940nm IR

Post by Ttocs » 24 Jun 2018, 08:53

Hi, is anyone using a 940nm IR with a Dron Pro 10x. Found my first IR shy fox the other night. As soon as I turned on the 850nm IR all I saw was a flash of eyes as it turned and ran in the other direction. So wondering about fitting a 940nm lED to my sunranger but wondered if the Drone 10x is sensitive to that wavelength and are they completely covert when in use,if so, how do you know it’s off without switching in the NV.
Thanks
Ttocs

"In general" the 940nm illuminators are a waste of time, they just dont have any realistic range, i'm not saying that if you have one already and you know that you can get within shootable range of the fox with it, that its worth a try, but you carnt always predict the range the fox is going to be at.

I have had foxes that have been I/R shy, some times because i or some one else has shot at them and missed them, a good tip for foxes like this is to change the direction you come at the fox, ive had these's "missed" foxes look out for me from the direction they are used to seeing me, a change of direction can give you the extra seconds that you need ------keep at it, the i/r shy fox will eventually make a mistake, keep your i/r movement down to a minimum.

Some times other factors coupled with the i/r can spook the fox
(1) stopping in a vehicle then i/r is turned on
(2) turning i/r on then loading rifle
(3) bipod noise, ect, ect

Ive spotted a lot of foxes when ambushing them with my 850nm vehicle spotter, none have spooked with this alone, the i/r is on all the time and movement is minimal.
These's wild life camera's use black flash ie 940nm, the foxes still see these's, some will spook but most dont------some times after a while.

Someone must be shinning an 850nm over my shoulder when I use the built in 940nm on my N355 as I can clearly see foxes over 200 yards away!

If you get the chance try a Ruby sunranger on all its 3 power settings with your N355, in an open field, against any 850nm IR and tell me what you think please. I am not going to say anymore because I don`t want to influence your findings and I am not sure if it was me doing something wrong the other night, but it was very interesting.

Phil, i'm not saying that YOU carn't see foxes at 200 yds with the built in 940 ir of your Pulsar n355 ------ive never looked through one, but the OP is asking about using a 940 ir with the Drone Pro, i have used a Pulsar 940 i/r with the Drone Pro and i couldn't see foxes at 200 yds.
The Drone Pro isnt the best at working with the lowest i/r, it needs quite a bit to work, the newer A S type pills or Ruby have really improved the performance to silly levels, usually without "whiting out".

Dave I am aware that 850nm gives better illumination at longer distances, and I can only speak about the kit I have used.
The bulit in 940nm on my N355 has no problem picking up foxes at over 200 yards. I use an old Pulsar monocular (can't afford a thermal spotter just yet) with a built in 840nm to scan the fields. There are a couple of foxes on my shoot that are IR shy so I have ordered a PBiR-X in 940nm for the spotter.
