UDR UNDERWATER DIVER RECEIVER Relocation of a Marked Site Low Visibility Equipment Relocation Sonotronics, Inc. offers an Under Water Diver Receiver that allows a diver to approach an object or animal marked with an ultrasonic pinger*. The UDR can achieve ranges exceeding 1km, while still allowing relocation in zero visibility. The UDR comes with waterproof headphones and has variable gain control to maintain good signal strength and directionality during approach of the target, as well as volume control and a backlit display. The UDR is user programmable for frequency and gain ranges. *The UDR has been used in field research for locating pingers manufactured by SONOTRONICS as well as others. Specifications Length : (From Display to outer rim) 16cm Width : (At outer rim) 11cm Height : (Bottom of Handle to top of unit) 20cm Weight (Air) : UDR: 900g, Headphones: 415g Sensitivity : 20uV, (S+N)/N = 30dB Frequencies : 30 to 90 kHz Controls : Gain control, volume control, frequency control. User can preprogram the unit before the dive for a variety of applications. Autonomy : 8 hour battery life on fresh recharge Accessories Bonephone Optional Bonephone headphone piece can be used in applications where a wetsuit hood is worn, with the earpiece inserted into the hood next to the ear. This can be useful in cold water and high noise environments. When ordering, the Bonephone can be requested as a replacement to the standard headphones, or can be ordered as an additional accessory.

IBT SERIES MINIATURE TRANSMITTERS Range up to 500m+ IBT-96-1, IBT-96-2, IBT-96-9 IBT-96-9 (shown) Notes The typical rule of thumb is to use transmitters that have a weight in water that is 1.5 – 2% of the fish weight in air. Weight in O2 (air) is put only as additional reference. All dimensions for internal implant. Mounting holes for external use available upon request. Links: VIDEOS

MODEL DH-4 DIRECTIONAL HYDROPHONE The DH-4 provides the greatest range and precision in locating transmitters from 30kHz to 100kHz. The parabolic reflector provide 16db of gain over a comparable omnidirectional hydrophone, and yields a calculated DI of nearly 25db, reducing the effect of environmental noise. The DH-4 is the primary hydrophone for manual/active tracking. Sensitivity: -84 dBV ref 1 uBar (-184dBV ref 1 uPascal). Beam Width: +/-6 degrees at half power points. Shaft Length: User supplies mounting shaft. (1 inch PVC) Output: BNC connector. Cable: Replaceable 10’ RG-58 C/U. Links: DH-4 Manual VIDEOS

MO: MODULE ONLY GENERATORS CHP-MO-HP Sonotronics is now offering versions of its acoustic transmitters as modules that use external power sources. The CHP-MO-HP may be mounted on an instrument package or underwater vehicle, taking advantage of existing onboard power sources. The 2 wire version of the CHP-MO-HP will begin transmission of a coded sequence as soon as power is applied, and alternatively a 3 wire version is available that allows separate transmit control. Key specs: 16mm (dia) x 40mm (length) External Supply: 2.8V-5.5VDC 75ma max, 2ma ave Frequencies: 32-40kHz, 69-83 kHz, crystal controlled Source level: up to 150db re 1uPascal @ 1m EMT-01-3HP-MO 32mm (dia) x 85mm (length) External Supply: 4.5V-15VDC 500ma transmit Frequecies: 32-40kHz crystal controlled Source level: up to 165db re 1uPascal @ 1m 4 wire (1m water blocked, jacketed cable) V+ = Red GND = BLACK Control+ (C+) = Orange GND = Brown Operation: with power applied to Red/Black, C+ open = off, C+ to GND = transmit

MODEL TH-2 TOWED OMNIDIRECTIONAL HYDROPHONE The TH-2 provides a simple method for mobile active tracking: its small size and hydrodynamic shape allows for trolling at speeds up to 5 knots, while the long cable length minimizes the affect of engine and prop noise. Eyelets allow attachment of small weights or diving lures to ensure the hydrophone is kept at depth while trolling. This design, though simple, rivals more elaborate and expensive systems in actual field trials. Sensitivity: -100 dBV ref 1 uBar (-200 dBV ref 1 uPascal) Beam Width: Omni-directional +/- 2 dB. Output: BNC connector. Cable: 50’ RG316/U. Links: TH-2 Manual VIDEOS

DT AND IBDT TRANSMITTERS – DEPTH TELEMETRY Sonotronics’ depth telemetry transmitters transmit their depth by varying the pulse interval time between pings. For example, a tag at 0psi at the surface may have an interval time of 650ms, and a full scale pressure of 100psi with a corresponding interval time of 2050ms. Depth transmitters come in 50, 100, 200, 300, and 500psi models. The accuracy of these transmitters is +/- 2% of full scale. Depth Telemetry Transmitters IBDT: Range up to 1km+ DT-97: Range up to 3km+ Links: VIDEOS
