Lange and Harpenden are the only two really good calipers out there. Forget the cheap plastic ones, they're junk.
As others have said, hydrostatic weighing is the best, but the right calipers in the right persons hands can be very close to underwater weighing.
Use the Lange's or Harpendesn's in conjunction with a Jackson/Pollock equation. Those can use anywhere from three sites to as many as thirteen different locations on the body.
If you were instructed properly on how to use the calipers you can become very accurate with them. In grad school my ex phys professor made us ALL do 1000+ of them in conjuction with under water weighing. We would have the undergrad students in at least once per week, along with anybody else we could drag to the lab. The students would be weighed under water. Without knowing the results, us (the grad students) would then use Lange calipers and a three site test to do another BF test on them. The lab supervisor or my professor would keep an eye on us. To get an "A" in that class, we had to do over 1000 tests and be within 1.5% of the hydrostatic test score at least 90% of the time. You either got an "A" or you got an "F", there was no other grade to get. You either got good, or you switched to a different major.
For me, this was 15 years ago and I still do at least 100 or more tests every month with my calipers. I'm pretty confident in the test results I could give you with a pair of Lange calipers.
