Advertised as "undetectable"and "foolproof" for beating urine drug tests, the so-called "Whizzinator" proved otherwise for a Butler man.

Ryan Dennis Hartzell, 26, of Evans City is accused of using the convoluted contraption during a recent visit to the Butler County Adult Probation Office.

He was caught — literally — with his pants down, wearing the device rigged to look like a fake penis and bladder.

The arrest was a first for longtime county Detective Pat Cannon, who on Tuesday charged Hartzell with a misdemeanor count of furnishing drug-free urine.

"I never ever heard of 'The Whizzinator,'"he said. "I've arrested people for using balloons or other things to beat urine tests, but nothing like this."

Hartzell's latest trouble with the law came March 26 when he reported to the probation office for a urine sample. That was part of the terms of his probation stemming from a 2007 conviction in a theft-related case.

But the sample didn't look right to probation officer Joe Gigliotti.

The defendant was told to lower his pants, which revealed "a tube protruding from (his) boxer shorts,"according to court documents.

He admitted it was no ordinary tube, but was The Whizzinator. He said he bought the device on the Internet.

"(Hartzell) admitted the purported urine that he supplied to Gigliotti,"documents said, "was not in fact urine at all."

The Whizzinator, according to its Web site, is a urine substitution device. It delivers a toxin free urine sample through a light weight apparatus that is worn under clothes.

The product sells for $150; its home page states the dehydrated urine used with the device is sold separately.

The phony specimen, produced by blending water with the urine powder, is placed in a bag attached to a belt.

When Gigliotti described The Whizzinator to Cannon, the veteran detective initially couldn't believe his ears.

"I thought he was kidding me,"Cannon said.
