Are there plans to develop a simplified and cost effective way to save bathy data from the DFF3D? The system works great with the TZT3. I wish I could save the information. I have looked at the Nobeltec software. Seems like a throwback to 2000 to buy the basic software and then two additional modules to save data. And the retail price is basically the same as the DFF3D and the transducer. Makes no sense
