AFR wideband (Innovate) gauges

[dom14]

Hey guys,

Can you please advise me the difference between below wideband afr gauges and if there any difference between them or if one is better than the other, etc?

They have different model numbers attached to them, but I'm not sure what those numbers mean.
Last one is not Innovate but a different brand.
My vehicle is an RB30 Patrol, carby, LPG/petrol.

Thanx

The first one has the most features.

The next two are the same just with a different colour readout

The fourth one looks agricultural compared to the others.

Thanx mate.
I had a feeling the fourth one isn't as "latest technology" as it claims.
Cheers
