Just spent a couple of hours out in a mates boat trying to get sonar logging data to use for mapping with the Insight Genesis. He has a HDI-7 Elite (pre-Chirp), model before mine. Removed chart card, inserted a new 16gb micro SD card, used menu option to Start Logging. No options given as to where you are saving it. Message came up after about 20 minutes saying " you have less than 10 minutes left for saving to your hard drive/whatever" So it cannot be saving direct to the card, relying on a small internal memory. Try to save to card, but the only place we can find that option is in Waypoints/routes/Trails. And it only appears to save the actual waypoint or trail you have selected at the time. We kept saving, but each time the .usr file was the same size, as if was not being added to. Does anyone know where you can access the logged sonar data, and for that matter, all your saved data? Did a save, and it was showing user data (.usr) as a 128kb file size. Surely he has more than that, he has about 6 months worth of track on there. The manual is fairly useless, IMO, written by someone who either a) didn't give a rats arse, or b) makes a lot of assumptions about users' pre-knowledge of their equipment. Nothing better available online either.

Any ideas?
