The sealed battery makes me wonder how well the battery will hold up after a year or two of regular diving though. Owners of smartphones with sealed batteries will probably have experienced the difference between a new phone's battery life vs after a year or two of use.
Would be good to hear back from owners of this computer after a period of regular use to see if the battery still lasts an entire diving day
When not in diving mode, the battery is able to hold for 3 months out of water, therefore if one go diving average once a month, you might not be able to test how good/bad it will be after few years. this is unlike phones, we charge it almost every day, that translate to 365 charges per year. As for this dive com, you only charge it on your diving days, so how many diving days one do in a year for leisure divers? Even for people who are in diving business, how many diving days one do in a year?
I am not selling this dive com, just share my opinion here.
