I don’t know what the actual depth of the wreck is that will be used for this certification, haven’t gotten that far into it yet, just looking at what gear I’ll need to get. So until that’s defined, I guess I’ll just have to hold off on getting that pony bottle. The 130 linear foot max requirement leaves a lot of options, could be a wreck 120 feet down and we’ll only penetrate 10 feet into it, or it could be a wreck 30 feet down and we can penetrate 100 feet into it ( as long as that 100 ft is in the sunlight zone). All I know is that there aren’t any wrecks in Arizona, so it will be on a trip somewhere else!
