Can i send computer to mares directly?

[Dougmonkey]

Hi, my mares nemo wide computer flooded on a freshwater dive about a month ago, I immediately took the battery out and drained it. I recently put a new battery in and to my amazement it all seems to be working just fine!

Now obviously it needs looking at by mares before going in the water again, so my question is, can I send it directly to mares? Or do I have to take it into a dealer who's going to slap a load of extra cost on top?

I'm in the UK, near Norwich.
