Gauge Doesn't Work

Jun 2, 2026 | By Jason Dierking

No complaints against the folks at Geno's but buyer beware on this gauge. It doesn't work and after several months of emailing back and forth with ISSPRO and shipping the gauge back and forth, it still reads completely inaccurately and they can't seem to figure out why. ISSPRO did send a replacement gauge but it does the same thing. Not sure what to do at this point.
