Stable ultra-light sensor with the unique pfa quick-release tensioning system. With a handle, the probe can be absolutely safely stretched and just as quickly collapsed again and put together. The probe is tensioned with a Dyneema draw line. This is not only lightweight but also durable. For the 240 Carbon pfa, we use a tube diameter of 10 mm. The carbon probe is extremely rigid and therefore very accurate. The grip sleeve made of EVA foam allows comfortable handling during probing practices. The burial depth can be read from the markings on the segments. The 240 Carbon pfa is delivered with a handy quick-release cover.
