Well.... this should be a sign for the industry and how our economy is operating.
Dive Tank was a decent sized shop that was well known, especially for AL/Sunnto products and drysuit sales.
For them to go out of business just shows the stress that the rest of the dive industry is under. When things like gas prices limit your every day expenses and limit your dive trips, it's also going to limit dive equipment sales.
I don't think theres a dive shop out there, on Scubaboard or other, that would deny that they are seeing an economic downturn at their cash register.
Maybe so but we don't really know what caused the demise of divetank. Maybe sales were down and it wasn't generating enough revenue for the owner. Maybe there were supplier problems and either they couldn't get supply or lost favorable pricing levels. Maybe they lost their credit card gateway because of chargebacks. Maybe the owner just found something better to do.
