Products
Hand pick products and tailor your data collection system with Thelma Biotel transmitters, receivers, and software.
Transmitters
Acoustic tags for tracking underwater movement and activity. Designed for a range of aquatic environments and use cases.
Configurable 6 - 16 mm Transmitters
Thelma Biotel transmitters are energy-efficient and versatile, designed for studies of aquatic species and underwater equipment. They come in five sizes: 6, 7, 9, 13, and 16 (based on diameter in mm). They can be tailored in length, power output, and battery life to fit your needs. They are used in wildlife tracking, aquaculture monitoring, and equipment monitoring. Whether you need an off-the-shelf solution or a tailor-made design, our transmitters can be configured for your exact requirements.
XP56
Acoustic sensor transmitter for continuous monitoring of subsea installations over extended amounts of time. XP56 has a large and robust casing equipped with batteries to exceed an operational time of 7+ years. The XP56 can be fitted with multiple sensors, including depth (pressure), temperature, and tilt.
Receivers
Reliable receivers for collecting acoustic data in the field. Explore recievers for mobile tracking or long-term deployments.
TBR 800
The TBR 800 is a robust, low-power digital acoustic receiver operating at 63–77 kHz. Used with Thelma Biotel transmitters, it supports customizable code sets. Paired with the DeckBox, it can send status updates on battery and power use.
TBR 800 Release
TBR 800 Release is a robust, low-power digital acoustic receiver operating at 63–77 kHz. Used with Thelma Biotel transmitters, it supports customizable code sets. It features an acoustic release module that can be triggered when paired with the DeckBox
TBR 800 Release Deep
The TBR 800 Release Deep features a motorized release three times stronger than the standard version, ensuring reliable operation under high pressure. The release is triggered acoustically from the DeckBox.
Live
Live is a digital, multi-frequency receiver (63–77 kHz) with precise millisecond-level timestamping for fine-scale positioning. It instantly transmits detections via RS-485, and its compact, rugged design makes it ideal for harsh environments where space is limited. Designed with a strong focus on energy efficiency, Live can operate directly from your field laptop or run for months - or even years - on small battery packs.
Link LoRa
Link LoRa gives you instant access to critical underwater data. Watch detections unfold in real time, track live sensor data, and download complete datasets as they are generated. Deploy multiple nodes equipped with Live receivers and Link LoRa units to cover entire areas, with each node having a transmission range of up to 5 km.
Accessories
Optional components to support deployment and recovery. Built for practical use in field conditions.
Focus - Directional Amplifier Field Kit
The Thelma Biotel Focus – Directional Amplifier Field Kit is a precision-engineered acoustic reflector that fits seamlessly over the standard Live transceiver. It delivers powerful signal amplification within ±15° of your target. Designed for use with the DeckBox, the Focus extends your operational range and pinpoints the bearing of any acoustic transmitter. It is essential for maintaining a safe communication distance when working with the TBR 800 Release – Deep model, and we recommend it for all Release receivers operating at depths greater than 200 m.
Mooring Recovery System (MRS)
The MRS (Mooring recovery system) consists of a single spherical buoy that fits over the receiver and provides the buoyancy to let it rise efficiently to the surface once the release mechanism is triggered. The buoy is made of a rugged polyethylene shell filled with synthetic foam tailored to the required depth. The foam backing ensures the float will never puncture and lose its positive buoyancy, implode, or crumble from the sustained pressure. It will neither soak over time nor carry pressure to the surface. It has a bright yellow color to make it easy to spot at sea. The buoy is designed to flip 180° at the surface for better visibility and to keep the transducer submerged for acoustic ranging.
DeckBox Field Kit
The DeckBox is a versatile topside kit for manual logging of acoustic transmitters, retrieving TBR 800 Release units, and performing status checks on deployed equipment. With its rugged, waterproof tablet and our free LiveView software, you get flexible, real-time control and monitoring right in the field.
Software
Tools for managing, viewing, and analyzing your telemetry data. Developed for use with Thelma Biotel systems, and support easy export to third party software.
LiveView
LiveView is the Live tracking and data visualization software delivered by Thelma Biotel. It provides live streaming of acoustic data to your computer or with the Deckbox field kit. LiveView is used as a visual reference when starting and stopping transmitters, for active tracking, communicating with deployed TBR family receivers, and calling up acoustic releases.
ComPort
Upload, view and analyse your tracking data quickly and easily with Thelma Biotel’s software, ComPort. By using the built in Bluetooth connection on the TBR 800, uploading substantial amounts of data is seamless and fast. With ComPort’s many viewing options, visualizing and understanding your tracking data is easier than ever.
