Shopping for BCD & dive regulators can put a complete vest beside a small inflator component, even though both relate to buoyancy equipment. The key decision is simple: do you need a BCD that you wear, or a 45-degree oral power inflator for a more narrowly defined task? The Cressi S104 and the BCD 45-Degree Oral Power Inflator are not interchangeable categories, so choose by role before comparing price.
Quick verdict
The Cressi S104 Buoyancy Compensator Device BCD Size S Black Scuba Diving Vest New is the clear choice when you need a complete BCD vest with a padded harness, rigid backpack, storage pockets, weight pockets, D-rings, and an inflator hose. The BCD 45-Degree Oral Power Inflator Scuba Diving Buoyancy Compensator Metal Button is the better fit when the purchase is specifically for an oral inflator component. Their listed prices are $140.35 apart, but the price difference matters only after you identify which type of equipment you need.

Where each product wins
Cressi S104 BCD
The Cressi wins the full-vest use case. Its product name identifies it as both a buoyancy compensator and scuba diving vest, while the padded harness, rigid backpack, pockets, D-rings, and inflator hose give it the scope of wearable buoyancy equipment. It is the more appropriate direction for someone shopping for a BCD rather than a discrete part.
45-Degree Oral Power Inflator
The inflator wins when the desired item is specifically a 45-degree oral power inflator. The metal-button detail makes the intended configuration more specific, and the $140.35 price spread versus the Cressi makes it the lower-priced route for that component-focused purchase. It should not be selected as a substitute for a complete vest.
Product notes
Cressi S104 Buoyancy Compensator Device BCD Size S Black Scuba Diving Vest New
For a shopper who needs an actual buoyancy compensator, this is the relevant choice: it is a Small black BCD/scuba diving vest with a padded harness, rigid backpack, storage and weight pockets, stainless-steel D-rings, and an inflator hose. Those details point to a vest-oriented purchase rather than an inflator component. The trade-off is age: it is described as vintage, a few surface cracks appear in the rubber near the shoulder hose, and routine inspection/service is recommended before diving. Small is the stated size, so fit is central to the decision. Choose the Cressi when a complete BCD and its harness/storage setup matter more than the $140.35 price gap.
BCD 45-Degree Oral Power Inflator Scuba Diving Buoyancy Compensator Metal Button
The 45-degree oral power inflator format makes this the focused choice when the needed item is a component for buoyancy equipment rather than a vest. Its metal buttons are part of the named configuration, giving shoppers a concrete reason to select it for that narrowly defined task. The limitation is scope: it is an inflator, not a complete BCD or scuba diving vest, so it cannot fill the same role as the Cressi. Choose it when the 45-degree oral design and metal-button detail align with the part you are seeking. Its $24.65 listed price also keeps the purchase far below the Cressi, without changing what kind of equipment it is.
Final choice by use case
- Choose the Cressi S104 if you need a complete buoyancy compensator vest and can work with the stated Small size and vintage condition.
- Choose the BCD 45-Degree Oral Power Inflator if you need the specific component named in its title, particularly the 45-degree oral format with metal buttons.
- Do not compare them as two versions of the same item: the Cressi is wearable BCD equipment, while the inflator is a discrete part. The listed price gap is meaningful only when both choices could serve the same job-and here, they serve different jobs.
