Can anyone point out any differences between the Oceanic Pro Plus 2 and Sherwood Wisdom 2? (besides style/how they look) Their features look identical to me, and I've been reading the instruction manuals for both of them and those are almost identical too. (There are whole paragraphs that are word-for-word identical between them, their table of contents and organization are exactly the same, and the warning messages are also identical) Are they both made by the same manufacturer? Also, I notice that they both use exactly the same software for downloading data (except for the logos).
