FWIW
didn't want to go through the work and expense installing a new rear view mirror with temp, so picked up a minn kota water temp sensor with a 10 foot lead for 6 bucks on ebay. velcro to a thin walled 1 1/2 aluminum angle and velcro that under the dash so it lays over the shifter cowling. lead zip tied to grill. seems pretty accurate, probably too much so--sit at a light on a day like this and it responds quickly.

 

How long do the batteries last? Is it backlit?

Thanks.

 

no backlight, I have the ashtray light suspended just under my cb and it illuminates a bit. no idea on the battery life, it hasn't died yet, but it's only been in since first week in July.

 

Thanks!

I bought one on eBay last evening.

 

good luck with it, so far it appears to be extremely accurate.

 

I have something similar. Runs on one AAA. I think I've replaced the battery once in 4 years.

 

Got mine installed and seems very accurate as well. I mounted the sensor on the backside of my grill with 3M doubled sided mounting tape.
