Thanks to its particularly ergonomic shape the HL 50-BT is a single hand operated instrument. Two operation buttons and a thumb - that‘s all you need to use the HL 50-BT.
In the standard version, the HL 50-BT offers an integrated sensor and wireless headphones. There are no irritating connection cables. The HL 50-BT therefore offers optimal mobility and is highly suitable for listening to valve spindles and hydrants, but also to fittings in buildings.
