SUR SUBMERSIBLE ULTRASONIC RECEIVER Sonotronics proudly introduces this new addition to available fisheries research technologies. This rugged, inexpensive, long life unit allows for detection of fish passage within its detection area. Strings, arrays, or individual receivers can be utilized depending on the resolution of detection desired in the study. One of the main principles behind the SUR is its ability to save valuable field time, potentially reducing project costs. The SUR brings new features and options to the marketplace aiding in the continued development of fisheries research technologies. Features 1. Frequency scanning – large numbers of unique transmitters 2. Ability to detect transmitters also used in manual tracking 3. Backwards compatibility with all Sonotronics transmitters 4. Ability to determine presence of data in the SUR without retrieving the receiver – “ping and response” 5. Ability to interface with a variety of communication systems: cellular and wireless 6. Long battery life: >12 months with typical configuration 7. Saves valuable time in the field reducing manual tracking hours The SUR is simply moored using the eye bolt on the bottom. Its natural buoyancy will keep the unit upright in the water column. Transmitters within the units detection area will be logged to the on board memory along with date and time. The SUR can be interrogated remotely for the presence of data, allowing it to be left alone with no data hits. Data is then downloaded via the serial port. The SUR is a stand-alone submersed unit which allows for detection and logging of the same transmitters used in manual tracking, including any Sonotronics past or present transmitters. The SUR is a scanning receiver allowing for transmitters on different frequencies to be logged, also allowing exclusive channels for specialty transmitters. The SUR’s available ping and response transponding allows researchers to “ping down” to the SUR on a separate frequency, asking it to “ping up” its status, which can be detected with a manual tracking receiver. The SUR transmits a ping sequence related to the presence/absence of data in its flash memory. On many projects, this can save field time as the units do not need to be retrieved to determine data presence. Accessories, Options, Ordering SUR22-BLE : This is a stand- alone device consisting of a battery system, microprocessor, 2Mb of flash memory, real time clock, hydrophone, ultrasonic receiver, and Bluetooth connectivity for wireless, high- speed downloads and configuration. SIT-01 : This is the SUR Interrogator Transmitter. This a 60kHz transmitter with a specific pulse rate used to interrogate SUR’s for the presence of data. Only one SIT is needed to service multiple SUR’s. SURBAT : This is a replacement battery for an SUR Links: Datasheets SUR SURsoft Manuals SUR SUR-22BLE Software Downloads 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
