In our free area on Youtube you have access to explanatory videos, device tests, presentations of our new products and much more. This content is freely accessible to all and updated regularly.

Our echosounders receive the following free of charge:

• Two-hour practical echosounder training with your acquired sonar on the Salzgitter lake

• Expert and support hotline for TFA echo sounder customers

• SIGNAL instead of WhatsApp support during opening hours (we love privacy)

As soon as you have bought an echosounder from us, please do not hesitate to contact us for an appointment (April to October) for echosound training on our Salzgitter lake.
