Wow! I don’t have just one favorite piece of equipment. My entire gear set up is awesome to me. I wouldn’t want to dive with a substitute for any part of my gear set up.
BCD is the Scubapro Knighthawk. (Absolutely love it)ScubaPro MK25/600s Regulator (It’s a work horse and a easy breather)
Suunto Cobra II dive computer ( All I can say is it’s an excellent piece of hardware)
I didn’t know how valuable my mask was to me until I tested a low volume mask last May. Yikes!! I hated that mask, so I switched back to my former mask w/a better appreciation for it.
The only piece of equipment that I am not sure about are my fins. I’ve bought four different pair of fins and still can’t seem to find the pair that makes it happen for me.
I"m buying another pair next month to try out on my upcoming trip to Turks and Caicos.
Oh.....the warm water beanie...I never dive w/o it. Two dive knives and a pair of diving shears (dive in Northern California and Kelp you’ll understand)
Lastly...Dive Alert Plus...both water and air horn...let’s face it. I really like my gear!!
