There are several regular posters who seem like they may have an arrangement with the brand they support. I'm all for disclosing these arrangements. I would like to hope this notice is enough to prompt such disclosure. If not, more draconian measures may be needed.
so, one of the big things that impacts this discussion is something that wasn't at least mentioned in the first 14 pages that I read, and I'll try to read the rest tomorrow *temporarily in the UK for work so way ahead of everyone else*. The industry in general has a roughly 3 year turnover. Very few people last longer than that, especially in the technical side. On the recreational side, if you last more than that, you are either a strictly tourist diver who is unlikely to be an active poster on here, or likely to be affiliated with a dive shop. If the latter, then you are going to have gear biases based on what you have experienced and what the shop sells. This will typically be one shop/manufacturer. Perfect example of this is
@Lake Hickory Scuba where Bryan is a Mares dealer and he fully discloses that and is quite open about why most of his gear is Mares. Key man discounts are the norm at this level and nothing secret in the industry
On the other side, you have the technical divers that are typically not associated with any individual dive shop or manufacturer. By this time, it is highly likely that relationships have been developed with certain shops and manufacturers just because of how few people there really are. Part of this means that no one essentially pays full price for gear, either through key man discounts, or "friends and family" type discounts, very rarely does anyone in this group actually get financial kick backs and if they do, you'll know pretty quickly.
@Deep Six is a somewhat unique exception as they are trying to change the industry model, but I think they've done a decent job of making the information on the affiliate program open
I have three links in my signature. UWLD, Cave Adventurers, and Deep Sea Supply. I am not, nor have I ever been on any of their payrolls, but make it absolutely no secret that I have bias towards their products/services vs. other manufacturers and I have no issue answering questions on why because they are products I believe in. I truly believe that UWLD makes the best lights on the market, believe that Cave Adventurers offers some of the best resources for sidemount diving in the world, and that
@cool_hardware52 truly changed my ability to safely and comfortably dive backmount on top of making some brilliant gear for reasonable prices.
Other companies like XS Scuba, Shearwater, Poseidon, Hollis, Deep6, HOG, and I know there are others but can't think of them are in a list of manufacturers that I am able to receive discounted gear and/or have received free gear/swag for different reasons. Every dive buddy that I regularly dive with has their own list of different manufacturers that we are able to avoid paying retail price with most manufacturers when we need/want something. If you have been in technical diving for over 5 years and don't have the ability to do that, then you are probably living under a rock or just haven't asked.
