If you mean the new one is better than the old one then I think you mean successor, not predecessor
I suspect that your new Zulus has a new version of the firmware which improves its NV performance
Tell us the version of the firmware in your new model

The new firmware didn't improve the old ones issues but it did centre the ret above base mag.
I will take a look later re the firmware.
Cheers.
Is it holding zero with just two bolts used instead of four ?Not a good start...they overnighted the unit and returned my old mount.......minus the m5 cs screws.
Just found two and cut to length.
The mount can wiggle from side to side and needs shims! Come on Arken!!View attachment 372127

Yes, the old one did too.
I need it to reach back.
The instructions, iirc, says two is minimum but don't quote me.
Good to hear thanks.

I think for the sake of £35 I'd get the long reach mount and use 4 bolts.
Mines on a 308 so I didn't want just 2 bolts holding it on with the recoil.
A cautionary tale and a possible reason for the problem Smellydog had with his Zulus switching off/doing weird stuff when used on his 222
A friend of mine bought a Zulus 520 with LRF
It turns out that when the scope was brand new, another pal saw him try to use a button top 18650 battery and try really hard to screw on the battery cap
He was told to use a flat top 18650 which he then did and proceeded to use the zulus on an air rifle and a 22 rimfire without any problem
When he put the Zulus on his 222, it switched off on the third shot. I tried it on a 243 and it switched off on the first shot
A bit of investigation which involved removing the 4 screws that hold the front of the scope onto the main body indicated that the spring which forms the positive battery contact had been over compressed, probably by trying to fit the button top battery
Simply stretching the spring back into it's correct shape has resolved the problem
With the scope mounted on a lightweight 22-250, I fired 10 shots without the scope switching off or doing any weird stuff
If anyone else has this problem, it's not necessary to open the scope if you can lay your hands on a hook type tool that can go inside the battery housing and grab the spring so that it can be stretched back into the right shape
Another alternative that will almost certainly work is a thin (1mm thick) disc magnet stuck to the negative end of the battery
I repeated the 10 shots on a 22-250 procedure on my own zulus 3-12 and 5-20 - both of which have only ever used flat top 18650 batteries and neither scope switched off or did any weird stuff

Good post as ever thanks MJ.
Just why some people force button tops into flat top housing is beyond me!

All my cells are flat top but yes its a good point @mealiejimmy 
Because the world is full of people who:Good post as ever thanks MJ.

a. Don't read instructions
b. Don't realise there are different types of 18650 batteries
c. Already have 18650 batteries they use with torches (which usually have button tops) and just assume that those batteries will work

Yep - ever thus ….
So today playing with the Zulus (practicing pressing record button etc) and twice upon firing recording stopped and a message came up saying “SD card too slow ..”! Turned it off and on, pushed record and next 4 shots caused no such problems!
This is the same card I have used successfully (ish!) since I bought the Zulus - how very odd!
Offers??
I will try that as mine switches off when it's on my 6.5prc, but not on my .223 , it's never had a button top battery in
Agree with the 1mm disc magnet. I've got the 2mm and the battery cap only screws half way on.
Does anyone want a 2mm disc magnet as they come in 20's?
.Hi guys I have just bought a Zulus with range finder and balistic data. I want it to shoot rabbits on an Anschutz ,.22 RF rifle due to noise restrictions. using .22 RWS subsonics, There is no muzzel velocity data on the box what data should I use?
bullet data 40gr but what length?
has anybody set one up for a .22 RF that could help me with all the required data would be very much appreciated as it is a bit of a pain with all these multi function buttons and very poor instructions. kind regards

We need @mealiejimmy and @Jelen to assist.
I think the are two options. One maybe the G7 for your needs.
Rws subs are probably in the high 900 FPS.
