first as a dog and training whistle and second for camping, hunting and hiking, and hung from a rucksack, a key ring or a neck lanyard.

Sold as a dog whistle first

The title opens with the word for a dog whistle, and the second bullet is a training instruction: the maker recommends pairing the first hundred blows with a treat, so that the dog comes to read the sound as something good. Camping, hunting and hiking arrive in the fourth and fifth bullets, after the animal.

That is worth saying plainly on a shelf of signal whistles, because it changes what the specification is written for. A whistle chosen to be heard by a person and a whistle chosen to be understood by a dog are answering different briefs, and this listing is written for the second while being sold into both.

It sits here because it is a stainless steel whistle that publishes a decibel figure and an attachment — the same three things the rest of this shelf is read on. It is flagged here because the listing’s own priorities are not the shelf’s.

High frequency, with no frequency published

The title calls it a high-frequency whistle. No hertz figure follows — not in the title, not in any of the five bullets. One listing in this hub does publish a frequency, and it is not this one.

What is published is up to 120 dB, matching three other listings here to the number, and, like all of them, arriving with no distance and no method. A loudness ceiling and a pitch adjective are not the same information, and only one of the two is quantified.

Stainless steel, cut from one piece

Stainless steel, formed in what the maker describes as a precise CNC one-piece process, with high hardness, resistance to cold and heat, waterproofing and corrosion resistance. Five of the seven listings in this hub name a metal or a polymer; this is the only one that says how the body was made.

What it does not say is how big it is or what it weighs — no dimensions, no weight, only the words small and light — nor whether there is a ball inside.

Nor does it itemise what comes in the box. A rucksack, a key ring and a neck lanyard are named as places to hang the whistle, not as fittings supplied with it.

    • No dimensions and no weight, so it cannot be set beside the three listings here that publish a size

    Best for: Someone who wants a second whistle to hand over, and who reads the plastic and the cord rather than the decibel line.

    • At a stated 512 g it is the heaviest of the seven liners here, against 128 g at the other end of the shelf

    Best for: Hut and hostel nights where the liner doubles as the only blanket you carry, and where 512 g in the pack is not the number that decides.
