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

I owned one for about a week if that means anything to you.

The problem is too much variation in water clarity to make them work
properly.

Not worth the effort.

FYI, upon Googling quite a bit this afternoon, I did discover that a
"Clinefinder" is rated very very highly by anyone who owns one. It is a
device that very accurately reads temperatures. Quite simple, on a reel, a
cord, a weight, a sensor, and an aa battery. At the transition of a
thermocline, there is also a radical transition in oxygen levels, so just
finding a thermocline will put you in an oxygen level striation. The
troubles are two: they are $140 each, and only have 50' cables. People
rating them good was four out of five. Nonetheless, I do believe I will be
getting one for crappie fishing.

Owner reviews for ALL oxygen sensors related to fishing were very low, from
poor quality to big swings in readings. People rating them good were one
out of five.
