## Questions & Answers

**Q: Can it be used suspended underwater, near the surface? Will it read accurately between 30 and 40F?**
A: Ours is suspended 5 feet under water.  We haven't tested the accuracy but it does seem to be accurate.  We have had it only since beginning of summer, so do not know about reading between 30 and 40.  We plan to pull up for winter.

**Q: Is the  cable between the lcd display and the probe flexible?   can the unit be paired with a smart phone app?**
A: It is a flexible coated cable from the Display/antenna unit to the stainless steel probe. To view data remotely via smartphone requires Ecowitt GW1000, GW1100, or other specific Ecowitt console with wifi connection.

**Q: How does the sensor cable attach to the display?  Can I get a cable longer than 10 ft. ?**
A: Sensor is wireless

**Q: will this work with any of the other ecowitt monitors like weather station?**
A: Yes with latest firmware
