A personal history of wrong purchases and what they taught me.
A personal history of wrong purchases and what they taught me. Over time I have become less interested in owning more equipment and more interested in understanding why a specific object deserves to be in the water with me.
The question behind the gear
After Open Water I once went to a large sporting-goods store and bought almost everything at once, before I understood what I actually needed. I bought yoke/INT regulators when DIN would soon make more sense for the diving I was moving toward.
I chose masks for looks, BCDs for features and products that seemed attractive in a shop but behaved differently after repeated real use. Those mistakes now help me explain to customers and students not only why I recommend something, but why another product may be wrong for them.
An error is useful when it changes the next decision.
The practical point
That is the thread running through this entire series: verify, simplify and keep changing your mind when better evidence or better experience gives you a reason.
The expensive value of getting it wrong
My first large buying spree happened immediately after Open Water. I went to Decathlon and bought almost everything while I still knew very little about how my diving would evolve. The clearest mistake was choosing INT/Yoke regulators rather than DIN for the direction I later took. I replaced equipment not because it was necessarily bad, but because I had bought before I understood the requirement.
The same learning happened with masks and BCDs. A mask that looked attractive became uncomfortable after instructor-level use. BCDs that seemed good in a shop did not give me the configuration I wanted underwater. Those mistakes are now useful when I talk to customers or students because I know that “good product” and “good product for this person” are different statements.
The decision comes before the object
The easiest way to accumulate bad equipment is to start with the product instead of the problem. My order is the opposite: what is the dive, what can realistically go wrong, what information or capability do I need, and only then what item earns a place on the configuration? That is why my equipment changes between a simple recreational shore dive, a teaching day, a sidemount wreck dive and a planned technical dive. The equipment is not my identity; it is a set of tools chosen for a mission.
This is also why I am suspicious of the idea that carrying more automatically means being safer. Every extra item has a cost in drag, snag potential, preparation, maintenance and attention. Redundancy matters, but good redundancy is deliberate. Two independent pressure indications can solve a specific failure. Three random accessories hanging from D-rings do not automatically solve anything.
Experience should make the system simpler
Many of my present choices came from earlier mistakes. I once bought almost a complete set of equipment immediately after Open Water and discovered very quickly that buying before understanding creates expensive lessons. I bought INT/Yoke regulators when DIN would have suited the direction my diving took. I chose masks because they looked good before learning how much fit changes after several dives a day. I bought BCDs that I later disliked. Those mistakes were not wasted money if I remember what they taught me.
After enough repetition, the interesting question becomes less “what can I add?” and more “what can I remove without losing a capability I genuinely need?” That is the principle behind my current sidemount rig, my lighting choices, the way I decide whether a compass or camera comes with me, and even the two plastic boxes I use to transport and rinse equipment.
Evidence, preference and honesty
I am comfortable saying that I love a piece of equipment. I am equally comfortable saying that part of the reason may be completely personal—lime green makes me happy. The important thing is not to turn preference into physics. When a technical claim matters, I want it checked against current manufacturer documentation, training material or good safety evidence. When it is simply my experience, I say so.
The same applies to instruction. I want divers to verify what they are taught rather than treating the instructor as an oracle. Procedures evolve. Equipment evolves. Evidence can overturn old habits. A good diver should be able to explain why a procedure exists and know when the answer comes from a manual, an incident analysis, a manufacturer limitation or personal preference.
A useful test before buying anything
I ask three questions: what problem am I solving, what new failure or maintenance burden does the solution introduce, and will I still want this item after the novelty has disappeared? If I cannot answer those questions, I probably need more dives or more research before I need a credit card. That test has saved me from repeating some of my earliest equipment mistakes.
