I also wish that the Thump2 lenses were available for the Gascan. I wonder if you called in the order, they would do it for you?You can if you go to an O Store or Vault (but then you can't change the Icon)
Also the thump 2/ Gascan lenses ARE slightly different in geometry, but still fit,.. So a educated phone salesperson will probably advise against it, or refuse the request. BUT, Why not try. :)For a while it was advised against, but customers did not care so you should not get much argument about it anymore.
