Temp/Oxyegen sensors

[Paul S]

Has anyone had any experience using the temperature / oxygen sensors that are sold as a combination unit for around $50.00 ? I'm wondering how accurate they are.
Thanks

There was one for a buck on hsolist the other day in the fishing area, I'm not sure it's what you're looking for or asking about, but it was there.
