I have a Sherwood Wisdom 2 computer with quick disconnect and compass. It is Sherwood's best computer. This computer normally runs for about $800. I'm asking $450 firm. If you are interested, please email me at mike@digit16.com if you are interested or you can PM me here. It is new and has only been in the water ONE time to try it in the pool. It still has the plastic tear off protector on the screen.
