I have a 3.854 and my dad's got like a 3.812 or something anywho...tonight i was testing and strangely enough, my dads older version didn't alert to all the falses like my new one did and also was quicker to alerting to IO and even picked up random spirts of IO ka band that i assume my new V1 was filtering out...so should i take both on my roadtrip or one or what..im leaving in like 12 hours so any help is nice

The 3.854 is on the left and the 3.812 is on the right...A jeep commander BTW
