Well since apparently the entire list is required to contribute to this thread I would mention that with the bt on your wrist you can observe your depth and control your buoyancy easier, especially when running a dry suit and a bc. Probably even more important with a double wing or a scooter, or a bunch of stages. Remember four feet too fast and you may get to learn the meaning of words like atalectisis (man i hope i spelled that right)and tension pneumothorax.. As far as only having one source of depth info, are these folks suggesting that they would lose the buddy,have the bt die and they would continue deeper? once you have deployed your knotted ascent line you have a reference right? and of course your anchor line is marked in some way right? And even in zero vis you can feel your going deeper in your ears right? I dont see a real problem with a spare in your pocket, but if you have a watch, bt,compass and light cord on your arms, how much room do you have left? throw in a knife and a wrist slate, well im only five nine, so im running out of room. Anyway thats my dime, I am outa here......... al marvelli Scaleworks@ao*.co* wrote: > In a message dated 99-05-20 14:46:13 EDT, mbloedorn@ya*.co* writes: > > << The point that is being made is not can you invent a > situation where maybe you can find a need for a piece > of equipment.
