Invest equipment you can depend on
In general, SCUBA is an equipment intensive activity that involves a basic technical understanding and requires that the diver has equipment that is appropriate for the conditions they plan to be in. This doesn’t mean that you have to break the bank, but you don’t want to skimp either. The most common phrase that applies to buying a Life Support System is to “Get the best gear that you can reasonably afford.” This means that you won’t find yourself needing to replace gear that’s not that old.
