The Penetrologger PRO is one of our iconic Eijkelkamp products, reinvented in 2025 to meet the demands of present-day soil investigation professionals. We asked Dr. Stefan Hinck if he thinks that this new edition meets the high demands that we set for it.
Dr. Hinck has his own fieldwork company, Field-Expert GmbH, and works for the Faculty of Engineering and Computer Science at the University of Applied Sciences at Osnabrück. What are his experiences with our new Penetrologger PRO?
The design and weight have improved significantly.
“My first impression of the new Penetrologger was: wow, it looks great! The device is also significantly lighter, which makes it more comfortable to carry. I think the design and weight have improved significantly."
The new model of the penetrologger PRO looks stylish, but what matters to me is the functionality. A new feature that I really like is the touchscreen. Also, the connector for the soil moisture sensor is now placed on the bottom of the device rather that the side, which used to be very annoying. And, much easier than before, it’s now possible to charge the device via USB-C and also connect to the computer via this USB-C interface.
“We work with the Penetrologger PRO for the detection of soil compaction in fields and for questions in the agricultural technology industry. The data can help answer questions that farmers may have, such as ‘I’m noticing anomalies in the field, we’re seeing lower yields there, we can observe waterlogging, we can observe other anomalies.’
With the Penetrologger, we can essentially define the problem area for the farmer, so that they can specifically loosen that area.
