The Sonotronics EMT-AR “Accelerometer Transmitter” is designed to provide information pertaining to movement of any animal or target tagged with the transmitter. The EMT-AR contains an onboard 2 dimensional accelerometer. When movement (acceleration) is detected on either axis, the quantity and direction of the acceleration is processed and one of many different possible output algorithms are utilized. EMT-AR ACCELEROMETER BASED ACOUSTIC TRANSMITTER Sonotronics EMT-AR (Angle Reporting) transmitters use an integrated accelerometer to measure and transmit the tilt angle or inclination of attached equipment, enabling real-time monitoring of its orientation. A surface receiver can be used to verify the alignment of instruments such as ADCPs without requiring a diver. With operating lifetimes of up to four years, these transmitters can also mark deployment sites for future relocation. Monitoring is performed using either the USR-23 deck receiver or the UDR diver receiver. Links: EMT-AR Datasheet EMT-AR Manual VIDEOS PRICES

SHP Transmitters Sonotronics Small High Power (SHP) transmitters help researchers track small animals over long distances. Available in 11 mm and 13 mm diameters, they can be used with fish weighing as little as 300 g under the 1.25% rule and produce source levels of 150 dB. Optional sensors provide additional environmental and behavioral data, including activity (accelerometry), depth (pressure), and temperature. SHP transmitters operate at frequencies from 69 kHz to 83 kHz and are compatible with many existing receiver arrays when configured with Open Protocol or R64K coding, and are available for surgically implantation (I) with a rounded shaped end for easier insertion or with endcaps with small holes for external (E) attachment. The following tables outline standard offerings; custom options are also available to extend transmitter life. Small High Power Transmitters Links: SHP Datasheet VIDEOS PRICES

Acoustic Transmitters and Receivers -Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. TRACKING PRODUCTS Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. As an example, recently a transmitter used to tag a fish 14 years earlier was detected by a modern MANTRAK receiver, and recovered on a lake bottom by use of an Underwater Diver Receiver (UDR) used primarily for the recovery of tagged equipment. This flexibility and consistency protects your investment in equipment, and allows for collaboration between groups with different interests: many universities use Sonotronics passive tracking products for long term fisheries studies, while at the same institution, an engineering group uses equipment tracking transmitters to tag submerged electronics packages for later retrieval, and both groups use the same active tracking receivers to obtain real-time information on either fish or equipment location and associated telemetry. Although this equipment is highly compatible, there are some detailed differences that help in particular applications: for example Equipment Marking Transmitters (EMTs) the same internal electronics as passive tracking tags used in fisheries research, the EMTs are housed in rugged, brightly colored PVC, with large mounting holes allowing use of standard zip ties for easy attachment to equipment. Based on the application area, Sonotronics tacking products are divided into 3 areas: Active Tracking, Passive Tracking, and Equipment Tracking.

Our sonic telemetry project to determine the impact of the March 2008 High Flow Event on rainbow trout movement in Lees Ferry was a success because of your and your staff’s determination. We were able to deploy 90 transmitters in rainbow trout, the smallest of which was 157mm. We detected these tags before and after the flow with manual tracking and by using the submersible ultrasonic receivers. Interestingly, tagged trout did not displace downstream during the high flow. Thank you for your good humor and determination through this challenging project!” — Kara D Hilwig “Just wanted to drop an email to say thanks for all your help with our order! We’re really happy with the tags we received and have just begun our deployments. Thanks again! — Clemency” “… Furthermore I would like to inform you of an AWESOME recent finding. One of the 260cm female lemon sharks that was equipped with a Sonotronics 4 year transmitter was detected on our SUR array in Bimini for multiple days at the end of May this year. This shark was tagged in Bimini on May 19th 2007 and has not been detected since then. This shark was therefore at liberty for 2 years and the transmitter was still working on her return to Bimini – MASSIVE THANK YOU to you and all your team.” — Tristan Guttridge, PhD Student, University of Leeds, UK From another happy Sonotronics Customer – “Thank you for taking my call. I always appreciate how well I am treated by the team at Sonotronics and I look forward to doing more good work with you in the amazing years to come!” “Just received the USR-96 receiver … Looks to be working perfectly… just one more reason why your customer service is top-notch.” “We are honored. #customer service ALWAYS a pleasure”. – Dr. Yannis Papastamatiou, @Dr_Yannis The following information has been submitted by researchers who have used Sonotronics’ products in their studies.
