On the latest software the powersave mode is on by default but can be disabled so that the displays dont automatically shut down.. I can't speak for the v2.5 hardware but all the 2.0x hardware uses a power hungry dispay (significantly higher than similiar displays) battery time will be reduced.. I have not opened up the handsets of 2.5 hardware but they VISUALLY look the same..

for example the typical current draw is 15ma on the 2.0x hardware without the backlight active.. for comparison the HH dispay is under 2ma..

I don't think anyone could argue the displays aren't power hungry. Rather than faff around giving people the option to have the displays on all the time, it would have made more sense just to upgrade the handsets. Still, changing the batteries is hardly a big deal, and if you check the voltage before splashing it's hardly a safety issue. I've adjusted my Meg to take 9v alkaline dry cells from any convenience store, so even if I'm tinkering with kit at midnight I can pop over to the cornershop and get a new stash of batteries. Ultimately, I neet to get 2x 9v cells in parallel, but I haven't got round to it. It would really help if ISC put together a battery module that helps people load generally available batteries without the need for soldering. The present situation where people are paying international freight for custom battery packs is plain silly.

I don't understand the comment about 'peace of mind' from having the handsets on all the time. I instincively hit the Confirm button as I pull the handset towards my face, thus waking it up. If you're doing that every couple of minutes through every dive it soon gets into muscle memory.
