The fact is that the area of maximum stability is very simply illustrated in the Quadropod brochure and the difference in the area of maximum stability between a three legged tripod and a 4 legged Quadropod, assuming equal length legs, is compared side by side. If you like I can mail you the brochure or you can download it from the Novoflex web site. However Novoflex does not have their English site up yet so one of the brochures is only in German. http://www.novoflex.com/de/produkte/...d-broschueren/
We do have that one in English that we can mail. The second brochure on the web site is bilingual so you should have no problem understanding it but it does not illustrate the support area added by the 4th leg. The one we can mail or the one only in German does illustrate that aspect of the Quadropod.
