Rated 3 out of 5 by from Not great with 64 series The unit works and displays nicely on the 64s. I hear good things from people with the Oregon but on my 64s it's only average. The Tempe must be synced as if it were new each time the 64 is powered on again. The ANT will show searching but never find the unit until you turn the ANT off and then turn it back on again. It's not that big of a deal but it's annoying. Keep the Tempe away from your body and the sun. Just like the instructions say, it will mess up your readings. No knock against the Tempe for that. It's just a reminder.

Rated 5 out of 5 by from Fantastic Accessory This Tempe is a great addition to your Garmin compatible GPS. I am using the Tempe on my Garmin Montana 600. Nice to know what the current temperature is or how cold it got during the night. Sometimes I even use it at home with the sensor outside in the shade outside to read the current temperature or to see how cold it got. It also records min/max temps even with the gps power off so you don't run the gps battery down by having to leave it on all the time. Of course you just need to keep the sensor out of direct sunlight and away from any heat source ( your body included ) to get very accurate temp readings. It is very hard for me to tell how much gps battery drain comes from the added wireless communication between the sensor and gps but that can also be turned off in the setup menu if you want. I love this wireless temp sensor and thank REI for carring this product.

Rated 4 out of 5 by from Fun GPS Accessory This is a great toy/tool and I use it whenever I pull out my GPS. However, I am always afraid that it will fall off and be lost whenever I clip it on my pack as designed. Would be great if Garmin would add some sort of tie point as a backup.

Rated 3 out of 5 by from Not accurate when exposed to direct sunlight This is a great idea in theory, but it doesn't quite live up to expectations. I believe a lot of it has to do with the fact that Garmin chose to color the sensor black. If you are anywhere in direct sunlight, the temperature will spike many degrees above ambient. Recently took a hike on the AT from Hogpen Gap to Flatrock Gap and in the early morning clouds it worked great attached to my shoe. However, when the sun came out I had spikes up to 96 degrees! Did a short hike on the AT approach trail this past weekend and decided to try wearing it under my lightweight and thin gaiters. No effect, there were still wild temperature variations. I'm going to hold onto it for a while longer to try out other mounting positions, but I think anywhere that gets direct sunlight is going to be bad. Will also try it hiking or walking under overcast skies to see if performs better.

Rated 4 out of 5 by from Good ANT+ Sensor But With Hiccups Bought this here at REI last April and have paired it with my Oregion 450 (after upgrading the Oregon's software to recognize ANT+ sensors). It paired smoothly and the Oregon started receiving temperature readings. What's cool is that now for every tracks I record the temperature data is included once I upload it to online apps. What I don't like is that there have been a few times wherein the temperature reading does not display on the Oregon either after booting up or midway through a tracked activity. Not sure if the one doing the hiccup is the Oregon or this Tempe, but the result is still the same: Not getting the data. Already happened about 4 times and it's come to a point wherein I don't care if the temp is going to be included in my tracking data or not. There's no way to tinker with this product as there's nothing to it like buttons or what-not. Also, this sensor is finicky when it comes to spitting out data, for it's going to be affected by the location where it's placed and if it's directly exposed to sunlight. In order for it to give out realistic data it should be placed in a shade or anywhere that it's not exposed to sunlight. There's also an after-market product (available here at REI) which is a sleeve where this sensor can be inserted and it claims it protects the sensor from sunlight or rain which allows it to perform normally. If this is something that you think would help satisfy your data cravings go for it. But if you don't care what's the temperature around you every second, then spend your money on something else worthwhile.

Rated 3 out of 5 by from Challenged by Sunlight and Body Heat This sensor is accurate in a stable environment, i.e., indoors, total shade, neutral placement conditions. However, further research and development could advance the effectiveness of this tool. In my house, it reflects an accurate temperature, same as thermostat. Take it hiking, and that changes dramatically. On its first trip on a local desert trail, I moved it to a number of different locations, including boot laces, pack zip pocket, waist loop belt, and finally under the top edge of my pack on the carrying handle which was also shaded by a hat with a neck flap to provide additional shade. I checked the actual outdoor temperature on my cell phone. The sensor was anywhere from nine to four degrees off the actual temperature. It will be awhile before we have cloudy, overcast days again in the desert, and it will be interesting to see if the absence of sunlight will result in more accurate readings. I would suggest to begin with that Garmin make the housing "white" and also design it for air to pass through the housing. I am contemplating returning this item.

Rated 4 out of 5 by from Great little gadget One of those great little gadgets that not real useful but fun to have. Nice to be able to see what the temp is outside while your still snug in your bag. Makes it easier to decide if you want to get up and freeze or catch a few more zzzs while it warms up outside :)

Is this compatible with my Garmin Etrex H gps personal navigator? Or how about my Samsung S4 mobile phone?

Asked by: Mark and April
The only eTrex model that is compatible with the tempe would be the eTrex 30. It is not compatible with older eTrex models. The tempe will only work with select GPS units and watches. It will not sync with the Garmin Connect app on a smartphone.

What is the field of range for this product? I have a fenix 2 and would be using this to monitor inside vehicle temperature when transporting dogs. Thanks!

Asked by: CrisW
The Tempe must be within 9.8 feet of the Fenix2 to get a reading.
