Unipro 7003 Laptimer

Hi, one of my friends bought an used kart. Mounted on this is an Unipro 7003 Laptimer. I tried to find out whats the difference to other Unipro Models but wasnt very succesfull. I just found out that it was the most expensive model of all Unipros Maybe you can help me out whats so special on it?

Most fancy laptimers have GPS, rpm, water temp.

Here’s a manual for the timer

Appears to have 8 connections available. You’d probably need extra stuff to use all of them. Typically with a mychron we’d run water temp, rpm, Egt, I think.

water, lap and speedsensor is already there

advantage with Mychron is the software available for analysis and seems like an easier unit to navigate in general.
