The Zeagle Rear Weight System 16lb has top and bottom access for easy loading and unloading and has a 16 pound capacity (8 pounds per side). The unique feature of the Zeagle Rear Weight System 16lb compared to the longstanding rear weight system 20lb is the ability to position these pockets on either the top tank band or bottom tank band easily. Many divers are adding additional weights to the upper portion of their dive systems for better diving trim, these pockets allow you the option to position your trim weights on your Zeagle BC at either tank band level. Some divers will want to install 2 sets for this purpose. The new Zeagle Rear Weight System 16lb will function quite well with as little as one or two pounds or up to 8 pounds per side for excellent versatility.
