Have the HF meters changed? I've had no problems using any normal shrouded leads with mine. Around $6 shipped on ebay gets a decent set of leads. I usually search for cat 20 leads with or without silicone as a search term.
You need to investigate safety Cat ratings.
Sears has Craftsman multimeters on sale until Christmas for $9.99, regularly $19.99. I just bought another one to keep in the vehicle. I’ve had my first one for about 4 years and it works great. I have had the HF models before and they’re trash. Only thing it’s good for is a paper weight.
I must luck out on every package I buy then. Never broken one without actually trying to. I only use the two largest sizes they carry in black.
you can always cut off the ends of the Hf leads and install a clip or connecter that suits how you are using the meter to test components.
No joke. Although the meter is not the most accurate in the world, it'll at least tell me if I have power to a 120V outlet or not. I'm very surprised they would have proprietary test leads for their meter.
This. I've used hundreds and none have broken.
How often does it get to -10 F there?
Correct! Just say no to anything under Cat. III meters. This piece of garbage is a Cat. II. Avoid at all costs, unless you are just using it for 24 Volts and under.

Do these replacement leads fit correctly with the $5 (or free) HF Multimeter? https://www.ebay.com/itm/1000V-20A-...193273707482?_trksid=p2385738.m4383.l4275.c10
I keep them around to customize and/or cannibalize for specific (low energy) uses. I put an XT60 power connector on this one to quickly check the voltage of drone batteries without unwinding the leads.
They'll fit if the shroud over the banana plug is trimmed back.
I bought some like that a few years ago. There's no way they are good for 20A. More like 5A. Otherwise, they're not too bad. They were cheaper back then.
If I were to get more, I'd much prefer a domestic source. International mailing can get wonky these days.
