Please wake up guys.
There are two typical threats/tactics that LDS keeps using.
1. How can you be confident on your gear from the INTERNET? It is a life supporting equipment.
How much do you know about your LDS? Your LDS is more knowledgeable than any INTERNET vendors, such as ST or Dive Sports? It is all same. Your LDS doesn't manufacture an equipment and their customer service is way more slower and poor than most INTERNET vendors.
2. Where can you get tank filled?
I have told that there is a growing number of personal fill station in the market. In addition, many dive locations are getting their own fill stations more and more. "Demand and Supply"
Even, in my area, there is the new shop that is only selling an air. This can be another model in the market, "Demand and Supply" In addition, it is getting more popular to share a personal air fill station among a local hard core tech divers.
I have argued these points above since 2005.
#1 threat is almost gone on the board. Check out the old threads, specially when ST started to jump into the INTERNET market. Many Many members (LDS owners, instructor, shop monkeys) were trolling ST with #1 reason, but they have been all gone and we can't see them anymore.
Now, it is time to beat #2 threat.
While you are whining, market keeps changing and you will see less & less customers who bring their air tanks to your shop.
Just my 2 bar
