The result is a lineup where even the entry-level computer runs the same Bühlmann ZHL-16C decompression engine with Gradient Factors as the trimix-capable flagship, and where the display quality that made the brand's reputation in 2009 shows up across every model in the range.\u003c\/p\u003e\n\n\u003cp\u003eThese are the Shearwater products that move fastest at DiveCatalog.com — the computers, transmitters, and accessories divers consistently choose, grouped by what they're actually for.
