DESCRIPTION

Mesh Networking creates near-limitless connections
Mesh is a self-optimizing and self-healing network, always looking for the best connection and seeking a new one when a device disconnects. Tufftalk M features two different Mesh modes: Open Mesh and Group Mesh. With Open Mesh, a near-unlimited number of users can connect within an effective range of 1.1 km (0.7 mi). For private sessions, Group Mesh supports up to 24 participants. Tufftalk M also features a 4-way Bluetooth intercom to connect to Sena’s Bluetooth-equipped devices.

Hands-free communication thanks to full-duplex technology
Worksites need communication lines open for safety reasons. Being able to respond without needing to press a button is essential, especially for people working with heavy equipment. Tufftalk M helps with these issues by utilizing full-duplex technology, a system that allows people to talk hands-free. Crews can easily communicate and keep their hands free of any distractions while working.

Hearing protection and communications solutions for high-noise environments
The Tufftalk M headset provides hearing protection while letting you communicate in loud, busy worksites. The headset comes in two styles, each with their respective noise reduction ratings: over-the-head earmuffs (26dB) and hardhat integrated (24dB). It’s designed with safety and comfort in mind with a hands-free intercom system and a three-button layout making it easy to control.

Stay in control with the Sena Smartphone App
Connect the Tufftalk M to the Sena Smartphone App and instantly be able to customize the headset. Change settings like turning on Mesh Intercom, adjusting channel frequency, set up speed dial options, program FM station preferences, and more.
