Hydrostatic dunk tank $50 - right price?

My gym charges $50 for a hydro dunk and skinfold to determine bodyfat...is this about the right price to have this done?

I paid 25. At the local college.

That seems alittle high but if that's the only place around u that does it then your stuck w/ paying the 50 bucks.
It's 25 bucks here also.
