For the money the Photon is a good VFM piece of kit. The on board IR is ok for short stuff but but it makes the image in the eyepiece sparkly.
At range this is not helpful. However a Marky light torch with an IR LED will change things totally.
Bearing in mind you will probably loose the VAT on one your into £333 so it isn't too far from £285.
Ask the user if there are any issues. Ask for the serial number and contact the company to see where it was sold through and if it has been back for warranty.
Also a £16 quid reversing camera screen from plugged into the video out gives a much better resolution image so you can double check quarry before you squeeze the trigger. On the TV screen the image is amazing.
The unit has two issues for me - firstly I don't like the ret - I prefer ladder rets so you know what to aim at for distances that are not on zero distance. the dot is OK but the dot size can make it difficult to zero at 100 on a rimmie HMR.
The other issue is the little tv screen in the eye piece does not have the resolution to show the CCD image as good as it can. High def video eye piece screens are pricey and this is not pricey bit of kit if you compare to some of the other digital or even tubed scopes and it is a very capable unit. So its the eyepiece that holds it back.
Get the IR LED torch and you will be stunned how differently this performs.
I am never keen buying stuff off the net though.
