ZeroTech TRACE ADV 3-18×44 FFP Shoot2Hunt

I know that I’m in the minority, but I’ve been leaning towards the Monstrum scope caps. The rubber will split on them, but that is easily fixed/prevented by a few wraps of electrical tape. They are not as intuitive/efficient as the “both thumbs forward” on the Butler Creeks, but they are far more durable with the tape than the newest BC iteration. With just a little range time, the “caps away from the scope” opening becomes nearly as fast as the BCs.

They don’t stay closed particularly well

I’m enjoying the discussion on scope covers. Should we move it here and leave the guys alone who are only here for the S2H scope?

What kind of scope covers are you guys using? I was wanting to get some flip covers but im afraid to cover up the rear ocular adjustment in case it's needed. So what are you guys running? neoprene "Sock" style? Regular ole plastic slip covers?

Which ones have you tested and where do they split/do you apply the electrical tape?

I wonder if the State of California has considered requiring a consumer protection label on them yet?

They probably cause cancer in California.

It is my current pick for scope caps (with the tape preventative) even given their flaws. Once the ZTs arrive, the ODs of both the ocular and objective bells can be measured to determine the correct sizes of Monstrums.

Some of the zero techs have the screw threads to put a leopold style/tenebrax cap on. I wonder if the s2h scope has these threads.

Pretty sure they don’t but that would of been awesome

My steiners have an inner thread and I’ve tried to find the correct tenebrax cover for it. Funny Steiner ships with caps but they slide over top instead of threading in.

I'm struggling here, what am I missing?

While the s2h scope lists ocular and objective OD (46.5 & 52mm) I'm struggling to figure out because tenebraex website lists by scope make & model rather than providing dimensions and there's a mishmash of clamping around the ocular/objective vs threading in...

All of zerotechs other scopes (within the trace line at least) with covers don't list tenebraex part no's they just come as a set with the scope... I also don't see zero tech as a listed brand on tenebraex website...

The unfortunate truth is... Tenebraex is impossibly difficult to...

Thanks. I ordered the “pro” ones. Will try and report back.

Not sure there are any titanium reflex cans in NZ - and certainly not at 8oz. (If there are any ti OB/reflex, please let me know!)

Aluminium (Hardy, DPT, ASE, etc), yes. But Oceania Defence (ti cans) don't do OB/reflex, unfortunately. And the aluminium cans from the others are moderately heavy.

I have ODL cans, but am not overly impressed by either their noise reduction or the sound. Not super impressed by Hardy or DPT either, for the weight. Planning on experimenting with some of the Euro cans such as ASE, but, again, I think they're all aluminium (some with steel tubes).

The irony is that a few years ago, I tried talking Oceania into marketing their cans to the US, using Unknown Munitions as the distributor ... then UM went and started making ti cans that are superior to ODL's cans ...

I tried to get Oceania to print a few cans for me of my design but they wouldnt and said they had new cans coming out. I asked if they were planning to fill any if the niches I wanted and the answer was no. They said the intended to take some US companies to court over breach of patents or some such. My bet is they take ages and would have been better to take my money and print me some cans that may or may not have been effective.

In fairness otb or reflex cans arent all that. They are super inefficient in terms of weight. They add minimal volume require an inner and outer wall on the reflex portion meaning 2 walls for less volume.
I have had a ATEC Optima 45 and 45 Front side by side and theres so little difference its near impossible to tell the difference on my 223 and 22 Creed.

I would like to see some of the short titanium cans become available as our tech is falling behind.

They absolutely are Tenebraex compatible, the rear will even snap directly on instead of using a collar. It was touted as an initial design feature. But, no one can tell us what size yet. I’m sure Tenebraex can when the scope comes out.
