This is a variation on a theme, but I was looking at a few threads in the New Diver section and questions regarding gear. Then I began thinking about all of the gear I bought when I started diving then realized it was either not necessary or need to be replaced. Of all the money I could have saved off the bat.
I did go straight to a back inflate BC so did not have to replace a jacket style BC.
Lost my dive knife on my first dive. After that I no longer buy expensive titanium dive knives, I buy cheapest steel knife I can find under $20 and closer to $10. Very high likelihood of surrendering to King Neptune at some point, would prefer to donate something cheap.
Snorkel, need I say more? $65 waste of money.
Split fins, well ... actually happy with mine but after all the post on split fin haters thinking maybe should invest in blade fin as well. (maybe free dive fins if ever get a chance demo them with Dan Volker)
Dive lights, I'm now changing all my xenon/halogen bulb lights to LED lights. Added benefit is I can also use the LED's topside as flashlight. It's amazing how well they work at my barbecue at night !!
I almost bought a console dive computer. I'm so glad I didn't because now I want a wrist mounted air integrated computer. You don't really know what you want or need for your style of diving until you've had a few dives or been exposed to other dive gear.
So, for all of you veteran and newbies alike, any advice for others on what to skip or buy to avoid the cost of having to replace later?
