I went out with both thermals tonight (no guns tho) to try to do some side by side video.
Dafty me forgot to put the memory card back in the DVR !
I'm really sorry about that because I was blown away by the contrast and sharpness of the image compared to the Guide and I would have loved to share that with other forum members.
However, I might get a chance to try again tomorrow night.
I mentioned that I was powering the new thermal from 2/3 of an Elwirecraft 1800mah battery
The reason for that is that there was only room for 2 cells in the small alloy box.
However it's not a problem because the thermal core runs on 2.5-5.5 volts and the OLED runs on 5-15 volts.
The solution was a simple 5 volt 3 terminal regulator.
Even although the regulator wastes a bit of power (appox 0.9 watts) I preferred it against a switching regulator because I didn't want any interference on the screen
The power drain is 2.3 watts which means the battery should be good for at least 4 hours
As far as I know, the only thermal commercially available in the UK with a comparable spec is this one
http://www.ketech.com/uploads/kescope.pdf
I can't get a price from them, they want to send a salesman round!
If anyone can get them to divulge how much they want for the 633 model, I'd be really interested
I note they advertise it as 25Hz.
Mine is supposed to be 50Hz and it certainly looks like that when you scan it around
Apologies for the rather rambling post.

Cheers

Bruce, that ketech thermal will be well over 10 grand, i would guess.......possibly even nearer double, a effing lot of money either way
when asking for advice, please include what n.v device and/or illumination you already have (if any) and what rifles you intend to use them on...cheers

Aye, Bruce, ye're some boy! fantastic, again! Must take a peek and compare with the 307, but I'm sure the higher refresh rate of yours will be a definite advantage.

Brilliant again, Bruce, now how about a decent guidance system for them wayward comet landing craft?? :clap:

Cheers,
