If your location does not have the Fit3D scan they should have another step on the scale with similar attributes. Wherever you do your first weigh-in is where you will need to weigh in for the remaining weigh-ins just because for this to be fair we have to have all weigh-ins for each participant consistent or there could be unfair variation.
Is it possible to go to a location to get the Fit3D for my own purposes?
Yes absolutely. It may cut into their patient schedule so please just make sure you call the office in advance to let them know you would like to do a scan.
