Hi, I am looking for advice on purchasing a new (first) dive computer. I have only used the Sherwood insight, so I don't have much comparison, but I was looking into the Sherwood Wisdom 2. Does anyone have advice on purchasing one, I have located some online, but there appears to be two different "Wisdom 2" models, which only clouds the issue. One option is the dive shop where I was originaly certified is selling a Sherwood Brut (not 2010) regulator package and Wisdom 2 dive computer with compass for $650.00. Seeing this is the older version of the Brut and and a used computer is this a decent price? Any advice would be greatly appreciated! Thanks
