As you have likely noticed, I have recently been investigating the FCC and IMDA listings for Garmin’s next wearable devices to be unveiled. All of us have long been eagerly awaiting the next version of either the Vivosmart 6 or perhaps some additional details about the Cirqa. Today, however, the search has led to an interesting shift from the traditional wearable device territory to the realm of the seas.
While studying the most up-to-date IMDA files for Singapore, I discovered a series of four newly added Garmin model numbers: A04913, B04913, C04913, and A05004.
Whereas the typical reaction within the “leak community” to the appearance of a new ID in the Garmin line-up is to proclaim that it is another watch, the technical nature of the filings tells a completely different story.
Cracking the 04913 Code
These first three identifiers – A04913, B04913, and C04913 – seem like part of the same hardware family. Within the IMDA database, they are clearly classified under both “Marine Products” and “Non-specific SRD” (Short Range Devices).
To take this one step further, I obtained the FCC equipment description for IPH-C04913. While the term “Digital Transceiver” may not seem all that descriptive, the TCB Scope is the clincher – A4 (UNII devices). This means that the device uses the 5 GHz spectrum, which Garmin specifically uses for marine networks with a need for high-speed data transfer (i.e., streaming sonar and radar) instead of the 2.4 GHz Bluetooth/ANT+ used in health wearables.
So, what are they? With the A/B/C SKU breakdown, it seems safe to say that Garmin is introducing an entirely new line of devices – AIS (Automatic Identification System) or VHF Black Box products. The current AIS 800 is an old standby for Garmin products, but these IDs suggest a major update is imminent, potentially with a higher network
The Bluetooth Twist
Strangely enough, when I checked out the wireless capabilities of these devices, I found that although Bluetooth capability was available, there was a lack of conventional Wi-Fi connectivity on some models.
This seems to indicate an evolving strategy from Garmin with regard to the “behind-the-scenes technology” on boats. Rather than using the traditional Wi-Fi connection to link up to the chartplotter, it appears that the newer transceivers are moving towards relying on Bluetooth connectivity for Easy-Pair through the ActiveCaptain app.
What about the “Wearable” Search?
Those of us (count me among that group) who have been hoping to find the Vivosmart 6, I’m afraid you’ve found the right church, but not quite the right pew. You haven’t quite found what you’re looking for, but these products can definitely be scratched off your list of possibilities.
Whereas the A05004, discovered along with the rest of these, may just be an independent piece or “Marine” model of a Networking Hub or GMS Port Expander.
When will we see them?
The FCC confidentiality for these documents is slated to end on July 28, 2026.
It’s all part of the strategy. While Garmin launched its latest marine software package last month, they have been silent about hardware updates. Launching in late July would place the new transceiver and hub devices just in time for the annual summer boat show circuit.
I’ll continue monitoring the FCC for the wearable tech that we’re really after. However, in the meantime, if you’re a seafarer thinking of replacing your electronic equipment, perhaps hold off a bit longer. Garmin’s “Digital Transceiver” is almost here.
