NASA TARGET 2 Echo-Sounder (Instrument / Sensor)

Drop-in replacement for old Seafarer 501 sounder. Uses the same transducer as the seafarer and the display fits the cutout for the seafarer repeater display. Only thing to watch out for on NASA istruments is the seal between the two halves. On my old boat it gave in after 10+ years, letting water leak in to the instrument.

I had decided late and now time was running out. Nevertheless, everything has reached me on time and the echosounder works since then without any complaint. Thanks again for delivery and service. Exemplary !!!

by Friedhelm M.

Very good value for money (delivered with the probe) large display, clear in direct sunlight with a function allowing to deduce the draft of the boat. It does the job very well with very good precision which I checked with a hand probe. The flat is on the notice (English and German) quite difficult to understand. I have not managed to use the treschold function and the sounder is disturbed at the port (this function should resolve this problem).

Product details

NASA TARGET 2 echo sounder incl. sensor with a depth-measuring range of 0.8 m to 100 m, adjustable low and shallow water alarm and keel offset.

The large instrument display with background lighting makes it easy to read the measured depth from a great distance. Power consumption is 12 mA (22 mA with lighting). Dimensions of the instrument are 132 x 98 x 30 mm.

Hole spacings of the stud bolts:

Horizontal: 80 mm
Vertical: 73 mm

Delivery comes complete with sensor and 7 meter connection cable.

Tip for the connection to an alarm transmitter:
Red wire to positive, black wire to the green display line (alarm output).

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.

Target.... Target hit!

So far I've only been able to test it in the harbor, but it does what it's supposed to quite accurately. It's easy to read, even in direct sunlight. The price-performance ratio is very good.

I AM VERY SATISFIED WITH THE PRODUCT!

11/18/2025 Verified purchase in use on a Bénéteau - Oceanis 350

Quickly installed

I attached the transducer to the hull with silicone where the depth gauge was most stable.

Then I ran the cable through the boat and mounted the display. Easy installation, good readings.
