Marathon Replacement Remote Outdoor Sensor - Monitors Indoor & Outdoor Temperature in Celsius or Fahrenheit - Compatible with Model 27-FD Atomic Clock

The remote sensor that came with the unit went crazy reporting negative temperatures when it was 50 degrees. This reasonably priced replacement arrived quickly and is working great. Very happy it was available when I needed it.

Could not get it to link with any of my weather clocks

This product looked promising to replace the existing Radio Shack 433 Mhz outside temperature transmitter. I put the batteries in it, and it started displaying the temperature. However neither of my two weather receivers (one made by Radio Shack and the other by Oregon Scientific) could pick up the signal. I tried resetting all devices repeatedly, but this device apparently transmits on a different channel that the other devices simply cannot pick up. Both existing 433 Mhz devices used to be able to capture the transmitted signal from the old device until it stopped working. Maybe it will work with other devices, but it was a disappointment for me.

I lost my remote sensor in a move and got a quote from Marathon for $40. It was a real pleasure seeing and purchasing this for less than half that. And it works great.

with the clock you get outside temp. and it's easy to pair.

I could not like it, it did not work

Oh, my mistake. My thermosensor I'd wanted to replace had multiple channels, in addition to the transmitter frequency and this unit is not being translated by my base indoor atomic clock. My own fault. Sorry.

Work very well
