Isn't better to use a powerpack to charge the DistoX2 than fidle with batteries and calibrations?

Actually, I was talking about replacing the non-magnetic LiPo battery. A powerpack is probably my best bet, becuase who doesn't need a break after that many hours anyway.

It is so sensitive think, that the best way is not to replace it. :)

To be fair, I was also considering making a plexiglass jig to make it easier to calibrate.

I am now the proud owner of a Disto X2! Here's the problem: I have no bluetooth device that can run the software yet. Is there a way to calibrate it without that?

1. You may run PocketTopo program on Windows too. So measure in good conditions all 56 shots and go to PC and transfer them there.
2. You may run on Android device TopoDroid and calibrate from there.

A Bluetooth-capable PalmOS PDA can be had for 10$ on eBay

You may then use my user-friendly calibration freeware.

I am about to modify a Disto X2 and saw the discussion about the USB charger installation, most people soldering it directly to the battery contacts, but some having issues with breakage. It seems like it might be ideal to leave out the USB charger circuit until one needs to actually charge the battery, as it could contribute to magnetic influence, and the device only needs it installed during charging.
I am tentatively planning to make a little USB charger snap in block instead of soldering it in permanently, by mounting the USB charger into a plastic block which is the same size as the two AAA batteries, with the USB charger contacts touching the disto battery contacts, and then just installing the charger block into the compartment only when charging is needed, see example pic of the block, which will need to be modified to host the charger once it arrives. Any problems or suggestions for this mod?

Just remember that one set of battery contacts also needs to be removed. That may affect your design somewhat.

I considered a similar thing, and have not installed the USB jack yet. On a recent trip, I had my DistoX battery die, and could not recharge it in camp. If I had a commonly available connection, like say, Micro USB, it would have been a snap! That is to say, there is some advantage to having a common, not easily forgotten, connection scheme.

Considering a bunch of silicone to reinforce the jack once (if?) I do put it in.

Another path I have considered is to make a USB cable with alligator clips. Risk there is backwards connection and frying the DistoX/battery etc.

A note on the physical mods that I ran up against.

I removed the end piece entirely, in part to get of the magnet, and also to give a nice spot to connect a lanyard. I left the axle in place.

What I did not realize until later, is that the end piece acts in part as a "lock" for the battery compartment. With the end piece in the folded position, the battery compartment does not open. With it gone, there seems to be the possibility that the battery compartment door could more easily get opened and lost in cave.

Snoboy thanks for the feedback and suggestions. When you say that one set of battery contacts need to be removed, are you sure of that? I figured the top contact was just completing the circuit between the two batteries to keep them in series, and as long as I used non conductive plastic block it would not matter to leave the springy top battery contact in place. But I have not opened it up to confirm if the top contacts are wired in somewhere. Or is their a magnetic reason to remove the top battery contact strip?
I plan to leave the extension end piece installed and just machine away the tiny magnet in it. It looks like it will not line up perfectly with the laser axis, but will only be out about 3 mm.

I think it is removed to reduce magnetic influence. It is in the build instructions anyways. It just pulls out.

That's what I did. Color coding the alligator clips, color code the contacts, pay attention like you might fry a $600 device, and you'll be fine. Soldering the mini USB connector to the springy battery terminals wasn't mechanically secure enough for me, so I removed the USB connectors and used the alligator clips.
