Again, a must have gadget to keep if you are into offroading. It's got tyre depth guage as well. You might wonder why do I need it when I got external TPMS. TPMS shows realtime tyrepressue when the sensors are attached. When you are offroading in wild, you need a quick gadget to tell tyre pressure when you're deflating the tyres. Though, you can also buy a cheaper Rs. 150 guage but to me, the readability is an issue. You can consider other guage too. This one's not a hard recommendation.
