The Primos Hyper Lip Single with Tone Converter (933) is a highly adaptable, open-reed hand call engineered to produce the full spectrum of cow and calf elk vocalizations. Combining a highly responsive bite-and-blow mouthpiece with a removable rubber sleeve, this call gives hunters absolute control over their acoustic presentation. It is a premier tactical tool for coaxing aggressive herd bulls out of thick timber during the archery and rifle ruts.
Why It Outperforms the Competition:
Unlike standard open-reed calls that require precise, difficult lip placement or emit a single fixed volume, the Hyper Lip Single utilizes a patented Tone Converter system. This specialized, slide-on rubber sleeve alters the backpressure and internal airflow inside the sound chamber. With the Tone Converter attached, the call automatically softens your notes and enriches the pitch—making it incredibly simple to produce the gentle, non-threatening mews of a lone cow or the high-frequency whines of an infant calf during close-quarters setups. For windy days or when you need a high-volume locator call, simply pop the rubber sleeve off to expose the full open reed. This allows you to push heavy air pressure directly across the latex to blast intense, loud estrus cries across vast alpine basins. The enclosed bite-strap aligns perfectly with your teeth, providing a clean, sliding scale of pitch with zero artificial squeaks or breaks.

Questions & Answers
Q: What is the main structural advantage of using the Tone Converter sleeve on this elk call?
A: The Tone Converter acts as an acoustic restrictor that restricts the volume and deepens the backpressure. This removes the deep, loud edge from the open reed, allowing you to blow with normal breath pressure while automatically generating soft, realistic, and non-threatening close-range cow vocalizations without over-calling.
Q: Is this call highly susceptible to sticking or freezing up due to saliva buildup in sub-zero alpine weather?
A: No. Because it is an open-reed single system, it is inherently far more resistant to moisture freeze than enclosed reed designs. If saliva or condensation does collect during cold morning stands, you can simply put your lips completely over the reed housing and blow hard in reverse to clear the channel instantly.
