This model was made to be a Bushnell Custom clone (or a me-too),
with premium UVC coatings and BAK4 prisms, field-flattening in the
eyepiece, and deep irising.
I took delivery on an interesting pair yesterday, and did a nicotine cleaning,
a light WD40 grease cut on the objectives, and went through 10 Q-Tip swabs
with 91% IPA to clean up. The prisms?....later, just a few dits on them.
Cleaning notes:
1) You really must have an optical spanner for the clever mechanics.
2) Collimation is in part tweeked with aluminum shims on the threading of
the objectives...it can cross-threaded yet feel comfortable...be careful
and get the seating dead-level on the solid metal deck.
3) The UVC coating is has a death grip on any grease residue. I took a
chance on a little WD-40 as a getter and removing that. Finally won.
4) The threading is lovely but only after you clean the grit of prior flubs off.
After that, it comes apart beautifully like the old French binocs did.
The front and back covers are clamped under the parts and a little
elastic. I like that.
5) Tremendous fine-ribbed iris up front: does wonderful things for contrast.
6) Looks like a lot of prism faces can be got at as-mounted..will see later.
Usage notes:
1) fine threaded screw-thread eyecups: awesome
2) smooth solid focuser, though the diopter adjestment is a bit fast
3) very sharp resolution
4) contrast is very good: I'm hoping a little prism work will bring it to
excellent... the thing still reeks of nicotine. That kind of hazing is hard
to see by eye. Good enough for now That I'll get to it later.
5) Somehow I got the expectation that this would be extra-wide-view.
It's just 'wide': 8 degrees
Oh well..my 'scout' binocs are still the
stubby Taylor 7x35s with 525 ft @1000 yds.
6) Very solid build, all-metal, way past normal Jason kit.
Pocket binoculars, though heavy: very dense.
7) The view is clear and flat enough that there is this
eery "through a window", or "hovering in the air" effect
like I've seen in some cleaned WW-2 6x30s. Very comfortable,
but spooky. You just pick them up and .... there you are in the scene.
Not sure I understand it technically. Anyone have a similar experience
with a Custom?
Markings, since the web is low on information for this model:
Binoculars, Model: Jason Venture 4000 7x25, Model 106 , No: 1351
Other: "Compact 8-deg" , "UVC Optics"
I started looking and the "Buy Now" kept rising on EBay. Up to $48 I think.
Took 2 days off and came back to a Dutch auction: the "Buy Now"
kept dropping until I had to bite at $28. I might have a 'poor man's Custom'
...not sure until the prisms go through nicotine withdrawal.
