Re: [drenaline] What are your thoughts about the sorcerer.
In reply to:
Its the Base rig with reserve, do you think its useful or not and why?
I state in advance (I never jumped a Sorcerer but I have Sorcerer packing video and I have seen Sorcerer's and know a friend who jumps Sorcerer (but this chap only jumps terminal walls...)) that I think that Sorcerer is a state of the art BASE rig, incredibly well thought and incredibly well designed and manufactured. But Sorcerer is a very complicated piece of BASE equipment indeed. By very complicated I mean: it is not easy to assemble properly, it is not easy to pack a canopy into it (consider that into a Sorcerer you have 5 layers of canopy while on a single-parachute rig you have only 3 layers, so the parachute into a Sorcerer is way more "squeezed" than into a single-parachute rig)) and finally it is not easy at all made your mind up to its proper use: if you DO have a reserve, you MUST be mentally prepared to "do-what-in-case-of-what-malfunction": not easy indeed.
Said the above, I try to explain why 95% of worldwide BASE jumpers use single-parachute systems for BASE jumping.
And, by the way, as "BASE jump", do you mean "low" BASE jump of "high" BASE jump?
Let us consider for the moment "low" BASE jump (for "low" being BASE jumps off objects in the 300ft-91m ÷ 500ft-152m range). Well, in such jumps, considering jumping a Sorcerer, it is very unlikely that in case of a total malfunction: 1) you realize you are having a total and 2) you deploy the reserve and 3) you deploy the reserve in a manner you can walk away with it.
Let us consider now "high" BASE jump (for "high" being BASE jumps off objects in the +1150ft-350m (or so) range). In such jumps, considering jumping a Sorcerer, consider that you can: 1) deploy your (main) parachute quite high above ground in order that in case of malfunction: 1.1: total: you can deploy directly your reserve; 1.2: partial: you can cutaway and deploy the reserve (that deploys quite fast(=in short altitude)) and ride safely to landing: in this case, jumping a Sorcerer is a very good idea; 2) deploy your (main) parachute so close to ground to re-enter into the category of "low" BASE jumps, and so, see above (=uselessness of having a reserve on your back...).
Now, what type of BASE jumps do you do regularly? Only terminal walls? Then possibly the Sorcerer is the BASE rig for you (provided that you are very WELL trained indeed: to assemble it; to use it; to pack it and to know very well indeed ALL its possible uses and do's and dont's)
Do you jump regularly at the same percentage both low objects and terminal walls? Maybe more low objects than terminal walls? With a Sorcerer you CAN jump also low objects (in my country, a brass ones jumper jumped a 246 ft - 75 m building with a Sorcerer (but that was the only systems he owned at the time...), but I don't see why jumping a double parachute system in those cases (and could be the 90% of your jumps) in which having a reserve is completely useless (no time/altitude to deploy the reserve) and only add complexity to the system.
Consider also, in real cases and in real BASE world scenarios, that, even if the Sorcerer's reserve opens in very short altitude/time, in case of partial malfunctionings (=line twists, for example) it not so "easy" to cutaway and deploy the reserve, if you consider that you are quite close to the wall, you are spinning under your main, you quickly cutaway deploying automatically the reserve (it is so the the dual parachute system works and this is why it opens in such a short altitude/time): guess what? Your reserve opens in a line twist fashion (it is obvious: your main is spinning, the "attached-to-the-risers" reserve free bag leaves the container still spinning... you got the point?) and so you are left with the original problem (=being VERY close to a wall with a spinning parachute).
On the other hand, a single-parachute BASE rig, yes, has ONLY ONE parachute, but it is WAY simpler, it is WAY simpler to assemble it, to operate it, to be mentally trained to use it (= no need to cutaway, do not even think about it!!!), to pack the canopy. The parachute is WAY cleaner packed into a single-parachute BASE rig (only 3 layer of cloth compared to the 5 layers of a Sorcerer). Furthermore, single-parachute BASE rigs have a very good reputation for working properly (even if this year there has been one case of a total with a single-parachute BASE rig, quite unexplainable, but unlucky events can happen even if you use all your possible care...) and so very few BASE jumpers feel the need of having a reserve on their backs.
I am not an expert neither an authority but I hope to have explained why only 5% (or so...) of worldwide BASE jumpers uses a Sorcerer BASE rig.
In fact, I belong to the 95% (or so...) of BASE jumpers who use a single-parachute BASE rig.
In BASE, simplicity is the key word. If it's simple, it's hard to confuse or misroute or misdo.
