The lightweight WTX D40 Wing from Apeks designed for Public Safety divers is now paired with the amazing and comfortable WTX Harness. This creates a great buoyancy system that is travel friendly and perfect for tech divers, or rec divers looking for something more modular than most BCDs.
The WTX Harness can be mounted directly to the D40 PSD but if you want to stiffen it up or increase the weight your rig can take you can also fit a stainless steel or aluminium backplate.
This bundle can also be paired with the WTX Surelock Weight System.
The WTX D40 is designed for use with a single cylinder and offers 40lbs of lift

Returns Information
If you change your mind, it doesn’t fit, or you become inflicted with buyer’s regret - that's OK!
Mike's Dive Store offer an extended returns policy of 30 days - so you can be rest assured if the suit, piece of diving equipment or gift doesn't suit then just send it back, and we will either exchange it or offer a full refund less any postage costs. Too easy!
Please note that there are some special order items on our website that will be subject to a 20% re-stocking fee, but we will let you know about these items before we special order them so that you are aware of this. If this is the case we can always help with correct sizing so that we minimise the risk of return.
