Here is another one that I found a few days ago.

Probably worth keeping your eye on cavers comments and reviews such that when the switch in your Duo or the connections in the battery box go intermittent in 6 - 18mths, you already know what to replace it with.
Maj.
We have working old duos with the CustoDuos fromBif still working. Original duos from the 90's mod done in 2010ish.
Often what goes wrong is the connector in the battery box gets coorododed or bent out from touching batteries from too many whacks. Coorosion - clean. Bent - bend back.

2 other ways a duo can go wrong.
1) old rechargeables- replace rechargeables with new (they only last so long!).
2) Battery insert wobbling when catches are engaged- (2 solutions)
-- a) put some folded cardboard around the plastic at the bottom of the insert, stopping it from wobbling away from your head (and disengaging from the battery terminals).
-- b) replace the insert with a new one to stop it wobbling.
I've had my 16 led (now Custom) Duo since about 2009 (from new), used most weekends and still strong!
edit: insert was replaced, as it was letting water in
I'm not entirely sure what 'wobbling away from your head' means regarding the battery insert.
Do you mean the bottom of the battery holder moves slightly back from where it should be inside the box?
What's the diagnostic method - trying to tilt the lid in situ, and seeing what happens?

Yeh, sorry, it made sense to me :s (at the time).
Imagine the battery insert pivoting around the yellow plastic at the top. If you try to wobble (pivot) it around that point while the clips are on, in normal operation there should be no movement.
I found that my insert WAS wobbling. If you take the insert out, and look at it as though your going to put batteries in (palm of hand, fingertips on the yellow plastic and base of the insert at the heel of your hand). I put cardboard on the section of plastic facing you near the heel of your hand.
Doing this wedges the batteries in the insert against the contacts and stops them jiggling around.
I gave up on this, as already stated, my battery box was taking on water (mayday mayday!) so replaced the insert.

What do you think about this headlamps? You can buy them at Gearbest for about 30-35eur. They are very similar to zebra lights. Also one question about this type headlamps. How do you use them for mapping, because of their magnetic field wich interfere with compas.

I have one of these H03 basic versions. I really like it. Well made and the settings allow you to tweek the levels for your intended use without having loads of settings to cycle through. I personally find the spread of light good for caving, not too much beam and not too much spill. My only real negative is that the colour temperature of the LED is not to my liking.
The magnet is held into the base with a spring clip, so you can very easily remove it. I think that it even came with a silicone disk to replace the location where the magnet came from. So no issue for surveying.

As I understand the battery itself create magnetic field which intefere with compas.
What Skilhunt model you use? With floody (TIR) or spot optics, neutral or cold white light?

I have the TIR in neutral, which I find to have a very slight green tint on the lower settings.
You are correct in saying that the battery causes a magnetic field, and this is the case with all of these 'zebra' type lights. However the field is relatively small in comparison to the magnet I removed. Having a play with a few of my 18650 cells in this light, they started to affect a compass when within about 60mm. This is far enough not to affect my setup, but you would need to be aware of this affect if you setup was tighter or you were sighting in a constriction.

Would you recomend this skulhunt lamp? What do you think about spot light model and what are the diferences between neutral and cold white light. I am planing to buy one of these but I am still in doubt what model to choose.

For the price it is a good light. I use it regularly at work and as a backup for caving. The neutral is a warm white/ yellow tint but as i say I find it a bit green in the lower settings. The cold is more blue. It is just down to personal preference. I haven't seen the beam pattern of the OP light, but I don't like caving in a beam, so I suspect that I would find it too tight. The TIR works well from my point of view.
