Pogo Pin Probe Clip
The Pogo Pin Probe Clip is a great way to test and connect with pin-point accuracy without soldering! It's sort of like an alligator clip with a built in springy pogo pin - so you can connect to any PCB pad for 'scoping, analyzing or multimetering
The clip is strong enough to grip onto a PCB, but has a soft grip so it won't mar or damage circuits. The 'tongue' is a round-tip pogo pin - a little spring-loaded contact that's very handy for making momentary electrically solid contacts. The continuity goes through the clip and out to a solder-friendly crimp connector.
You could also use this for connecting to batteries, wearables, just about anything where you wish you had a third/fouth/etc hand to hold a probe in place.
