01 · The Basics

Understanding Full Duplex Communication and the Eartec Evade Advantage

Full-duplex communication is technology that lets users talk and listen at the same time. Unlike traditional radios, this creates a natural conversation flow similar to a phone call, no waiting for a gap in transmission or a "roger" beep before responding.

The Evade series is a completely self-contained digital wireless system that doesn't require a bulky base station or external wires, making it highly portable for field use.

The technology behind the connection

Evade headsets use 2.4 GHz frequency hopping technology, automatically switching channels to avoid interference, critical in busy NZ ports or industrial sites where radio congestion is common.

Main-Remote architecture: one headset acts as the "Main," relaying signals for up to eight "Remote" units.
Integrated antenna: housed inside the ear cup, eliminating the risk of snagging on gear or vessel rigging.
No base station: headsets link automatically without any central hub to fail or go out of range.

Push-to-talk (PTT) systems are a liability when both hands are required for vessel control or equipment operation. The Evade system keeps the microphone live at all times, allowing for instantaneous warnings, removing the physical act of pressing a button lets team members focus entirely on their primary task.

02 · Core Features

Core Features of Eartec Evade Headsets for Industrial Use

The full-duplex nature of these headsets is the primary advantage for local teams. Unlike traditional walkie-talkies requiring a PTT button, Evade allows simultaneous conversation, vital for crane operators, marine crews, and search and rescue teams who need both hands on their equipment at all times.

Durability and environmental protection

NZ's maritime environment is demanding on gear. Salt spray and high UV can degrade standard plastics quickly. Evade headsets feature a ruggedised exterior that resists moisture, and the fold-flat design lets crews store several units in a compact locker without risking damage to the boom arm. We recommend a simple freshwater wipe-down after exposure to salt spray as good general practice.

Audio clarity and noise suppression

The Evade uses noise-cancelling microphone technology to filter the constant drone of engines and wind, isolating the human voice so instructions are heard correctly the first time. The Auto-Mute feature is a standout, flipping the microphone boom arm up instantly cuts the user from the loop, useful for Coastguard teams who need to speak to someone on deck without broadcasting that conversation to the entire crew.

Battery reality: field-replaceable lithium-polymer batteries provide up to 8 hours of continuous operation per charge. For 12-hour shifts in remote NZ locations, carrying spare batteries is more practical than waiting for a unit to recharge, they swap in seconds without tools.

Choosing between single-ear and dual-ear models depends on the job role. Single-ear headsets suit supervisors who need to stay connected while remaining aware of their physical surroundings. Dual-ear models provide passive noise reduction, the preferred choice for engineers working near pumps or generators. A tailored assessment from our team helps prevent costly mistakes when selecting the right configuration for your site.

03 · Marine Applications

Eartec Evade in Action: Why It Suits NZ Coastguard and Marine Teams

Operating in NZ's coastal waters requires equipment that survives more than a light spray. Traditional communication often relies on shouting or hand signals, which fail the moment visibility drops or engine noise peaks. During a tow operation, a skipper must maintain a visual on the disabled vessel while coordinating with deckhands, a standard marine VHF radio's push-to-talk action takes a hand off the helm or the tow line at exactly the wrong moment.

With Evade, the skipper, deckhands, and rescue swimmers speak simultaneously, just like a standard phone call. When a deckhand has both hands on a wet mooring line, they can give a "line clear" confirmation instantly while maintaining their grip, removing dangerous guesswork during technical recoveries.

NZ's air is notoriously salt-heavy and humid, which degrades consumer-grade electronics quickly. Evade headsets feature sealed internal components designed to withstand this environment. While no headset should be submerged, the moisture-resistant padding and housing are built for the spray-heavy environment of an open-air RIB. For a tailored assessment of your vessel's requirements, contact our technical team.

04 · Beyond the Water

Best Suited Applications: Beyond the Water

The Evade system excels wherever split-second timing and constant voice contact are non-negotiable. When a tree surgeon is working at height operating a chainsaw, they don't have a spare hand for a radio, Evade provides a permanent open channel that lets ground crews warn of immediate hazards without delay.

Construction and heavy industry

Safety on NZ construction sites depends heavily on clear communication between crane operators and dogmen. During blind lifts, where the operator can't see the load, the full-duplex nature of Evade allows for continuous verbal guidance, avoiding the clipped first syllable common with traditional PTT radios. For larger sites requiring coverage across several hundred metres, integrating these units with two-way radio systems provides a hybrid solution covering both close-quarters precision and site-wide logistics.

Production and event coordination

NZ's film and television industry demands equipment that's reliable and simple to deploy. The plug-and-play design means crews don't waste time on frequency pairing or base station setup, letting sound and camera teams coordinate movements instantly. Event organisers can pair these headsets with Portable Communications equipment so internal staff and public address systems stay synchronised.

05 · Scaling

Selecting and Implementing Your Eartec System

Selecting the wrong model often leads to premature hardware failure. If your team works in the rain or near heavy machinery, the ruggedised build is the standard choice, avoiding the cost of replacing light-duty gear that wasn't built for the task.

Scaling your system: a simple two-person pair works for crane operators and dogmen. For teams exceeding five members, a multi-port charger keeps every battery ready between shifts while the system itself scales to nine users (one Main plus eight Remotes) without any degradation in audio quality. Mix single-ear and dual-ear models freely, dual-ear for high-noise engine rooms, single-ear for supervisors needing situational awareness.

Buying communication gear is an investment in safety and operational efficiency. Our team understands the RF challenges found in NZ's rugged terrain and steel-heavy industrial sites, and if a headset takes a hit on-site, we can often repair it locally rather than requiring a full replacement. Contact Mobile Systems for a professional assessment of your team's needs.

Frequently Asked Questions

Common questions about Eartec Evade headsets

Do Eartec Evade headsets require a base station or licence in NZ?

No. Evade headsets use an all-in-one design where the transceiver is built directly into the ear cup. This lets your team communicate without bulky external equipment or recurring licensing fees from Radio Spectrum Management.

What is the range and battery life of an Eartec Evade system?

Up to 350m in open, line-of-sight conditions, and roughly 8 hours of continuous operation on a full charge. Range will decrease with heavy concrete walls or thick metal obstructions between users, and for longer shifts, spare batteries swap in seconds without tools.

Can I mix single-ear and dual-ear headsets in the same system?

Yes, freely, to suit different roles. A team leader might use a single-ear model to stay aware of surroundings while deckhands use dual-ear models for better hearing protection in high-noise areas. All models sync together seamlessly.
