X-Tag
X-Tag


Dimensions Max. Diameter: 1.3 in (3.30 cm)  x  Length: 4.8 in (12.19 cm)
Antenna: 7.3 in (18.54 cm)
Sensors Temperature, depth (pressure), light level, battery voltage
Construction Composite carbon-fiber, low-drag housing constructed with a strong tether attachment point. A polycarbonate BigEye™ nose cone encapsulates the multi-directional light sensor array, while the shape-memory alloy (NiTi) antenna provides additional durability. The PTT is then coated in a layer of anit-foulant paint to inhibit biological growth.
Example species sharks, eels, striped bass, Atlantic salmon, Atlantic halibut


Standard Rate Programming

Features

  • Predefined pop-off date or deployment duration (up to 12 months)
  • Calculated geolocation data
  • Transmitted time-series depth and temperature data
  • Transmitted daily minimum and maximum light-level data
  • Emergency Depth Release (greater than ~1250 m*)
  • Constant Pressure Release after 2 days*
  • 15,000 Argos message transmission capacity (about 16 transmission days)
  • SiV™ technology
  • Temperature-compensated real-time clock
  • Embedded CRC checksum with bit error detection
  • Rated to 3500 psi
  • Complete archived (2-minute interval, high-resolution) depth, temperature, and light-level records upon recovery and data extraction

These tags are designed for smaller marine species and suitable for both vertically active and demersal species. Sunrise and sunset times are determined from tag-recorded light levels and used for daily geolocation (latitude/longitude) estimation, allowing for track reconstruction and understanding of migration pathways. Standard Rate X-Tags also provide depth (pressure) and temperature readings at 15-60 minute intervals, depending on deployment duration.


High Rate Programming

Features

  • Predefined deployment duration (up to 30 days)
  • Transmitted time-series depth, temperature, and light-level data
  • Emergency Depth Release (greater than ~1250 m*)
  • Constant Pressure Release after 2 days*
  • 15,000 Argos message transmission capacity (about 16 transmission days)
  • SiV™ technology
  • Temperature-compensated real-time clock
  • Embedded CRC checksum with bit error detection
  • Rated to 3500 psi
  • Complete archived (1–6 minute intervals, high resolution) depth, temperature, and light-level records upon recovery and data extraction

These tags are designed for smaller marine species and suitable for both vertically active and demersal species. High Rate programming is intended for short-term (<30 days) projects, such as post-release behavior and mortality studies. Temperature, depth (pressure), and light-level data are recorded at a high sampling rate with readings every 1-6 minutes, depending on the programmed deployment duration. Please note that High Rate programming does not provide calculated geolocation data. Low-resolution light-level data are recorded to identify potential predator ingestion events.
