How did we proceed with the fishfinder test?

After we were provided with the Fishfinder models, we inspected them all in sequence and made notes about the condition and feel of each echo sounder.

After that we went over to the practical test. We tested them one after the other on our boat at Lake Constance. In the meantime we kept taking notes. These were then included in the evaluation.

And now have fun with our product reports.

The displayLowrance Fishfinder Mark-5x Pro, grey is one of the few echosounders that feels really good to the touch. Even after we switched it on, we have to say that it keeps its promises.

The menu navigation is completely in German. The operation is also very intuitive and explains itself all by itself. If you want, you can of course also download the instructions on the Internet. But we did not need them.

The display is very detailed and shows you exactly the information you need. What is also very nice is that this fishfinder has an illuminated display. This means that the echo sounder can also be used at night.

Also very positive is that the display is completely anti-reflective. This means that you can see everything very well and in detail even in direct sunlight on the boat.

100m portable sonar sensor fishfinder fishfinder alarm beam sensor

The display100m portable sonar sensor fishfinder is a very affordable fishfinder. But not necessarily worse. It has a depth range of 0.7 to 100m and is therefore completely sufficient for many lakes.

The round transducer sensor is connected with a 7m long cable. This can be placed comfortably at any place. It also displays precisely the depth, bottom condition and fish including depth. Complete shoals of fish can also be displayed.

In our opinion a really good device at an incredible price.

Following the graphical evaluation:

navico Lowrance Mark-5x DSI Fishfinder

Note: It is possible that the item is currently not available. Alternatively, you can use the following display fishfinders.

The navico Lowrance Mark-5x DSI Fishfinder is the most expensive fishfinder in our test series. However, it has by far the most functions and really plays in the absolute top league in terms of quality.

With this echosounder you get pictures from up to 61m water depth. As you can see on the picture, these recordings are really very detailed. So detailed that you can even see the leaves of the herb and the underwater plants.

Also very nice is that you can go up to 80 km/h with the boat and still recognize something. The optimal image quality is obtained at speeds of 13 km/h. Here the picture on the display is really pin sharp.

The Down Scan technology with 800kHz in the Lowrance Mark-5x DSI Fishfinder display delivers the right pictures in black and white.

The handling takes some getting used to. But after experimenting a little bit with it, one gets used to the handling very quickly. The price is the highest in our test series, but compared to the pictures that are possible with it, it is quite cheap.

If you often use a fishfinder, the navico Lowrance Mark-5x DSI Fishfinder is the right choice.

Lowrance Elite-3x Fishfinder with transom transducer 83/200 kHz

Following a picture from the fishfinder test:

  • Colour sounder
  • Broadband Sounder
  • Water temperature sensor
  • Fish I.D.
  • LED colour display
  • z 83 or 200 kHz Broadband Sounder
  • Battery and charger not included


The disadvantage of this echo sounder is that no battery and battery charger were supplied.  You have to order both separately. This is in any case very unfortunate, because it means additional costs.

But in terms of functionality and equipment, this sounder makes a really good overall impression. If you still have some money left for a battery and a charger, you can strike without any problems.

Otherwise you might want to take another look at the Lowrance fishfinder Mark-5x Pro. Here the problem does not exist.

Electronic-Star Echolot Echolot Sonar-Fishfinder Fishing

The Electronic-Star Echolot Echolot Sonar Fishing display does what it should. In our fishfinder test it is the second most expensive and lies with it in the middle 2-digit range. In principle it shows everything it should. It can also be used on rivers, ponds and lakes.

The display is kept relatively simple, but keeps what it promises. Because of the display lighting this echo sounder can also be used at night. Even if it starts to dawn in the evening, this function is very helpful.

For the price, it is astonishingly suitable for deep sounding. It can be used at depths of up to 100m.
