Super Mag

The Tim Grounds Super Mag holds permanent benchmark status among short-reed goose calls. Developed by the late Tim Grounds, this design helped reshape modern waterfowling by proving that a short reed could produce the full tonal spectrum of a Canada goose without sacrificing top-end crack. Built primarily from dense, machined acrylic, it caters to dedicated waterfowlers who want an authentic, uncompromised instrument rather than a forgiving beginner call.

In the field, the call distinguishes itself through low-end gravel and raw acoustic horsepower. It drops down into realistic ground moans, contented murmurs, and feeding chuckles just as readily as it cuts through heavy wind with sharp, high-pitch greeting calls. That range demands proper hand placement and disciplined air control. Callers lacking solid backpressure fundamentals may find it stiff or unforgiving, but hunters with established short-reed mechanics are rewarded with rapid-fire transition speeds and exceptional control over pitch.

Durability is strictly utilitarian. The thick-walled acrylic barrel and matched insert resist cracking in sub-zero pit blinds and maintain dimensional stability through wide temperature swings. While market trends have pushed toward hyper-specialized boutique calls, this design remains a classic workhorse that balances raw volume, tonal depth, and field-tested longevity.
