Ice fishing is hard water.
Open water is soft water
Hardware is just that, hard and physical.
Software is flexible not really a physical thing, also made around hardware.
Shawn has an LX-7 he wants to mount in his boat to use in the summer time, or soft water time.
Not to be confused with a software update for the LX-7 that he originally bought for use on hard water.
The link is not for a LX-7, rather later model classes of the LX 1-3-5 that do not have a software update for hard or soft water fishing.
Clear as mud?
