Here is a link to ScubaPro's warranty:

I can't find any info in their warranty that would indicate what you are expressing.
What the ScubaPro warranty does say is:
"To obtain warranty service, you must deliver the affected component or part, together with your proof of purchase to any authorized SCUBAPRO dealer."
and
"No salesperson, dealer or representative is authorized to make any modifications to this warranty or to make additional warranties on behalf of SCUBAPRO."
If what you state is true then that is a great reason to NOT buy ScubaPro products.
When I had an issue with my Aqualung Drysuit I contacted AL and they gave me the option of working through a shop or sending it directly to them. I wound up working through the shop I bought it from but according to my discussion with AL I could have taken it to any AL shop.
But I do understand your point...a bunch of years ago my wife and I were in the market for a new car. We had just moved to Belgium and were originally planned to be here for 3 years. We are Subaru fans and faced the issue of there being very few Subaru dealers in the region of Belgium we live in coupled with the fact that buying a European spec car would present issues with importation into the US due to different safety standards. When we looked into buying and shipping a Subaru over from the US we found that Subaru of America does not have a reciprocal agreement with Subaru Europe for warranty issues/service. We wound up not buying a Subaru.
