Marker 6
Overview
Revolutionising underwater precision
Marker 6 is a low-cost, Ranger 2 USBL compatible acoustic positioning transponder designed for simple target marking applications in water depths up to 7,000 m. It is suitable for a range of applications such as underwater relocation.
Overview
Marker 6 is a low cost acoustic positioning transponder for when a compact design and deep operating capability are important operational factors. It enables targets such as underwater structures, vehicles or instrumentation packages to be marked, located or tracked using a Ranger 2 USBL system – Micro, Mini or Standard.
The instrument incorporates Near Field Communications (NFC) allowing for fast set-up. Its acoustic address can be selected from over 200 unique identities meaning that multiple Marker 6s can be deployed in close proximity to each other without causing interference.
At a glance
- Mark and relocate underwater equipment, vehicles and points of interest
- Compatible with all Ranger 2 USBL systems
- Depth rated up to 7,000 m
- More than 30 months’ listening life (lithium battery option)
- Over 200 unique acoustic addresses
On the backdeck, the address can be quickly programmed into each transponder using a suitable NFC enabled handset (including an NFC enabled Android™ handset with the Sonardyne NFC App) or a dedicated HF Radio Frequency Identification (RFID) reader.
Sonardyne Wideband signal encoding reduces the interference both on and by adjacent Sonardyne and other acoustic positioning systems.
The NFC link provides the ability to enter Marker 6 into a storage mode when not in use, thereby significantly increasing the overall battery endurance.
