Well, I can tell you the leakage has not been fixed. We bought two of the gemini's 5 months ago from LDS. One of them leaked out the mouthpiece on it's first dip in the pool. A simple adjustment and it was fine. We live in denver so these see a dip in the pool prior to each trip to make sure all is working well and then off to cozumel for a week of diving...this is done twice a year. Our first dive this week and mine was leaking. Jumped on Sherwood's website to look up dealers in cozumel and every 'dealer' listed on their site would tell me they don't sell Sherwood when I called. If Sherwood's website can't direct me to an actual dealer, how do I find one? Why would shops be listed on Sherwoods website who don't rep their gear?
In any event, I finally found someone in one of sherwoods listed shops who said he would adjust it though he doesn't recommend using the brand...simple adjustment like everyone says. The next dive...hers leaked. Another adjustment. Two dives later BOTH of them were freeflowing. Adjust, adjust...they worked again..for one dive. The good news is I am getting really good at oral inflating while performing a tight swim through...the bad news is I have to orally inflate while taking pictures or video or holding a flashlight etc. These Gemini's are making me crazy. Yes, it is a simple adjustment. Yes, I've considered bringing the tools down in my BC if I knew where in cozumel to buy tools and no I should not have to go through all of this for a piece of equipment that costs what these do.
An equipment failure for me is not the end of the world....when one fails on my female dive buddy though....it very easily could be. I don't mind orally inflating (ok, I do mind but I am willing), and not having any sort of backup air source...she absolutely does mind, (because she is the smarter of the two of us). I am very seriously considering throwing these in the trash when I return and going with Zeagle's version. I can't even bring myself to sell them on ebay knowing how they could be a danger. Going to give my dive shop one more shot at it. They have 12 dives on them and have been in the shop nearly half that many times. There is something very wrong with this design. Nothing should loosen up that quickly. It's the backup air source that is leaking so much...and I might have taken 6 breaths on mine in its lifetime, while she has certainly taken half that many. Why is it loosening up when it's not even used?
There is nothing more frustrating than paying a bunch of money for something and having it constantly fail while nearly new. Perhaps I am being harsh on Sherwood, but then this is two identical units failing one after another repeatedly...that's not a random problem.
