I purchased a PC-110 and L&M Mako with Sunray Halogen Lights about 6 years ago. for the most part, I only shoot warm water locations which is 3 - 4 times a year (another issue). On my last trip, I noticed that the infrared controls of the lights from the handles no longer work. During the trip one of the batteries finally failed (it didn't get a lot usage, but it was 'old'). I suspect the other will not be far behind.
While I have been relatively happy with output, the limitations of the camera/housing (e.g. no controls for WB or Exposure) have created pockets of disappointment. Now I take responsibility for a large part of it (not researching enough), but I am trying to figure out whether its worth paying the ~$120/each for these proprietary batteries; something like $300 for the annual service or whether its time to upgrade to HD.
There is no upgrade path with this housing. I am thinking about upgrading the lighting to HIDs. I have been reading about the challenges with the HC-7.
I realize in writing this, its rather obtuse, but I am not sure where to go next...
Any thoughts would be appreciated.
