I am very happy with the latest Jaltest Updates and the software overall. Lots of great information on here. The schematics alone save you time and money as it is almost impossible to have all this information right at your fingertips.

Our guys love the DCbright Dark Licht M30’s on our pavers very cool non-glare technology allows them to work without being blinded!  Also like the larger Dark Licht non-glare lights for our yard applications which we intend to implement

Gobys are a very impressive equipment light could not believe the weight of them compared to the crappy lights we are using that get busted off all the time.  Unreal quality we will use them on all our equipment from now on.
