This is the TEK / Travel frame from Silent Diving for all versions of AP Diving's Inspiration / Evolution rebreather. It is absolutely, 100% brand new, never used in any way. I got it for a really good deal in March 2016 thru a dealer friend, but I decided I like my yellow Inspo case, and I'm gonna keep my unit original.
You can see it listed at Silent Diving's website for $549 + shipping.
Comes in original packaging, with original Silent Diving documentation. I'll even send a copy of the invoice from where I bought it.
