The Extinguisher deer call: what the ModiSlide actually does

The Extinguisher is a single grunt tube with an adjustable reed, built so one call can cover buck, doe and fawn tones instead of three.

A note on what this page is. We describe how the call is built and where that design helps or does not, using the maker’s own published specification. We do not publish bench numbers or sound measurements, because we do not have a laboratory and would not ask you to trust invented ones.

What is the Extinguisher?

A deer call from Illusion Systems built around a patented sliding reed assembly they call the ModiSlide.

Instead of swapping tubes or carrying separate calls, you move a slide on the body of the call and the reed geometry changes with it. The maker lists more than ten vocalisations from the one tube: buck contact grunts, tending and breeding grunts, doe grunts, fawn bleats, distress bleats, assembly and estrus bleats, plus clicks, pops and roars.

The current version, sold as the 2.0, uses a one piece moulded throat tube and adds a finger groove to the slide. The stated aim of the dual layer throat is directional calling, meaning you can aim the sound rather than broadcasting it in every direction.

How does the ModiSlide work?

One slide changes two things at once: the pitch of the reed and, when it is cold, whether the reed is stuck.

Slide position	Tone produced	Typical use
Toward buck	Deeper, coarser	Contact and tending grunts in the rut
Middle	Mid range	Doe grunts and general contact calling
Toward fawn	Higher, thinner	Fawn bleats and distress

The freeze resistance is the part worth understanding, because it is a mechanical answer to a real problem. Moisture from your breath condenses inside any grunt tube, and in cold weather it freezes the reed solid. On this call, working the slide breaks the reed loose. That is a design decision aimed squarely at late season hunting.

• One slide, three tone ranges, no swapping tubes or reeds
• The same movement frees a reed that has iced up from your breath
• The 2.0 adds a finger groove, so it can be worked with gloves on

Late season is exactly when a frozen call costs you the most, for reasons covered in late season deer and how cold and pressure move the bedding.

Expert tip from Nathan Kestler, Big woods editor: “Every grunt tube I have owned has frozen at some point. A call that can be freed with one hand, without taking a glove off, is solving a problem I have actually had.”

Does one call really cover buck, doe and fawn?

Mechanically, yes. Practically, it depends on whether you would have carried three calls in the first place.

For a hunter who already carries a grunt tube and a bleat can, an adjustable call consolidates two objects into one and removes the moment of fumbling between them. For a hunter who only ever grunts, the adjustment range is capability he will not use.

• Worth it if you call at several tones across the season
• Worth it if you hunt cold weather and have had a reed freeze
• Not worth it if you use one grunt sequence a year and nothing else

Where an adjustable call helps, and where it does not

It solves an equipment problem. It does not solve a woodsmanship problem, and most calling disappointment is the second kind.

1. Decide whether you are calling at a deer you can see or blind calling into cover.
2. Match tone to the phase of the season, not to what sounds impressive.
3. Give one sequence and wait, whatever the call is capable of.
4. Watch the response and let the deer tell you whether to make another sound.

None of that changes with a better tube. Which call to reach for and when is the larger question, and we went through all four types in the best deer calls and when each one actually works.

Expert tip from Curt Bellamy, Public land editor: “A versatile call makes a good caller faster. It does not make a bad setup work, and no product ever has.”

Who it suits

Whitetail hunters who call regularly, hunt into the cold, and would rather carry one object than three.

If that is you, the design answers real problems: tone range without extra gear, and a mechanism that keeps working when the reed ices. If you call twice a season at deer you can already see, almost any grunt tube will do the job and the adjustment will sit unused.
