    Thanks. I understand the concept and always thought that, but I've heard differently from others. I can also understand what they're saying since a small percentage of decompression is done between 70 and 20 feet (I use 50% rather than 32%).

    12 min difference on this particular dive.

    2hr 15min or 2hr 30 min, both suck in the lake

    The biggest problem with this dive on OC is that they don't make doubles that big.

    Thanks. That's what I thought. The only real advantage is savings on helium. What RMV did you use? That seems like a lot of gas for that dive. I have decided to go with a SCR so deco will be OC, but I'll be able to spend a lot more time where I want to. And I can use it with my SM rig. Two SCRs on order.

    Bill, I've had longer deco than that. My MP3 player keeps me entertained.

    Our family has scheduled a memorial service for Tim on August 20th in Milesburg
    Pennsylvania. Details can be found at the link below as well as a place to put your condolences.

    Book of Memories for Timothy Borger at Dean K. Wetzler Funeral Home

    Thanks to everyone that has helped us through these tough times. A special thank you to all of the divers who have spent their time trying to find Tim.

    The Sheriff's office brought specially trained dogs out earlier this summer to help identify where Tim's body is. They identified an area near the old dam that has helped the M.C.S.O. in their search. Hopefully soon we will find him.

    As of now their is no memorial scheduled in the Phoenix area. If things change I will post on the boards. There has been some talk of a party in Tim's honor but it has not come to fruition yet.
