It arrived today, on time ,paper instructions well there are non. that said I fumbled through the three buttons on top. it took about ten minutes to some what weave my way through the set up mode. now I am a semi expert .Plugged in the charge cable to my USB computer port ,using a Dork USB tester.The Seek Thermal charged at a .7amp rate at 4.99 Volts It took about 1 hour to go from 0% to 100% charge. The flash light about 300 to 400 Lu. bright better than expected. its screen is 1 3/8 wide by 1 7/8 IN. high. you can take still pictures but no video .Then later down load to your computer .on the seek you can change the color of what is hot or cold real good feature. The picture quality is low def. that is standard on all makes .The price of $244.63 Made this a must have. I must stress don't think any of these type of units produce high definition ,not even close!! In menu scroll to ABOUT they show your model # serial # and there web address at thermal.com/revealsupport you can view and or down load complete instructions ,and more after you register. by HERB THE POWERMAN

Compared to similarly priced devices, this one has a much larger thermal sensor and display resolution. This device is super useful for home owners, travelers, or spies. It can be used to look for trespassers/animals in the dark. It can also be used to quickly look for anything that might be overheating in case a fire alarm is going off with no obvious cause. Another good use is looking for spy devices/hidden cameras while travelling. Any running electronics will give off heat. You can also see which security cameras are dummies and which are real if you have a need to know that sort of thing. It can also let you know if someone recently was driving a car, walking barefoot through an area, opened a door, or which keys they pressed.

The RevealPro is an incredibly powerful tool but it has a bit of a learning curve to understand the different filters and modes for each use case. One pitfall is the normal and full frame mode will scale based on the lowest and highest heat items it sees, so if you have a popsicle or flame in the field of view it completely messes up the scale (unless you use the span and center mode where you can set your own scale of 60-100f etc. etc. It doesn't have the fancy image contrast overlay that some of the competitors have but it doesn't really need it since the thermal sensor has such great resolution (for a thermal imager). If you are patient and learn the settings you can see all sorts of things, such as footprints where someone just walked barefoot or studs and areas of weak insulation in walls. I used it already to diagnose a failed car window defroster.

The only downsides are that the UI is a little clunky and the field of view is narrow but you get used to those things.

This thing is awesome, especially for the price. It can detect temperature differences of slightly less than 1 degree F, so heat leaks or missing insulation is easy to spot. You can see if a vehicle has been driven or an electrical outlet has powered a high-load device like a coffeemaker recently. Powered electrical or electronic devices are also easy to spot--even low-power devices like an inactive cell phone charger stand out. You can see handprints on walls and drops of warm water on the ground for a few minutes--the exact time depends on the size and temperature and wind. It is a true thermal imager; it doesn't need any any ambient visible light at all to work.

Build quality is good; I wouldn't expect it to survive being run over by a tank, use as a hammer, or repeated drops onto concrete, but you don't need to handle it with kid gloves, either, The display has a clear plastic panel over it, and the lenses, USB port, and card slot are all recessed enough to give them a reasonable amount of protection. I would say it is about like a decent-quality cell phone--handle it with a reasonable degree of care and it will last for years, but I wouldn't expect it to handle much abuse. I don't believe it's waterproof

The manual isn't much, but you don't really need it. The menus are simple and clearly labeled, and the screen labels the current function of the buttons. The only thing that isn't clearly labeled is powering on and off--you hold the center button down for about 2 seconds to do that.

The unit will capture still images, but not video--the frame rate is only about 5Hz. I'm sure this is one of the compromises necessary to reach the price point. Capture is simple, just press the right button and the current screen image is saved to the memory card.

Accessing captured images is easy; just connect the unit to a computer with a standard USB cable, and the micro SD card will show up as a removeable external drive.

The flashlight is activated via a dedicated button on the right side of the unit. The button toggles between high power, low power, and off. You can adjust the high and low power settings in the menu. The imager does not need to be on for the flashlight to work. The beam is aimed the same as the thermal imager, so you can see what the thermal is looking at. This helps identify the source of a heat signature when the thermal view alone is not clear. The beam is slightly wider and more diffused than most flashlights, but not so much as to make it useless. If you want to light something up 100 yards away, you should probably use a standalone light, but for nearby things, it works well.

The device is light and compact, and could easily be carried all day.

A few minor annoyances:
By default, all images captured are watermarked with the "Seek Thermal" logo. You have to go into the menu to disable the watermark.

Captured images are overlaid with the same square crosshair shown on the screen, and the temperature in the square. The overlay is always white, so if you are measuring heat sources you cannot see the crosshair or temp reading if the color scheme you've selected displays heat as white. You can't change the crosshair overlay design or color. Fortunately, there are several color schemes to choose from, one of which is a negative B&W that shows heat as black and cold as white.

The battery cannot be removed/replaced without disassembling the device. But the internal battery is sufficient to run it for several hours, especially if you have the screen brightness turned down. You can also connect an external battery to the USB port, and use the device while recharging it.

The unit has an automatic shutoff that prevents battery depletion if you forget to turn it off. But if you aren't periodically pressing buttons while using it, it will shut off without warning. If you plan on using it longer than the auto-shutoff time, take a picture once in a while--any button press will reset the timer. The default setting is 15 minutes, but you can change it in the menu.

The unit comes with a carrying strap, USB charger, and a USB cable, but no carrying pouch. A Condor I Pouch (Black, 5 x 3 x 1.5-Inch) is just about perfectly sized, and it has an extra compartment you could use for a cable and charger or spare battery. And you can configure the MOLLE loop on the back as a simple belt loop or attach the pouch to a backpack or tactical vest.

Overall, great value and performance for the price. It has a variety of uses, and could pay for itself just with it's ability to identify heat leaks. 4.5 stars, rounded up to 5.

I was very surprised with the performanc of this unit. I have use much mor expensive units but nothing of this quality for this small of a price. Almot 2 months after purchasing this unit, we had an external fire at the house that had started to get up into the house rafters when I discovered it. Since we live out in the country, calling the fire dept was not an option to save the house. I grabbed a garden hose and started putting it out myself. When I thought I had it put out I remembered the thermal imager
I used it to survey the damage and even found some unseen hot spots in the rafters that I hosed dawn a bit more. I have no doubt that this unit saved our house. Best purchase I have ever made!!
