Duc, and I take him on a plane...no problem. My backpack weighs about 30 kg (along with an ice pick). I don't recommend buying it right away, but try it out and then decide whether you need it or not. Their prices have gone up. A good, light ice axe (with a good bayonet), suitable for setting traps, now costs at least 2100 rubles.
I have an ice pick like in the photo:

Only the bayonet was replaced with a metal, more durable one. The regular one broke down from loads (I turned very large stones over). Now it's not killable!
We live in the same city, I can send it without any problems. If you think about it, please let me know in advance, because I have it now outside the city, but within quick reach.

Maybe not in the subject, but about traps.
There is such a task - to hang a series of traps at the same height (up to 15 m) at an equal distance from each other. In natural biotopes, this is almost impossible to do. But there is one bad idea - to use power transmission poles, since there are enough of them everywhere now. Tell me, good people, is it really dangerous to climb the poles of power lines?! How illegal is this? (what happens if they get caught? - I don't cut the wires). How often do electrical insulators "leak"? Will boots and rubber gloves help?! The method of setting a trap by casting a cord with a weight will also not work: the cord will get wet during the exposure, and then it will work by grounding.
These are such naive questions. I think to bury the idea or assign it to the student

A student should probably not be instructed to climb high-voltage cables, otherwise there will be a trap for corpse-eaters, anything can happen. The tension there is serious.

Equal deletion is not required. You can also interpolate non-equal distance on a uniform grid. Better bury the idea than sacrifice the student. And the ultrasonic height can be measured with a laser rangefinder with an accuracy of up to a millimeter.
