The display panel shows the relative magnitude of conductance (reciprocal of resistance) between the two test probes when these are inserted in the soil. The tester measures the dryness or wetness through soil resistance readings (0 to about 5 kilo-ohms) and indicates in dot mode by sequential lighting of LED1 through LED8.

Great light for hard hat.
Style: 180 Lumens
These lights are perfect for our crew. They mount easily over a hard hat. Our guys are tough on them throwing them in the truck or down on the Jobsite. Very durable and offer good lighting for individual worker. Batteries will last a whole shift.

Great Helmet Light
Style: 250 Lumens
Fantastic illumination which is what I need when I’m walking under ground in train tracks area the tunnels aren’t very well lit. This gives me added lighting along with my flashlight to make me feel safe plus help me watch my step.

Good light. Minor flaws.
Style: 180 Lumens
Good light, only flaws is that it didn't come in a box. It was just in a clear plastic bag. And batteries were not included.

Puts out a lot of light!
Style: 220 Lumens
I had to have an explosion proof light, and this one puts out an amazing amount of light! On flood light ( second push of button) it lights up an amazing amount of area around you. The spotlight will hit a tree in my back yard while standing in the front yard. Very impressive!
