I bought the pod because it was cheap and I wanted to see if I could “modify” it to accept the larger 3 in 1 gauge. For some reason they don’t sell a pod for the standard gauge with a larger option for the bigger 3 in 1. I used a round file and opened up the hole, the 3 in1 fits tightly in the pod now. Looks custom! So now I have a 2 gauge pod with 4 separate readings.
