Trying to chose between these two units. I know the kids will love it for summer clear water fishing. But here on pools 7 and 8. Which one would be better for the hard water season. The 620 has a .05 lux camera and the 625 has a .01 lux camera. I THINK the .01 is better for the stained water or darker conditions. Is this correct?
Thanks in advance!
