Hi
@mullannix930
I can see how the Seac Screen price would be attractive. One concern you may have is the decompression algorithm. Though it runs Buhlmann ZH-L16C. it utilizes 6 presets without a custom GF setting. I'm assuming the Screen runs identically to the Seac Action. If that is true, the highest GF high available is 85, considered middle of the road/moderate, roughly similar to Pelagic Pressure Systems PZ+. I had posted this information once before, based on information sent to me from Seac
Seac Action
As this information is not contained in the user's manual, you may want to confirm this information with Seac if it is an important consideration for you
The Shearwater Peregrine has 3 Buhlmann presets and custom GF. It offers a color screen. Neither has a compass. Peregrine is rechargeable, Screen has user replaceable battery. Peregrine uses Bluetooth, Screen has a USB cable (purchased separately). The Shearwater offers considerable additional dive information that some of us have learned to appreciate, such as SurfGF.
Best of luck in your computer purchase.
