The letter (A reply to an inquiry I made) and their web site seem pretty clear to me. Key lines:
Al, you should do check-outs in Maui, I'd love to join you.
SCUBAPRO UWATEC USA does not authorize sales via the internet nor via mail order.
Although some of our dealers advertise our equipment, once again they are not authorized to make direct sales through the internet, but rather, authorized dealers are only authorized to sell SCUBAPRO UWATEC USA equipment over the counter at their retail location.
If you so choose to purchase SCUBAPRO UWATEC products online, the warranty will be voided.
awap:I do see the disconnect between this letter and related statements on the SP website. The source of my (our) confusion is fairly clear. I'm not sure what the source of SP's confusion is. If I have time, I will contact them about the ST sale and see what they say.
