Hi Richie,
If you want magnification for long range foxing, then the cheaper T-Ceptor PRO 55-3 would be the one to go for with 6x base mag. The image quality of the target for a given magnification, poor weather performance and user experience is exactly the same as the 55-6. You just loose the wide FOV on the bottom end.
This video will give you a rough idea of what you can expect to see through the 55-3, albeit the video is 1/4 - 1/2 the visible quality through the scope itself depending on the zoom level.

In terms of pixellation when zooming, it doesn't really do it as the image is upscaled each time to the display. It never turns into 'Space Invaders' as a lot of other units do. Also if you do use digital zoom, the image is re-exposed, further enhancing target detail. Nothing else does this.
It's a small, lightweight, robust unit with rock solid POI and reliability and we build them here in the UK.
We've trialled bigger lenses on the platform, but it was a waste of time and would be a waste of money for our customers. Targets were bigger, but no more detailed due to the limitations of the lens material and layout of elements required for a rifle scope to maintain POI during focusing. No different to applying a little digital zoom on the 55mm lens which is already optimised for highest possible resolution.
You can quite easily visually ID a fox at 450+ yards and shoot it if you can put the bullet in the right place. I'm not sure what more is needed.
The image processing is hardware based on a dedicated chip, rather than the usual firmware loaded onto a microprocessor so it does an awful lot more, an awful lot faster than other thermal cores. There is no lag or delay to the image.
It's not an overly expensive scope due to us manufacturing it and selling direct to the end user, but it is assembled from comparatively, very expensive components which shows in the resulting performance.
Hopefully this all helps.
Cheers
Clive
