Description

The model AT1810 is a complete, single frequency Underwater Acoustic Transmitter that you control. It is easy to use and takes all the work out of putting together a stable and reliable acoustic source for applications such as Through Water Signaling and Remote Control.

The unit is powered by a simple 12 volt battery or DC power supply. The transmitter is keyed on by applying a positive voltage to the control wire and therefore allowing the user to control the duty cycle (On-Time) from zero to continuous. Controlling the transmitter is accomplished by using a simple switch, electronic circuit (i.e. 555 Timer), pulser, computer or any number of other devices or sensors.

Current stocked frequency is 37.00 kHz. Any frequency between 32 and 45 kHz is available for this model at no additional charge. Other frequencies are available.  Standard cable length is 25 ft. (7.5 m).  Contact us for delivery on custom frequencies or available options.

Purchase Includes:  Model AT1810 Transmitter, Instruction Manual, Storage Box and One Year Warranty.
