Product Information
The Halcyon Weighted Single Tank Adapter (STA) is a marine-grade stainless steel mounting platform that bolts between a single cylinder and a backplate, adding 3.42 kg / 7.55 lb of ballast so the diver can skip separate weight pockets. It includes two tank straps and a plastic-coated 2.35 kg / 5.2 lb weight that lifts out when less ballast is needed.
Who it is for
This is for the single-cylinder diver running a Halcyon backplate and wing who wants ballast carried on the centerline instead of on a belt or in pockets. Because the ballast is carried on the centerline, it helps hold horizontal trim and keeps the harness clear of bulky pouches. Divers who travel can pull the removable weight before packing and run the adapter in its lighter configuration.

- Total weight: 3.42 kg / 7.55 lb
- Removable weight: 2.35 kg / 5.2 lb, plastic coated
- Material: marine-grade stainless steel channel with bolts
- Two tank straps included for securing the cylinder
- Engineered for a balanced center of gravity and a streamlined profile
Compatibility and sizing
The adapter is designed to work with Halcyon backplates and Halcyon wings for single-tank diving. The same removable plastic-coated weight is also offered as part of Halcyon BC configurations, so the ballast carries across those systems. The product page carries a California Prop 65 warning.

Frequently Asked Questions
How much weight does the Halcyon Weighted STA add to my rig?
It adds 3.42 kg / 7.55 lb in total. Of that, 2.35 kg / 5.2 lb comes from a plastic-coated removable weight, so the adapter runs lighter when that insert is taken out. Because the ballast sits on the centerline, the STA eliminates the need for additional weight pockets.
Can the weight be removed for travel?
Yes. The 2.35 kg / 5.2 lb weight is plastic coated and designed to be removed easily, so you can pull it before packing or whenever you need less ballast. The stainless steel channel and bolts stay in place and continue to serve as the single-tank mounting platform with the two included tank straps.
Does it come with tank straps?
Yes. The package includes the weighted single-tank adapter unit and two tank straps. The straps secure the cylinder to the stainless steel channel, and the channel bolts to the backplate. No additional weight pockets are required because the ballast is built into the adapter.
What backplates and wings does this STA work with?
It is designed to work with Halcyon backplates and Halcyon wings in a single-tank configuration. The same removable plastic-coated weight is also offered as part of Halcyon BC systems. If you are pairing it with a specific plate, wing or cylinder size, contact DiveCatalog.com and we will confirm the setup with you.
