Purchased a descent t1 a little while ago everything seemed fine, covid hit and didnt dive for a while, 2021
start of 2022 started diving again
noticed there was a firmware update after changing the dead battery.
since then it has been OVERESTIMATING my actual bars remaining
when i empty the tank it still shows 27 bar even though it should read 0
checked with another SPG and its overestimating by ~ 27 bars.
numerous other people seem to have similar issues see

it seems to read incorrectly if the battery dies or possibly the new firmware update.
this needs to be rectified by Garmin, currently im awaiting a response from the garmin support australia. they have sent me a RMA link.
