Stingray Echo-Sounder (Instrument / Transducer)

A classic NASA boat instrument. The device has a rotating light pointer. It is robust and easy to use. With the gain (amplification) controller, the display can be quickly and safely adapted to ground conditions.

The NASA Stingray sounder has 2 selectable depth ranges up to max. of 120 m with a connectible continuous alarm. The power supply is 12 V. A 150 kHz transducer and an installation bracket come included. A sensor with a 7 m coaxial cable, including a connector is also included with this unit. Current consumption is typically rated at 130mA. Dimensions of the bracket: 200 x 130 x 90 mm.

Also available as a twin version with an additional LCD display (no decimals displayed).

Our tips for the proper assembly of this unit:

First, you must provide voltage to the display device and connect it to the transmitter. Next, you must hold the transmitter in a water-filled plastic bag until a stable depth reading is achieved. Now, the final tuning of this device can be performed. However, if no stable depth reading can be successfully achieved, you should choose a breakthrough assembly instead.
