Pucker up and hang on! The seductive sounds of the HOT LIPS™ will fire 'em up! Many times, you will call in cows who will bring in the herd bull. The lead cow is very competitive and will often come to ward off cows competing for her bull's attention. The HOT LIPS™ with Tone Converter™ reproduces the sound of two cows in estrus simultaneously competing for the herd bull. The Tone Converter™ is perfect for when they come in close to bring them in those last few yards. Herd bulls can't resist our HOT LIPS™. Features: Dual open, single-reed setup achieves higher pitch of multiple cows. Tone converter allows you to produces mellow and softer tones so important for calling in those call-shy bulls. US Patent No. 5,910,039.
