2 Parter - re: DS 125

Here's my 2-part question:

Part 1)
On my last dive trip I noticed on the glass lens of one of my DS-125's what appeared to be scratches or maybe little cracks... somewhat foolishly, I didn't think much of it and continued to dive through the trip with no issues. I'm about to leave on another trip and now I'm wondering if I should have the unit sent in for servicing (can the glass be swapped out? Is this recommended if the glass is only scratched?). For what its worth, the unit is operating fine.

Part 2)
Assuming I send in my DS-125 mentioned above, does it make sense (and is it even possible) to use a DS-125 along with a DS-50 as a second strobe? For the record, I'm shooting using an Ikelite housing for my Nikon D-80 dslr.

Thanks in advance,

Josh

Part 1: The front lens can be replaced. If it as cracks, It would be caused by a chemical reaction from using products like Salt-X. If the lens is scratched, they fill in with water and do not effect anything.
Part 2: No problem mixing types of DS strobes. You will be limited by the recycle time of the DS-50.

Probably a dumb question, but is using a DS-125 that is scratched (or even has tiny cracks) NOT recommended?

Using one that is simply scratched is no problem. Using plastic that is cracked underwater is a serious problem! If you're unsure I would send it in... Otherwise a very simple repair could turn into a fairly costly one.
