FLEX II 4G Max Transformer[1]

The CF series is an evolution of the FLEX II 4G Max, featuring

elevated solar panels (one or two) to accommodate thick feathers.
Pictured to the right are the FLEX II 4G CF1 (top) and FLEX II 4G
CF2 (bottom) models.
Constructed from nylon using 3D-printing technology, thehousing surpasses waterproof standards with a rating exceeding
IP68.

FLEX II ARGOS
FLEX II Argos provides both GNSS data, and Doppler locations estimated by the Argos system. Additionally,
it is equipped with multiple sensors capable of generating data that reflects ambient environmental conditions
and animal activity and behaviors.
In addition to scheduled Argos transmission, FLEX Argos utilizes patented INTELINK® technology to transmit
data to smartphones or Debut series gateway devices. This facilitates ground search operations, retrieval ofdata stored onboard (often exceeding the capacity for Argos transmission), and enables real-time modelingbased on raw acceleration data downloading and tagging using specialized tools.

external antenna. By switching from the default 0.4mm titanium alloy wire antenna to a 7*7 braided rope madeof titanium alloy wire, the total weight increases by approximately 1 gram.

TRANSMISSION STRATEGYFLEX Argos monitors Argos satellite pass and attempts transmission only when a satellite is over head. Thismode is particularly recommended for long-distance migrating species, but it is also advisable for other4 / 7

species when you are unfamiliar with satellite pass schedules in the tracking region.
A crucial parameter is the "GNSS queue," which determines how many of the latest GNSS data points should
enter the queue for Argos transmission attempts. Since Argos transmits one piece of GNSS data per time
following a 90s/60s periodic pattern during satellite passes, and the device does not confirm whether thesatellite has successfully received it, setting an appropriate GNSS queue value ensures that you receive thedata as complete as possible.
The GNSS queue should be configured considering the GNSS interval you set, as well as the satellite passduration of the region (the longer the pass, the more data can be transmitted). A successful example is at asouth latitude of 38°, for seabirds with favorable solar charging conditions, where GNSS data was collected
every 30 minutes, and the GNSS queue was set to 20. In this scenario, the researcher can receive 42~48
non-repetitive GNSS data points per day.
If another transmission strategy is required to suit the study's scenario and objectives, such as periodic or ontime transmission, please contact your sales manager for configuration assistance.

ACCESSORIESFLEX II series is primarily engineered for back-mounting using harnesses. However, it's also adaptable for use
with a set of accessories referred to as "transformers," allowing for alternative applications such as neck-collar
usage.

BACK-MOUNT
Each device will be provided along with 2 meters of 5mm wide UHMWPE tape (for harness use) and 6
aluminum rings (for binding the harness) for free.

NECK-COLLAR
Injection-molding collars at 38/43/55 mm diameter areprovided at the price of USD 6.99 for each.
If you need different collar diameter, please contact us forcustomization using 3D-printed structure.
