## Questions & Answers

**Q: Does this thermometer float**
A: Yes it floats. However, i found that the string rotted /then snapped during a single summer season. Then the internal mechanism must have rusted/corroded during the winter - even though i dried it out in the sun before storing away for the winter as when i wanted to return the thermometer to the pool the following year it would not read the temperature correctly. A minor side issue is that the 'chrome/steel' bezel around the dial rusted. Maybe because i have a salt water pool - but there was nothing on the product description that warned against it!
It was a shame as ergonomically i loved the design.
I now have a simple plastic floating duck thermometer.
Incidentally i have a couple of other (electronic) TFA products which i have zero issue with both from a design perspective as well as reliability - so very happy with those.
