I also have a 335R, the 'mid range' (£1800) of the 3 units from DNT. I zeroed the digital part on Wednesday, figuring I'd zero the thermal side another time. The thermal is to be used as a spotter, for as Bruce says swapping from a separate thermal spotter to digital scope, it's often hard if not impossible to find a potential target when searching with digital.
No issues with this multispectral, it's all there on the screen.
Even though it's currently a little off, finding the deer through the thermal (via Picture in Picture) and putting the digital on target was simple. I had shot a fallow doe beforehand in the wood and was back at the car looking across a field when I took this short video - just playing around as you do with a new piece of equipment, not actively stalking.
Please remember, this is an iPhone screenshot of a video replay, so the quality isn't close to what you actually see when looking through the scope.
What you can determine is that, at nearly 7pm a few days ago, so properly dark:
1. The thermal works just fine, almost comparable to my Helion XP 38
2. the onboard lamp illuminates easily out to the 236m as indicated, it was only on level 2 of 5.
3. The rangefinder puts a nice red + when compensating for distance
4. In pitch darkness, differentiating between a doe & buck is straightforward.
5. The battery lasts hours, put the unit on standby and when fired up again, it comes back on almost instantly, with the lamp at the same intensity as when put on standby.
6. The field of view isn't great, especially compared to my XP38, but a small price to pay for all the above.
In daylight, there isn't any need to swap to an optical scope, such is the level of detail. I identified a roe buck at 418m without difficulty, when zoomed to x20. It isn't like traditional stalking however, looking through a quality scope. But on this permission, deer need to be shot and they are becoming more and more nocturnal. I'm on 48 deer since April on this area alone, 16 up on previous years with 1 1/2 months to go.
Very happy so far....
