The LightMap is a unique approach to displaying weather in brief manner. Utilizing an ICAO airport code of your choice personalizes the LightMap perfectly.
Using it at my summer cottage to allow renters to see the weather easily!
It will not vonnect to a 5ghz signal. And unfortunately newer android phones do not allow you to switch to 2.4ghz.
I very much like the Lightmap Sea. We own a home on a bay off of the Pacific Ocean, so knowing (eg) the tides is important, and normal tide clocks do not work with Pacific tides.
The wind and wave information is not as useful, as it tends to report that info from the ocean side of the peninsula we're on, rather than our location. This is completely understandable, and I guessed it before I ordered the LightMap. They can only display the info that's available online. While there's a tide station nearby, there is no weather data available, so that's that (there is non-federal info, but I understand not wanting to wire those sources into a long-life monitor).
The display is information-rich, but not 100% intuitive. I will eventually learn what all the various symbols and colors mean. I'm thinking of making a shortcut card to place near the LightMap to help out, as the manual is many pages long. Additionally, the richness of the display makes it a bit garish for those less interested.
All in all, this is a device similar to one I've considered building myself (retired computer engineer). It packs a lot of info into a small amount of real estate, and I think does it effectively. I recommend it.
