Does anyone have or use one of these? I have yet to find a good O2

but did find a good product called Clinefinder for temperature sensing,
which the reviews tout highly. But the O2 sensors don't rate high, and

with a 50 or 100 foot cord seems to be spendy, although I haven't found
one
yet.

I will say this - outside of lab quality dissolved oxygen sensors,
they ain't worth crap to be honest.

They work on the same principle as the thnigy they put on your finger
in the hospital.

I was asking because I have yet to find one associated with fishing that had
any positive user reviews. The best thing was Clinefinder, which will find
a thermocline real fast, and there seems to be a big O2 differential right
at that level. It reads temperature, and not O2. Review of oxygen sensors
on a long string were that they were poorly constructed (one had the battery
door glued shut), or didn't work well at all.
