Power Probe Digital Thermometer
Wireless probe thermometer — how I document A/C vent temperature and coolant readings in every report instead of guessing at 'feels cold.'

UV Leak Detection Light & Glasses
A black light plus enhancing glasses — UV dye makes hidden oil, coolant, and A/C leaks glow, so 'it was just detailed' doesn't hide a seep.

Electronic Refrigerant Leak Detector
Sniffs out A/C refrigerant leaks electronically — a weak A/C on the lot often means a leak, and this finds it before you own the repair bill.

The tool that catches repainted panels and hidden bodywork — one reading per panel tells you more than any walk-around ever will.

Color-coded blades measure brake pad material through the wheel — the 8mm and 4mm readings in my reports come from exactly this tool.

A steerable camera on a flex probe — look inside cylinders, behind components, and into frame rails where eyes and mirrors can't reach.

The jump pack I recommend — 5000A peak starts gas engines up to 12.0L and diesels to 10.0L, with a voltmeter display so you can check battery state on the spot.

NOONE Smart Jumper Cables
Booster cables with a built-in polarity guard — the display lights up OK or WRONG before you connect, so a backwards hookup can't fry the electronics on either vehicle.

DEWALT Jump Starter & Air Compressor
The all-in-one trunk unit — jump starts, inflates tires with the built-in compressor, and charges devices over USB. Dead battery and a low tire handled by one box.

A scanner reads codes — it can't tell you a confirmed problem from something that needs further diagnosis. That's what 25+ years under the hood is for.
