Astro Pneumatic Tool 7767 Digital LCD Wide Range Positive and Ground Circuit Tester - 3.5 - 60V

Circuit Tester work great.

Slightly fatter than the one sold by snapon, but its a third of the price, and has a bigger screen compared to the snapon one.

I only use it 5 times! The internal electronic components are short-circuited! Really disappointed!

Shorted out first time I used it

Best test light you can buy! It can be used in place of a multimeter for smaller type of work. I compared the reading with my Fluke 87V and it reads only -0.10V lower at 12.5V. The current drawn by this light is around 0.10A so it isnt great if want to apply any kind of load on the circuit youre testing. im thinking about adding a small bulb inside it to make it draw 1 amp or 2, hopefully without heating the board and display too much.

Works great and seems well built. The backlight is bright and clear.

it came broken. the lcd screen has black marks on it. it internal. the Liquid crystal screen is messed up inside.

Much better than 7764, easier to read, better ground cable, and reads grounds

I expected the light to be brighter. When i used it out side I kept having to rotate it to see it I had contact or current.

A lot cheaper than snap on and all in all. Seems like its the same thing. Works great and has a higher voltage rating havent broke it yet
