Origin
Invented, not rebranded
The REM-POD, the Mel Meter, and the PSB7-PRO Spirit Box were built by Gary Galka. These are the originals, from the people who pioneered the instruments, not a reseller's relabeled stock.

Why Pro Measure
The instrument-maker's standard
A lot of paranormal gear is just sourced and rebranded. The instruments that defined this field were designed at our bench, and that is the bar everything here is held to.
Specs
Real numbers only
Every sweep rate, sensor range, and readout on this site is measured on the bench. If a spec cannot be backed up, it does not get printed.
Field-proven
Built for the investigation
These instruments are carried by working teams, including on Ghost Adventures. Designed for long nights in the field, not a display shelf.
Support
Talk to the makers
Questions reach the people who actually build and use the gear, so you get a straight answer instead of a script.

The Maker
Built at a bench in East Granby, Connecticut.
Pro Measure is the instrument line of DAS Distribution Inc., the electronics manufacturing company Gary Galka founded in 1983. A career engineer who spent decades building precision systems for Fortune 500 manufacturers, Gary is the original inventor of the REM-POD, the P-SB7 family of spirit boxes, the Mel Meter line and more than 30 other purpose-built research instruments.
Every instrument is designed, refined and supported at the same bench, by the same people who answer the phone. The gear has been carried on investigations around the world, including by the Ghost Adventures crew.
