Milltech Marine Take
The X100 represents a genuinely new direction from em-trak, and while it looks promising on paper, it’s important to be clear about what that really means.
This platform hasn’t been out in the wild yet, so it hasn’t had the chance to be beaten up by weather, vibration, installs, and real boaters doing real things.
That’s not a criticism, it’s just the reality of any first-generation product.
If the Vesper Cortex taught us anything, it’s that real innovation in marine electronics doesn’t come from rebranded commodities.
It comes from small, focused teams willing to take risks, spend years testing and breaking things, and accept that early generations are rarely perfect.
A lot of lessons only get learned once equipment is actually onboard and being used.
em-trak has a strong engineering background, and the X100 looks like a serious attempt at rethinking how VHF and AIS work together in a single platform.
It’s early, and there will almost certainly be things learned once these are out in the field.
Whether that’s a reason to wait or a reason to lean in really comes down to your comfort level.
Integrated Loudhailer and PA
Built-in loudhailer and public address support for onboard safety announcements,
maneuvering assistance, and crew communication.
One-Touch DSC Calling
Simplified DSC operation enables rapid distress and direct calling without excessive
menu navigation, designed to be usable under pressure.
Real-Time AIS Transmit and Receive
Continuously transmits your vessel’s position and receives AIS targets in real time,
improving situational awareness and visibility in busy waterways.
Space-Saving Single-Unit Installation
Combines VHF, DSC, and AIS into one compact fixed-mount unit to reduce helm clutter,
simplify wiring, and streamline installation planning.
CONNECT-X Wireless Command Mic
Use your smartphone or smartwatch as a wireless command mic. Make and receive calls, monitor VHF/DSC,
view AIS traffic, and receive alerts from anywhere onboard.
Private Crew Intercom
Create a private onboard intercom between CONNECT-X devices for crew communication without broadcasting over VHF.
MOB and AIS-PLB Alerts
Receive MOB and AIS-PLB alerts on mobile devices with recovery guidance, so you stay informed even away from the helm.
Overview: VHF, DSC, and AIS — Engineered Without Compromise
The em-trak X100 is a fixed-mount marine communication and safety system that blends a Class D VHF/DSC radio
with a high-powered 5W Class B SOTDMA AIS transceiver, wrapped in a rugged, water and weather-proof design.
It is built for boaters who want reliability, modern wireless control, and practical safety features that work in real conditions.
What Makes the X100 Different
- Clear-Wave digital audio for enhanced speech clarity
- Sunlight-readable full-color display
- Wi-Fi and Bluetooth connectivity
- NMEA 2000 and NMEA 0183 integration
- Built-in GPS with optional external antenna support
- Internal zero-loss antenna splitter for simplified installations
- Flexible mounting options for a wide range of vessels
- Designed for long-term use in harsh marine environments
CONNECT-X App: Freedom to Command Anywhere Onboard
Life onboard is rarely confined to the helm. The X100 is designed around the way people actually use their boats:
moving between cockpit and cabin, stepping forward to handle lines, or relaxing at anchor while still wanting awareness.
CONNECT-X provides VHF/DSC/AIS visibility and control on your phone or watch, and can scale with your vessel’s Wi-Fi for coverage throughout the boat.
Remote Awareness
- Monitor AIS targets from anywhere onboard
- Receive navigation and safety alerts remotely
- View MOB and AIS-PLB alarms with recovery guidance
- Maintain situational awareness away from the helm
Practical Communication
- Make and receive VHF and DSC calls from mobile devices
- Use smartphones and smartwatches as wireless command microphones
- Create a private onboard intercom between CONNECT-X devices
- Broadcast vessel-wide communications when required
DSC Made Practical
DSC is most valuable when it is easy to use under pressure. The X100 supports features designed to keep calling practical,
including AIS target calling, group calling for events or coordinated cruising, and test calling so you can confirm your setup before leaving the dock.
AIS Performance: 5W Class B SOTDMA
The X100 includes a 5W Class B SOTDMA AIS transceiver designed for strong performance and intelligent slot scheduling.
Silent Mode provides operational control when needed, including timed behavior.
MOB Awareness That Reaches the Crew
The X100 supports MOB device enrolment and can deliver alerts across connected devices, helping the crew stay aware even when not at the helm.
