My acurite pool hawk reads 158 degrees regardless of the themperature.

My National Geographic Weather Station is the opposite. The outside sensor only indicates the temperature, but the single CR2023 battery lasts a year. The inside unit on my desk lasts around 5 - 6 months and lets me know if needs a battery by showing the outside temperature as ' -- '

Although the manual says 'rechargeable batteries are not recommended', I would try 4 Sanyo Eneloop batteries. Or you could contact Acurite Support and ask them if your battery use is excessive?

That is most likely the sensor, call the maker of the device and try and buy the sensor.

We would recommend a reset of your Weather Station. Please verify that you are using a good-quality, standard alkaline battery, and follow the steps below.

1. Remove the batteries from the outdoor sensor only.
2. In the outdoor section on the main unit, there will be a "CH" and number 1-3.
3. If on CH 1, press and hold the channel button on the back of the unit for 5 seconds.
4. Press and release the channel button one time, it should show CH 2.
   • If it does not change to CH 2, repeat steps 4 and 5.
5. Press and hold the channel button for 5 seconds.
6. Press and release the channel button one time, it should show CH 3.
   • If it does not change to CH 3, repeat steps 6 and 7.
7. Press and hold the channel button for 5 seconds.
8. Press and release the channel button one time, it should return to CH 1.
   • If it does not change to CH 1, repeat steps 8 and 9.
   ***Regardless of what channel you begin on, clear out each channel by holding the channel button and return to CH 1***
9. Reinstall batteries in the outdoor sensor.
10. Press and release the TX button.
11. Leave both units side by side for up to 30 minutes to gain a strong connection.

Temperature Thermistor is bad

"A sauna is a small room or house designed as a place to experience dry or wet heat sessions, or an establishment with one or more of these and auxiliary facilities.
A sauna session can be a social affair in which the participants disrobe and sit or recline in temperatures typically between 70 degrees C (158 degrees F) and 100 degrees C (212 degrees F). This induces relaxation and promotes sweating.
Saunas can be divided into two basic styles: conventional saunas that warm the air or infrared saunas that warm objects. Infrared saunas may use various materials in their heating area such as charcoal, active carbon fibers, and other materials."

This indicates the the 2 installed temp sensors are having a reading the is more than 2 degrees in difference. It is either a failed sensor, or one of the sensors is not fit snuggly into the header.
To test a sensor, turn your multimeter on OHMS or RESISTANCE and connect probes to each wire. at 80 degrees, the sensor should read 93 OHMS. At 70 degrees it should read 118 OHMS
at 60 degrees it should read 153 OHMS

change the assembly valve

Firstly, though the answer is expressed as an angle "south" of west, the canoe will be traveling southeast, so the degree should be read south of east, not south of west. The ultimate velocity of the canoe will me 1.065 m/s.  The direction is 22 degrees south of east, or 158 degrees from West, but not 158 degrees south of west, since beyond 90 degrees south of west you have south. I used trig and I passed calculus so I'm pretty sure i'm right.
