Hola, Mbchiro!! Saludos to all. Have been to Bonaire 3xs, stayed @ the Buddy Dive Resort and NEVER had a problem w/ any gear missing from our truck while diving or while on a break as in the restaurant. Usually when we are going for the shore dips, we take all of our tanks w/ us to avoid the driving back & forth. No one has ever messed w/ our gear. Just make sure you follow some basic rules: don’t carry any excess cash and what you carry, keep in a waterproof case, leave the truck windows down at the shore dive site, avoid flashing "stuff" around. This we did, given that my roomate and I are ex-soldiers, we posted someone as a quick lookout and then hid the truck keys and our loose cash at a marked spot near the truck (basic tactical fieldcraft, not part of the resort’s briefing) and, upon returning, kept an eye for any new arrivals @ the site, recovered our keys and continued w/ the diving mission. Safety is still numero uno! Never heard of tanks getting stolen as of yet on my trips. Not to say it won’t happen but, they are are serial numbered and they can easily be checked among the shops. A tank can easily be replaced, you can’t so I would not worry too much about it, just be aware of your surroundings and dive safe. Hope this helps a bit. Enjoy!
