Am I right in thinking that there's no way of knowing the battery level of the transmitter until it's connected to a tank?

And even then there is nothing that tells you the transmitter's battery status until it tells you to replace it. See manual "PerdixAI_Operating_Instructions_RevA" Section 8.1. Warning and error displays on page 18.

Oh that's sh*t!

Just replace it after a year or 150 hours. If you use fresh batteries you should never see the warning.

I noticed a considerable difference last year between the life of the battery in the transmitter and the life of the AA in the unit. Then I realized that I had used my regs a lot more than I had used my computer since a large number of dives had been pool training dives. Thus my transmitter was always on since there was pressure being put to it. I don't use that set of regs as often for pool sessions any longer.

Another approach to the transmitter battery issue is to have a new battery available (plus or minus O ring), so when you get the low battery warning you can change out at next convenient time. The lithium cells have a long shelf life.

I've tried searching the board but have not read through 72 pages of this thread...I'm hoping someone might know the answer to this.

I'm thinking of getting a Perdix but am still interested in keeping a backup computer. I don't have the funds to get a second Perdix or Petrel but my thinking was a less expensive dive computer that was either the same algorithm or more liberal than the Perdix. (It would be silly to have a more liberal primary and a conservative backup for fear of being locked out or upsetting my backup which would defeat the purpose of a backup.) Do you have any suggestions? I'm not familiar with the different algorithms in as much detail as I know the rest of you gear junkies are.

I did find this which is super helpful but I don't know enough to decipher or know which is more liberal and conservative outside of Suunto's RGBM. Dive Computer Algorithms I've tried Googling some comparison charts or graphs. Is Oceanic a good option? What do you suggest?

Thanks SO much!

You, sir, are brilliant...twice in one day! Thanks. If you were to pick a backup that is more liberal than the Perdix, would you go with the Oceanic out of all the options?
