Acoustic telemetry resources, papers, and information on how to choose transmitters for your study. Resources Depth or Temperature Telemetry Product Comparison A datasheet which shows the comparison of Sonotronics products associated with Depth and Temperature Telemetry Understanding Sonotronics Unique Pinger ID Algorithm A document which explains the algorithm used by Sonotronics for the unique ID of transmitters. Custom transmitter labels Email us to customize the labels in your transmitters. This allows you to leave a visible message that shows through the clear wall of the transmitter telling anglers, etc. where they can send the transmitters if found How to choose transmitters for your study Consider the following when choosing the appropriate transmitter. Size – The commonly used rule is 1.5% – 2% of the animal weight in air is maximum allowable transmitter weight in water . Exceptions to this rule are sometimes made by biologists in the case of robust species, crustaceans, and other animals that are determined to be able to hold a larger transmitter. Lifetime – It is recommended that a lifetime that is 125% of the actual length of the study is used. This allows extra room at the end of the study, and helps guarantee a high output from the transmitters throughout the study. Range – It is recommended that the highest output transmitter available that fits in the necessary lifetime and size categories be used. This guarantees greatest ranges in both automatic and manual tracking. Keep in mind that a number of factors in the environment can limit range. Telemetry – There are a number of telemetry options available on Sonotronics transmitters. Temperature, acceleration (used for feeding and mortality), depth, and tilt. These options are chosen based upon the data desired in the study. The Don L. Brumbaugh Memorial Equipment Scholarship The Sonotronics’ Equipment Scholarship, established in 2005, commemorates Donald L. Brumbaugh’s pioneering work in the development of fisheries and wildlife biotelemetry technologies. The scholarship is designed to aid students in fisheries research projects. Read more…

UDR-Kit The UDR-kit contains all of the basic tools necessary for locating pingers from a surface vessel and while diving. This includes the UDR receiver, external hydrophone adapter, directional hydrophone and useful accessories, housed in a rugged Pelican case. The UDR-Kit Includes: · UDR Receiver · UDR-BNC adapter · DH-4 Directional Hydrophone · Test Transmitter · Waterproof Pelican Case · Underwater headphones · Auto Power Battery Cable UDR: A narrow band Underwater Diver Receiver allows detection of transmitters from 30kHz to 90kHz, and displays the unique identification of individual transmitters. Transmissions from pingers are presented as an audio output and details displayed on the integral LCD. Several modes are available from detecting simple pingers, to decoding and displaying ACT coded transmissions and associated telemetry as well as R-code IDs. A received signal strength indication may be displayed to allow precise bearing to tagged equipment. DH-4 Hydrophone: A directional hydrophone designed to maximize range and provide directivity for locating transmitters. Other Accessories: A test transmitter included in the kit allows the user to test the equipment and the environment to determine expected range. The headphones and speaker allow for different methods of listening for transmitters. The auto power battery cable allows for the UDR to be powered and charged by a ‘cigarette plug’ outlet, while the extra battery pack allows for longer use when internal power is used. Options: External compass. Links: UDR-Kit Datasheet UDR Manual VIDEOS PRICES
