Amazon.com Review
Many modern homes have up-to-date clocks or mini weather stations that depend on radio-transmitted data to stay calibrated and current. The La Crosse TX3UP works outdoors by sensing temperature and transmitting that information to an indoor station. It transmits to a base up to 80 feet away. The TX3UP can be added to augment information fed into La Crosse units already in operation. Plus, the 10-foot probe cord helps monitor soil or water temperatures.

Remove batteries from base units first and activate sensors; next replace batteries in base units and press no buttons until a display appears. The TX3UP can be used as one of multiple sensors; many La Crosse weather stations allow numbers to be assigned so that it's clear which displayed information is from which sensor. The TX3UP operates on two AAA batteries. Its housing is made of durable, neutral-tone plastic. The sensor works with all La Crosse weather clocks and stations except the Professional Weather Center Series: WS-2010, WS-2210, WS-2310, WS-2315, WS-2510, and WS-7015. For options in wall mounting, two screws and screw anchors and a strong adhesive tape are included. The TX3UP measures 3 by 2-1/4 by 1 inch. La Crosse provides a one-year limited warranty on its sensors. Each sensor comes with a detailed instruction sheet. --Garland Withers

Customer Reviews

First one sent back
The first one of these I received was showing incorrect readings from the sensor. I put it in my hottub to monitor the temperature from inside the house, but it was reading around 119F when I know the tub was at about 105F. I sent it back and Amazon replaced it very quickly. They even paid for the return shipping. The second one seems to be accurate so far. It's really great to be able to view my hottub temperature without going out on to the deck and opening the cover. It's cold where I live and I don't want to waste the heat just to find out it's not ready to soak. I turn it down to around 75F when I'm not using it. It takes about 2 hrs. to get to 105F, which is the temp I like to soak in. This sensor helps me know when it's time. Amazon makes buying off the internet easy and safe.

Can't do without it...
This is a great device for checking your swimming pool or hot tub temperatures without having to go outside. Range is excellent, accuracy is good, battery life is very good, and the price was tolerable.
Since I have two different remote sensors and one receiver, changing the batteries in the device makes you go through set-up procedures that are equivalent to standing on your head, spinning around three times, and clicking your heels; but thankfully the batteries last a long time and this isn't that big of an issue.
***Follow-up on 1/7/08: Although these are fairly accurate and trouble free; they only last about 2 years before failing. I have now ordered my third one of these within the last 5-6 years. The display will give you the letters, "OFL", and the unit fails to operate any more. LaCrosse Technology will not return phone calls or emails regarding technical support questions. Since these things are still kind-of cheap (they go up $1 every couple of years, and I just paid $20 for this one), it is still a decent investment.

Good overall, wiring a little flimsy
I bought this sensor along with the WS-9013U from LaCrosse (see that review). I use it to monitor the temperature on my hot tub, I get both the display inside on the weather station (which is awesome) and the LCD display outside at the tub itself. Note, the LCD is not backlit at all, so it's unreadable in the evening. I've had it installed for about 6 months now on the same battery and haven't had to change it yet. It seems fairly accurate and matches the temp. settings on the tub.

My one minor gripe is that the wire the sensor is on is fairly low-gauge and flimsy. I wound several wraps of electrical tape around mine where the filter lid rubs against it. Overall quite satisfied.
