Frequently Asked Questions - Duovid LEICA

How to adjust the diopter correction on Leica Duovid binoculars?

To adjust the diopter correction, first focus with the right eye using the central focusing wheel. Then pull the diopter adjustment ring (on the left) to unlock it, and turn it until the image is sharp for the left eye. Finally, push the ring back to lock the setting. The selected value is shown on the scale. Make sure the left magnification ring is in its end position (8x, 12x or 10x, 15x) before unlocking the diopter.

How to change the magnification on the Duovid?

Turn the rotating rings located under the eyecups. Both rings must be placed in the end position (stop) to ensure identical magnification in both eyes and to enable automatic diopter compensation. Intermediate positions are possible but not recommended.

Can I use the binoculars with eyeglasses?

Yes. For observation with glasses, retract the eyecups (position b). Without glasses, extend them by turning counterclockwise (position a). The eyecups snap into position.

How to clean Leica Duovid binoculars?

First remove coarse dirt with a brush or by blowing. For fingerprints, breathe lightly on the surface and wipe with a soft cotton cloth. If the binoculars are very dirty, you can rinse them under running water. Make sure the two halves of the central focusing wheel are coupled to prevent water entry. If exposed to salt water, rinse with fresh water.

Are the binoculars waterproof?

Yes, they are waterproof to a depth of 5 meters. The housing is nitrogen-filled to prevent fogging, making them suitable for harsh outdoor conditions.

How to attach the strap?

Pass the strap through the lugs on the housing (mark n°5). For the case, open the top flap by undoing the snap fasteners and thread the strap through the side slots.

What is the minimum focusing distance?

For the 8+12x42 model, the close focus limit is 3.50 meters; for the 10+15x50, it is 3.80 meters. Beyond infinity, the extension is -4.5 diopters.

Can I use a tripod with these binoculars?

Yes. A tripod adapter with 1/4" thread is available. It is included in the kit for the 10+15x50 model. It allows stable, prolonged observation without risk of damaging the binoculars.

How to adjust the interpupillary distance?

Spread or bring together the two barrels around the hinge axis until the two fields of view merge into a single bright circle. The adjustment range is 56 to 74 mm.

What are the important safety precautions?

Never observe the sun or any intense light source with the binoculars, as this can burn the retina. The device is not suitable for direct solar observation.

Warning notice

As with all binoculars, avoid looking directly at sources of bright light with your Leica Duovid as this could cause eye damage.

Possible applications

The Leica Duovid is a high-performance set of binoculars with two magnifications that can be selected as required. The lower magnification provides a bright, stable image with a large field of view and a large depth of field. The higher magnification offers outstanding recognition of details of distant objects and in conditions of poor light. The balanced weight distribution and the perfect ergonomics combine to give an extraordinarily stable image despite the high magnification.

The Leica Duovid has a hermetically sealed, nitrogen-filled, and die-cast aluminum housing. It is therefore suited for rough outdoor use. There is no need to be concerned with moisture as it is 100% waterproof to a depth of 5 m and the internal optical system is not subject to fogging.

Attaching the carrying strap

Attaching the protective eyepiece cover

The eyepiece cover is placed over the eyepiece cups. It is fixed using the carrying strap.

Care and maintenance

Your Leica binoculars need no special maintenance. Use a soft lens brush or a blower to remove large particles of dirt, sand, etc. To remove fingerprints etc., first wipe the eyepiece and lens with a damp cloth, then dry them with a piece of clean, soft chamois leather or lint-free cloth. If the binoculars, particularly the telescopic eye-pieces tubes, are very dirty, rinse them in a basin of water rather than under a running faucet.

Always rinse off salt water.

Moisture inside the central focusing unit (visible through the scale window) will dry quickest when the diopter adjustment ring (4) is pulled up, i.e. unlocked.

Tripod Adapter

This practical tripod adapter is equipped with a 14 " thread for all Duovid models and allows long-term shake-free viewing. In the case of the Leica Duovid 10+15x50 it is included in the scope of delivery.

Carrying case

The soft leather carrying case supplied with your Leica binoculars protects them from dirt. A flap with snap fasteners is provided at the top of the case, through which the carrying case strap can be fed.

Adjusting the eyecups

The eyepiece cups (1) can be easily adjusted by turning them and they lock securely into the selected positions. They can also be completely removed for thorough cleaning.

For viewing with eyeglasses (Figure A) they remain in the fully screwed-in position. For viewing without eyeglasses, they are unscrewed

by turning them anticlockwise. Two positions are available for optimum adjustment (Figure B, C). If the eyepieces are very dirty, it is recommended to remove the cups for cleaning (Figure D). To do this, they are turned slightly back clockwise and gently pulled while in the fully unscrewed position.

Adjusting the eyebase

To set the eyebase, adjust the binoculars at the hinged joint. The left and right fields of view must merge and produce a single circular image.

Setting the magnification

The Leica Duovid offers the user a choice of two magnifications. The magnification is adjusted using the adjustable rings (2) below the two eyepiece cups. Both rings must always be completely moved into the appropriate end position.

Notes:

Intermediate settings are possible, although identical magnification in both optical systems cannot be guaranteed in this case. Furthermore, the automatic diopter setting (ADC™ – Automatic Diopter Compensation, see also the next section “Focusing/Diopter compensation”) only applies in the two end positions. Incorrect settings can therefore quickly lead to a strain on the eyes and to fatigue.

As the left ring is linked to the automatic diopter setting, its movement is slightly stiffer than that of the right ring.

Focusing/Diopter adjustment

With the Leica Duovid the central focusing ring (6) is used to set the focus for variously distant objects.

Note:

The focusing of the Leica Duovid is retained after the magnification is changed. However, a slight adjustment can be required in practice. This is especially true when changing to a higher magnification after having focused with a lower magnification. The reasons for this are the larger depth of field at lower magnification, which often leads to slightly less precise focusing, and the eyes' accommodation capacity.

Close-up of a black binoculars with visible lens and focal points (no text or symbols on the bin itself)

Compensation for individual defective vision for viewing without eyeglasses is made using the diopter ring (4), which is normally locked. (Figure A). First of all, the central focusing ring is used to focus the right barrel on an object. The diopter ring is then released by pulling it up. (Figure B).

Attention:

If the left magnification adjustment ring is not in an end position, i. e. at 8x or 12x/10x or 15x, the diopter ring is locked and cannot be released.

The diopter ring is then twisted to set the optimum focusing for the left barrel. Pressing the diopter ring back down locks the set value. Defective vision differences of up to ±3 diopters can be compensated in this way.

Attention:

Do not adjust the magnification with the diopter ring released. The left ring for adjusting the magnification is locked when the diopter ring is released.

For viewing on just the left or the right side, the other eye should be kept closed or the appropriate half of the binoculars simply covered at the front on the lens.

The set value can be conveniently read from the accurate scale on the diopter ring.
