ANCIRS 4 Pack 2mm Needle Test Probes, 600V/10A Non-Destructive Multimeter Test for Fluke Leads tl71 tl75

Im able to easily check voltage on circuit boards and molex connections.

Worked well for my application

I'm an HVAC technician and routinely need to break out the needle probes to check voltage via wire connections, which means swapping leads. Loved my Fieldpiece delux leads right up to the point where I lost one of the regular leads down a wall while in an attic. Had to get replacement leads since FP doesn't sell the rebuild by themselves. Got a basic set and then was stuck swapping the entire lead set every time I needed the needle leads... which was a huge pain and waste of time. Theme slip right on several types of "regular" leads (fluke, southwire,...). They hold well and their resistance is within an acceptable range (>.5)... after you clean them (some kind of protective coating?). They are super convenient... The negative: I grabbed the plastic cone and pulled it right off the needle along with the black needle insulator when I was taking it off. Those was after about a week or two of use. It went back together just fine, but now I pull them off by grabbing the tip. A little annoying, but hey two sets were $10! I can deal with that since they're otherwise so convenient.

I design (and need to debug!) printed circuit boards for a hobby. With current surface mount techniques it is easy - and sometimes necessary - to pack components together tightly. This makes probing difficult with a standard multi-meter probe without shorting different pins together. Shorting then requires more debugging to find what component you killed. These "needle" probe tips slip right on over standard multi-meter probe tips, and eliminate that problem. The shafts of these probes are metal with a plastic sheath that leaves only a bit of the tip exposed. They are quite needle like and when pressed on a soldered pin, tend to NOT slip off. Very nice The plastic sheath slides up and down the shaft so, in very tight spaces, you can slide it down so only a tiny bit of metal is showing right at the needle tip. When slid up, this sleeve leaves around 1/8" of tip exposed.

Out of the bag, only 1 of 4 fit my leads. The one that did fit was perfect. I bent my leads trying to make it fit into one of the others. I was about to return them, but then tried a scratch awl to open the socket up. That worked much better than forcing a lead into it.
