Probably the most versatile module from Simarine, it's got the four 25-amp shunts to measure chargers and loads, as well as the inputs to measure tanks, temperatures, and battery voltages. You can also set up an alarm for *anything* the Pico is measuring, and have it set off the SCQ25T's relay to turn on warning lights, pumps, whatever is needed. One additional benefit of the Simarine modules is that there are several voltage-based and resistance-based inputs, so it will take whatever type of sensor you're needing to plug in. A very cool little module to expand the Simarine Pico's abilities even further.

 

I have been very pleased with all of Simarines products. Easy to install, user friendly, and so far reliable.
