I 100% agree and you raised two good points: underwater RF pollution and skills. I'm curious about that Brick (with new Suunto dc, It's the second brick of the week, we could open a contest...) from two point of view: As a nerd and computer tech I'm curious how they transmit all these information in a reliable way and useful range. As Linus pointed out, wireless communication could be problematic underwater (and he was speaking about a small distance: head - wrist). They state 70 devices connected, maybe it's just a theoretical limit but it's huge. I'm not a scientist or a TC engineer: which RF band should they use to have a reliable connection of maybe 20 meters underwater? Couldn't be dangerous for marine mammals (among the others)? As a diver, this is a complete BS to me but I understand that it could appeal to many (as usually BS do :) ). I imagine this could be useful for divemasters and instructors bringing in water people at their first underwater experience. For other scenario this is just a substitute for proper skills. Maybe I'm harsh but if I need someone who remotely checks my dive parameters or, on the contrary, I have to check my buddy dive parameters, it's better I stay at home. for mine and my dive buddy safety. This is anerd attempt to fill a lack of skills. I trust 100% my dive buddy otherwise he/she wouldn't be my dive buddy. So we are anal retentive with predive checks and undewater controls. nevertheless we need to communicate dive parameters one or maybe two times in a whole dive.
