D9tx -- how many tissues does it calculate?

[Meni Meller]

Hello,

I own a D9tx for quite some time, and other than the bolted pin that holds the titanium strap to the body keeps getting lose and lost... the computer works ok.

I read that suunto's RGBM uses a 9 tissues model, the new fused rgbm uses 15 (like most modern dive computers).

Didn't find any information regarding the Technical RGBM, does it also use the 9 tissues model ?

PS, the bolt connecting my titanium strap to the dive computer got lose and lost, how can I get a replacement or two ?

Thanks,
Meni,
