I agree Suunto is a more conservative alogorithm.....but that’s not necessary a bad thing. I think Suunto is a solid brand for instrumentation.....if I was an alpineer I’d probably chose the same brand. Had a cobra for years and loved it. I do not good warm and fuzzies about Oceanic for any gear quality. D4 is a basic computer so wireless transmission not a issue. I think you’ll find a lot of divers on a budget diving a d4 for years...good for free diving too, not gaudy, solid product.
