Hi
@olemiss36
If you want a watch style computer, I would suggest the Oceanic Geo 4 over either the Suunto or Aqua Lung computers. The Suunto (RGBM) and the Aqua Lung (PZ+) run deco algorithms that are middle of the road/moderate in the spectrum from conservative to liberal. The Oceanic runs a more liberal algorithm, DSAT, in addition to PZ+. This would give you a wider range of choices to fit your diving. The Suunto and the Aqua Lung appear to go for about $500, the Oceanic is $100 less
Personally, I think the Peregrine is the best of these computers. For $450 you get a big color screen, infinite flexibility with the Buhlmann algorithm with 3 standard presets and custom GF, cool features like SurfGF and the tissue saturation graph, and Shearwater service.
