RS3 log issue

Hi, i have tried to download my log history from some survey work yesterday, but it seems it has been split into 1 file per 1second?? I have no idea why it has done this (and seems to be OK again today). I really need these logs to be able to pair with some sonar data, but it is near impossible to download 1000 individual logs. Any ideas? I only need the LLH files. Screenshot of some of the logs.

Which firmware version is your Reach RS3 on? Can you please also share a full system report of your receiver? To keep it private, you can send it to We’ll check what may cause this behaviour.
