Good old Hilma is one of the deepest dives (for non technical divers) in Bonaire. Access from the shore requires 5-6 minutes of swimming toward the buoys first. Some divers prefer to submerge at the shallows and dive the drop off. This is fine too but I'd rather conserve all my air for the wreck. Start your descent from the northern buoy, explore the length of the wreck, then take the slope up to the shore. The deepest end of the wreck is at about 100 ft which may be at the safety edge of higher Nitrox mixes. Keep an eye on your gauges. The wreck is safe for EAN32 through which is the standard Nitrox mix at the island.
