I am on my 3rd year with Jaltest and really like using their Agriculture and on Off-Highway vehicle software. Their online repair information is one of my favourite things about the software.
JOEL RESENDIZ from J&H TRUCK AND TRAILER REPAIR – Illinois, US.
We have all types of trucks, heavy equipment and industrial machinery. The Jaltest software gives me a wide variety of access to troubleshoot problems in all types of equipment in our industry. That saves us valuable downtime and faster turnaround on repairs.
Anthony Percacciolo, Head Mechanic at DANELLA CONSTRUCTION – New York, US.
I purchased this unit specifically to diagnose my Mack trucks, but I have taken advantage of the ease of access to ABS, wiring diagrams, and emission control issues, to name a few, on my trucks fleet wide. It is literally everything I am looking for in medium/heavy duty diagnostic software under one roof.
Mat Stephens, Director of Maintenance from TH Ryan Cartage. “Satisfied customer of a fleet running over 275 power units”. – Illinois, US.
Jaltest is a very logical software in my opinion, so no prior training is needed for basic fault finding. I highly recommend this tool for any yacht that requires maximum efficiency or one that operates in less travelled routes.
Ben Vos from Mia Elise 2 – Florida, US.
We use the Jaltest Marine Diagnostics on a daily basis in MAN, Volvo Penta, MTU and CAT with excellent results. We recommend this software for service technicians and engineers in the marine industry.

Compared to competitors’ products, Jaltest stands out as the only one that covers pretty much all functions needed all in one package. The depth of diagnosing, calibrating and providing necessary schematics and repair information is just astounding.
