I’ve got the Infiray Zoom ZH38. After using it for a season, I’m on the fence.
Pros: The optical zoom feature is nice, you really don’t loose clarity going from 1.6xto 3.2x. The ability to do this is great for adapting to the landscape you are hunting. In wide open country I scan on 3.2x, but can widen the field of view when in the thick stuff. The ability to go to 1.6x when recovering kills is great too. Battery life is fantastic, I’ve hunted all night several times and never had to use the extra battery. The InfiRay app is great too.
Cons: The picture image one my unit leaves quite a bit to be desired. We hunt from a high rack with 360 degree swiveling chairs, so you have the option to comfortably use your rifle scope to scan. My partner would consistently spot animals through his thermion xp50 that took me quite a while to pick up through the Zoom. I finally wised up and toward the end of the season started scanning with my xg50 lrf scope and only used the Zoom to recover animals. Most of our country is wide open and you can see at least 1000 yards. I don’t think any of this would be an issue if I only hunted thick county.
If I didn’t have the option to use my scope to scan with, I would be running a different unit. But I’ve already spent the money, and the zoom versatility is nice for my needs, so I’ll probably keep using it for at least another season or two.
