The history of baton passes has been a bit mixed up and unclear. It sounds like the first may have been Potron & Chalon in France in '56 => This is correct : when the french did it in 1956, there was an article in some US magazine, the writter said what this act was a shame and he was hoping what this would never be repeated ! By the way, Jacques Chalom is still an active skydiver.

L.O.R 2 - is a good system - I worked with is a lot & saw it in action - I think the reason it never moved out of PdF rigs is the patent & the cosmetic issue & the use of very specific 1.5 mm double Cypres loop only from PdF BUT it was a "good" advanced improvment in case of one riser failure. Quote LOR 2 is the ONLY design which guarantees the reserve will not activate until the main has been totally released (not the case with a Collins lanyard associated with a left riser equipped with a three rings systems out of use). The 20 years patent is over now, but actually there is one other disadvantage on the LOR 2 beside the ones Shlomo wrote, you cannot accomodate a mard device with the LOR 2

About the sigma : this situation should never happen since you do not deal with a 3 rings release system and in peculiar his double end loop, so I do not think the sigma manual speak about it. the older atom tandem rigs had already tuck away risercovers, but the french method is made for all kind of tandems, not for one manufacturer product. my guess is if the Tandem Vector 2 manual is the only one to speak about it, it is probably because the entranglment of the disconneceted main risers with the reserve deployment did happen in the first tandem days..

sorry I made a mistake, I meant in France we teach a different solution, in this situation the tandem master has to cut away before pulling the reserve ripcord..which is not the same than the Vector sorry for the confusion

I have to add that in France we teach a different solution, in this situation , the tandem master has to pull the reserve without cutting away..

thanks for this reply, I have been thinking about this could be the reason, then I gave up because I could not imagine the risers rings going through the big ring , except if risers are loose enough and the risers cover weak..but I guess it is the reason..

in the Tandem Vector 2 Tandem manual (page 88), in case the tandem master pulls both first handle then the secondary drog release handle wand still the main does not release , the tandem master MUST pull the reserve ripcord. Question : do you have any idea why they do not ask the tandem master to cutaway first ? what is the inconvenient to cutaway ? I see only advantages => very often this malfunction is due to the double-ended loop so on the reserve opening chock, the main finally open, and since it is not free to leave ..it becomes an issue. What do you think ?
