What are the disadvantages of having transmitters on all your tanks?I agree that relying only on a transmitter is not a great idea. Weird stuff can happen with electronics, the battery might go bad and you don't have a spare or tools on hand to change it, etc.
SPGs, button or full size are only so accurate. Especially at the ends of the gauge.
I'd argue that in this day and age a transmitter is no more unreliable then any other piece of kit, and possibly more accurate the full pressure drop of a tank than an SPG
