My Rambling Thoughts

Sky Rover Acuity 8x32 bino

I decided to buy the Sky Rover (天虎) Acuity 8x32 ED binoculars from its Blade (刀锋) series. I don't really need it. It is more of a "holy grail" — it is an entry-level 'high-end' bino. :lol:


Sky Rover Acuity 8x32

It boasts some impressive specs:

  • 8.2° FoV
  • Flat field
  • 90% light transmission

I got it for its wide FoV and flat-field. I now feel flat-field is essential for wide FoV.

8.5° or so seems to be the 'limit' for 8x32 roof binos. Over that, the bino gets too big/costly and you might as well get a 8x42 — where the high-end is over 9°.

90% light transmission seems low, but I believe it is real, unlike lower-end binos' claim of 92+%. Let's see how it compares against the SV202, my brightest bino so far.

Now that I have four binos, I need to get rid of one:

  • Reasur (阅森) Traveler (旅行家) 8x32
  • Shengtu (圣途) Forester (森林人) 8x32
  • Svbony SV202 8x32 ED (same as Shuntu SHA15 8x32)
  • Sky Rover Acuity 8x32 ED

Reasur Traveler 8x32 is a low-end bino I bought for casual use. It is surpisingly decent, despite having no phase coating nor dielectric mirror. I regret not getting the full-white model.

The Forester 8x32 is big and heavy and has nothing special going for it. When I got it, I thought 7.4° was big for 8x32! It turned out not to be the case. Its only saving grace is that it seems to have very honest specs.

The SV202 is supposed to punch above its weight. At first glance, it performs well optically. But more discerning observers have noticed distortion, blurry edges and CA (despite ED glass).

I will decide after comparing how these binos perform optically in terms of sharpness, field curvature (zone of sharpness), vignetting, flare, distortion, CA (Chromatic Abberation) and brightness.

Iran at breaking point

Iran's 6/4 is here.

Who will prevail?

In any case, a regime that fires on its citizens has lost its mandate.

Two crackpot Maduro theories

USA's lightning fast and smooth surgical special operation to capture Maduro alive on Jan 3rd has taken the world by storm.

Prior to this, every pro-China shiller loudly proclaimed USA would not dare to invade Venezuela for two reasons: its strong military defence from its state-of-the-art radar system and missiles, and China's unwavering support.

How did USA manage to execute such a smooth operation? Is it really so advanced technologically?

At that time, I already thought there was more than meets the eye. As days passed, it was revealed that USA had inside help: they had informants providing key intelligence.

But was it just that? The head was gone, but the entire Government appartus remained. They could continue his policies. But it was telling that the military remained silent and everyone was ready to move on.

This made me think USA had achieved a deal with key members of Maduro's Government. Everyone was sick and tired of living in poverty — Venezuela is a resource-rich country!

There was one obstacle: Maduro.

USA came with a deal: they take him, and they'll remove the sanctions on Venezuela. Of course there are other conditions as well (drugs and China), but if Venezuela can have a normal economy, why would it to resort to these?

As the week unfolded, this seems to be a likely theory.

The other theory that I came up with is more outlandish. Maduro allows himself to be captured in return for safe passage. There can be a few reasons why.

One, he is only a figurehead. He wants out, but the powers behind (drug lords?) will not let him go alive.

Two, he believes he is going to be assassinated or ousted. This is not surprising given his unpopularity.

Three, he is actually a 'hostage', a puppet controlled by foreign powers. His core bodyguards were all Cubians. It is said he does not believe in locals. What if they were actually keeping him under close watch?

Then it becomes unsurprising that the Cubian 'bodyguards' all had to die in this operation.

I find it strange that his wife was captured along with him. Normally you just want the man himself. But his wife too? It sounds more like a rescue than kidnapping.

What's in Greenland?

The most obvious is rare earths. But when Arctic ocean thaws and the Northern Sea route opens up, Greenland becomes strategically important.

This is the most likely way for Straits of Malacca to lose its dominance. Many countries have been trying to bypass it for decades, but without success. The countries involved are too poor to afford the project. China can do it, but it faces ownership risk.

On the other hand, the NSR is a natural optimal path from China/Japan to Europe and USA — if not for the ice.

It won't happen soon, but it is hard to say in 20 years time. And once it happens, there is no turning back. Singapore will lose relevance as a port forever.

How serious is USA now? Not very, IMO. It is sounding out other countries and 'staking a claim' — in case other countries (*) are also interested in the future.

(*) Everyone know which country this is.

Even car rental can go bust

Autobahn Rent A Car has 1,700 vehicles and owed over S$300 mil. The cars were from 2022 to 2025.

It was noted some of the cars lack insurance and do not have valid road tax.

It looks like demand was not that strong after all.

1,700 is only a drop in the water. There are 90k Private Hire cars.

Could car rental companies be one of the reasons why COE went up so high? Perhaps, but LTA did not provide any figures.

LTA is pretty pro-PHV in recent years. No doubt it feels a shared car is more 'productive' than a private car.

A PHV loan can be 100% stretched over 10 years. Compare this to 70% (60% if OMV exceeds $20k) over 7 years for normal cars. The downpayment is a barrier.

LTA issued an advisory for car buyers to obtain financing from legitimate, regulated companies. Between 0% and 30% downpayment (which can be $30k to $50k), which do you think they will choose?

Let's see if a few more car rental companies throw in the towel. 2026 is a year where the tide goes out.
