thx a lot for trying to paint an overview.
I also tried to create myself an overview of the different Infiray models in the T2 series and in the T3 series.
T2pro, T2Splus, T2L, T2 Search,
and what makes it really confusing.. is that it seems that the apps, also vary... the search variant seems to be able to use the Infiray Search app (scope purpose), though not sure about the others, and the same with the Xtherm app.. some of the T2 series can use that app, and I got the impression that some models in the T2 series cant.
Same with T3 (units with 384x288 microbolometer sensor) where there also are a few T3S, T3, T3 Search, and T3pro, and then the Hti301/HT301 which seems to be identical to T3S.
I don't know what the difference is between T3 and T3S other then perhaps the lens size.. but maybe the T3 is simply a T3 search and some sellers list it as only "T3" without the "search"..
So 13mm lens for T3S and T3Pro and 19mm for T3search/T3.
the T3S is often quite a bit more expensive than the T3 on Alibaba and Taobao. which doesn't make sense if the T3S-lens (13mm) is even smaller than T3 (19mm) and everything else is equal. ?
A jungle trying to grasp an overview of the differences/models amongst Infiray dongles.
T2L seems to be an overall decent 256x192 dongle, but thats mostly because of the price that came across quite attractive with incl. EU vat and below the others - but also often delivers the somewhat cleaner & more contrast rich picture but the app seems to leave a lot to be desired and to an extent that Seek's app, almost seems spectacular good' in regards to Infiray's variant...
Not even sure that you can lock s given span on Infiray's native app.
so crucial to not let details get blown out and a feature that I use a lot on Seek's app..
Got a T2L in transit, after BG had them on quite low discounted price 2 weeks back.
example of span lock (Seek Pro FF iOS).. a pregnant 4S lipo-handwarmer and a battery testing rig with an electronic load...
