I have a Helix 7 and a Lakemaster chip on the way.  Since the Helix 7 only has one chip slot.  How do I record screenshots, etc.  Does it have internal memory that I can record on while on the water and then replace the Lakemaster chip with a blank microsd chip to save the info?  My old unit had two chip slots so I'm not quite sure how this will work.
Thanks,
Mike
