I have got a humidity meter, but I wasn't really looking at it. It wasn't
that high. It was on the tow out, but for the dives I wasn't really
steamed up or anything inside. However, it could be something like
that. Maybe I will do a dry dive and test it.<u></u><u></u></span></font></p>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size:12pt">Hi James,<br />
I am no specialist but when I searched for meters for Pilot Fish, I<br />
was told that<br />
these type of meters based on electrochemical cells are not be rated<br />
for near 100% humidity, since they can misidentify water vapor or<br />
droplets as CO2 (CO I don t know but could be similar effect)<br />
Did you record humidity level?<br />
<br />
