From the specifications and after handling each unit it quickly becomes clear that there are big difference between the Pro-Find 15 or Pro-Find 20. The Pro-Find 20 allows you to turn on / off the audio and adds vibration indication. Unfortunately, neither the Pro-15 or Pro-Find 20 have a LED light or are they waterproof.
The real significant upgrades come with the Pro-Find 35 where in addition to having On, Off Audio indication, Vibration Indication – it also has a LED Flashlight, 5 Levels of Sensitivity and Target Identification Standard, 6 Ferrous Tone ID.
