Sorry, premature posting.
I second reducing the data to 2 stats per page and increasing font size. Color is not important to me. Vibra-alerts would be great. How hard would adding voice alerts be. If it vibrated then told you what the notification was for it would take the guessing out of it, trying to remember what each sound was for.
I also second the uselessness of a wrist mounted pulse oximeter. As a paramedic, professional pulse oximeters attached to heart monitors are finicky enough. I'd have no confidence in any watch or phone that claims accuracy.
Bluetooth would be nice, but keeping the cost down would be a higher priority for me. I also don't need the gps.
Congrats on the impressive prototype. I have no idea how one builds such a device, much less in that short of time.
@ggalinsky Just curious, what/how are you doing depth sensing? And also, have you take into account the differenent density of salt vs fresh water - it can make a difference depth reading.
Units of measure has always been a bug bear. It’s either metric or imperial for everything. I live the rest of the modern world operate on metric so like temp in degrees celcius but am an old salt and like depth in feet. I have no idea how far 10m is but 30ft I’m all over it.
having the ability to select what unit of measure applies to each unit Would be good.

By default I think I'll display in metric, but also include a mode called "freedom units" that measures the depth in inchesThat's easy. If you multiply meters by 3.3 you get feet.
So... how many fingers is thatThat's easy. If you multiply meters by 3.3 you get feet.
Hi,
if you are just testing depth, why don’t you do it in the lab. if you can build a watch, I’m sure you can sort out a pressure tester. You probably rig up something to press that buttons under pressure too. Don’t need to worry about weather, boats vis etc. Or send a couple to people on here for testing

If you tested it and the readings are decent it could be a nice optional extra in my opinion.
A forehead sensor sounds more usable to me. It could incorporate a silicone skirt that would minimally interfere with the mask, stick to the skin well and sit under the hood in a place that sees the least movement for accuracy. I think this would be very insightful information to have for dives.
