Tandem jumps are a very popular way to make your first jump. They allow the curious potential student to experience, first-hand, the thrills of skydiving without the stress of AFF or SL progression. Most dropzones are set up to offer tandem skydives under two different scenarios: the "one-time fun jump"", or as part of a hybrid training method sometimes called "tandem progression." The former only requires about 30 minutes of ground preparation; the latter is generally completed after a fairly standard First Jump Course (FJC) which can last up to four hours or more. Tandem jumping, by definition, consists of an experienced jumper called a "Tandem Master" or "Tandem Instructor" and the passenger. The tandem master rides on the back and wears an extra-large parachute system capable of carrying weights of up to 500 pounds; easily able to safely suspend two people. The passenger (or tandem progression student) wears a specially designed harness that attaches in four points to the front of the tandem master. A tandem freefall generally lasts between 45 and 60 seconds, followed by a four minute canopy ride to the ground. Tandem jumping provides an obvious advantage for the adventurous spirit who cannot adequately meet the physical or proficiency requirements for the S/L or AFF jumps. By relying on Tandem Master's skills, they will still be able to experience the thrill of skydiving. It should be noted that, in the United States, tandem jumping is conducted in two different modes: as a "ride" by manufacturer-rated Tandem Masters, and as bona fide skydiving instruction by USPA Tandem Instructors who also hold the manufacturers’ ratings. Only USPA-rated Tandem Instructors can teach tandem as a part of hybrid skydiving instruction. In most of these hybrid courses, a student makes three or four tandems and then finishes training starting with a level four AFF jump. The utility of this hybrid method is that there is never more than one instructor involved in any one skydive, thus freeing up staff to more quickly train the student load. Jumps made with a USPA-rated Tandem Instructor count towards student proficiency, those made with a non-USPA rated Tandem master do not. Tandem jumps range in cost from as low as $70 dollars (US) to over $300, so it’s best to shop around for the best deal.
