The Wisdom 4 continues the tradition of the Sherwood Scuba Wisdom computer brand.  Now in its 4th edition, the Wisdom computer remains one of the bestselling Air Integrated Consoles in the industry.  With the easy to read large characters and simple layout the Wisdom is a fan favorite.  The most significant difference between the Wisdom 3 and 4 is Bluetooth integration to DiverLog+.  With the 4 there is no need for a connecting cable and your laptop or desktop.  Just a simple synch between your phone and the Wisdom 4, you can upload all your settings into the Wisdom 4 or download all your dives to the DiverLog+ App.
