Hey Owen,
can you let me know as I will have the same issues at some point

Glad you liked the torch!
On a side note have heard different things about re-charging the proteus 3 battery.
The manual states that the battery should be left always attached to a power
source when you have a 1/2 week break between dives.
However I have heard that this actually kills the battery life time from a
couple of sources. Does anyone have experience with this and could advise?
Cheers,
Michele
