by Edge Coastal Instruments

A calm coastal instrument.

A quiet pane of glass in a hand-built hardwood frame, showing what the coast is doing right now: weather, tides, sky, surf and the next ferry. Hand-built in New England.

No AI. Just quiet functionality.

The Salt Light Instrument Home screen: temperature, air quality, the day's tide curve and the next hours.
