Sharing dive computer

Question: Can you take 2 computers and swap the transmitter? I know some transmitters will broadcast to multiple computers, and if only one of you is diving each day, taking the reg set with the transmitter is easy enough. You would be accurately tracking your NDLs even.

His wife has a non-air-integrated AquaLung computer, and he has an ai-integrated Suunto. The AquaLung cannot read the Suunto output, even if the AquaLung were air-integrated. She needs an SPG, or needs to use his computer for its gas readout.

The thing with travelling around is that less weight means more flexibility. Want to grab a motorcycle and tour a bit for a few days? No problem because we’ll only bring two bags. Go for a hike? Why not, we didn’t bring a stroller but a baby carrier. That extra 100grams will make a big difference when hiking up a mountain or going for a jungle trek. It’s the total sum of everything. And yes, renting all our gear would save a lot of weight

For example I only brought a 40L backpack with me last year while we traveled for a month through Borneo. Less than 10kg in total. Ah well you get the picture. We like to be adventurous and diving matches that perfectly. If anybody needs tips on how to travel light hit me up

Best of luck to you! Your lifestyle appeals to the minimalist in me .

Number one rule of any dive class is DO NOT SHARE DIVE COMPUTORS!
That being said each diver breathes differently and that equals different nitrogen saturation in the body.

When alternating diving days, each of you'll have ~36 hrs breaks between the last dive of the day and the next morning dive, so every morning the diver starts with a negligible residual nitrogen. Just reset the computer and dive.

While that is generally good advice, it doesn't have anything to do with this thread.

The OP was not talking about sharing 1 dive computer between two divers on the same dive. That is a bad idea, but unfortunately, many divers do that.

What the OP was talking about was sharing 1 dive computer among 2 divers who are alternating dive days. The only one going on all the dives would be the dive computer. Most likely the nitrogen loading will be sufficiently reset overnight. Worst case, the computer will think the diver has slightly higher N2 loading because the computer did not get the 24 hour break that the diver did.

While that might be true, the computer has no way of knowing about it.
