A SCRAM ankle bracelet is a court-ordered monitoring device that tests for alcohol through your skin every 30 minutes, 24 hours a day, usually after a DUI or another alcohol-related offense. The name stands for Secure Continuous Remote Alcohol Monitor. If a judge has ordered one, you’ll wear it for a set period, often 90 consecutive clean days, while a monitoring company reviews your readings and reports any drinking or tampering to your supervising officer.
How It Detects Alcohol
The bracelet uses transdermal alcohol monitoring. Your body releases a small amount of alcohol through your skin as perspiration, and a sensor on the inside of the device captures that vapor from the gap between the bracelet and your ankle. It calculates a Transdermal Alcohol Concentration (TAC) reading from each sample.
Testing happens automatically, without any action on your part.1SCRAM Systems. SCRAM Continuous Alcohol Monitoring Quick Facts Because the sensor never shuts off, the record it builds is far harder to beat than a scheduled breathalyzer. The device targets ethanol specifically, which is the type of alcohol in beer, wine, and liquor. It also distinguishes drinking from environmental exposure by reading the shape of the alcohol curve. Drinking produces a slow, smooth rise and fall as your liver metabolizes the alcohol. A splash of hand sanitizer near the bracelet produces a sharp spike that drops off almost immediately as the substance evaporates.
CAM Versus GPS: Two Different Devices
Not every SCRAM bracelet does the same thing, and people mix them up constantly.
- SCRAM CAM (Continuous Alcohol Monitoring) is the alcohol-testing bracelet most people mean when they say “SCRAM.” It does not track your location.2SCRAM Systems. Do SCRAM CAM Bracelets Have GPS?
- SCRAM GPS tracks location continuously for curfew and exclusion-zone enforcement, but it does not test for alcohol.2SCRAM Systems. Do SCRAM CAM Bracelets Have GPS?
Some defendants wear both, one on each ankle. No single bracelet combines the two functions.
Products and Habits That Can Trigger a False Positive
Ethanol shows up in a lot of ordinary products, and the sensor doesn’t care where it came from. The safest habit is to read ingredient labels and avoid anything with a word ending in “-ohol” (cetyl alcohol, stearyl alcohol, cetearyl alcohol, lanolin alcohol) in the first three or four ingredients.
Watch out for:
- Body washes and lotions. Many common brands contain alcohol compounds, including products from Dove, Eucerin, Aveeno, Vaseline, and Cetaphil.
- Hair gels, oils, and strong-hold styling products.
- Moisturizing shampoos and conditioners.
- Facial cleansers and toners. Some products labeled “alcohol-free” still contain alcohol compounds that trigger the sensor.
- Near-beer, kombucha, and anything marketed as a non-alcoholic beverage. Many contain trace ethanol.
Ingested products are trickier. Mouthwash, cough syrup, and cold medicines that contain ethanol can register the same as drinking if you take enough of them. The manufacturer says these products are acceptable as long as you don’t consume enough alcohol to become intoxicated.3SCRAM Systems. Permitted Products for SCRAM CAM Switch to alcohol-free versions whenever you can. Getting flagged for NyQuil is avoidable.
The sensor only reads what reaches it. A problematic lotion on your hands won’t trigger the bracelet, but the same lotion rubbed on your legs could.
Rules You Have to Follow Every Day
The bracelet must stay in direct contact with your skin at all times. No socks, bandages, or anything else between the sensor and your leg. Any barrier registers as a tamper event and gets reported.4SCRAM Systems. County Repeat Offender Program Guide An infrared sensor constantly watches for anything placed under the device, so there’s no slipping something underneath without being caught.
Clean around and under the bracelet daily with mild soap and water, rinse thoroughly, and dry.5SCRAM Systems. Health and Safety Notice for SCRAM Systems Products Hygiene affects both accuracy and your comfort. Neglecting it is the fastest route to painful skin irritation.
Showering is fine, but you cannot submerge the bracelet in a pool, hot tub, lake, or bathtub.4SCRAM Systems. County Repeat Offender Program Guide Water damage to the internal components can corrupt your data and leave you on the hook for replacement equipment.
A base station at your home receives the data the bracelet collects and transmits it to the monitoring company. Keep the base station plugged in. If you wear a SCRAM GPS unit, charge it daily until you see a solid green light.6SCRAM Systems. Frequently Asked Questions Unexplained gaps in your record raise suspicion even when the cause is nothing worse than a dead battery.
Skin Problems and Medical Emergencies
Common issues include redness, irritation, sores, bruising, and open wounds.5SCRAM Systems. Health and Safety Notice for SCRAM Systems Products Inspect the skin under the bracelet daily and contact your supervising authority immediately if any of this develops. A documented medical request to reposition the device is very different from an unexplained tamper alert.
The bracelet is not compatible with MRI machines and may interfere with other equipment that produces magnetic fields. Tell technicians about the device before any imaging. In a medical emergency, anyone can cut the strap and remove the bracelet. The manufacturer’s guidance is unambiguous: remove first, then contact your supervising authority as fast as possible with hospital documentation.5SCRAM Systems.

What a Violation Looks Like
The monitoring company flags a reading as a confirmed drinking event once it surpasses a TAC equivalent to roughly 0.02 BAC. What follows depends on your jurisdiction, your supervising agency, and the terms of your court order. The usual pattern is progressive sanctions: a first violation often triggers a warning and a show-cause hearing, with repeated violations escalating toward revocation of bond or probation and possible jail time.7SCRAM Systems. SCRAM Continuous Alcohol Monitoring Frequently Asked Questions
Tamper events are reported separately. Some agencies treat them as seriously as drinking violations; others allow more leeway.7SCRAM Systems. SCRAM Continuous Alcohol Monitoring Frequently Asked Questions
You can challenge a reading. The prosecution generally needs to prove the violation by a preponderance of the evidence. A defense can argue malfunction, calibration issues, or that the TAC curve doesn’t look like alcohol consumption. Real drinking produces a smooth, continuous curve; equipment problems and environmental interference tend to produce jagged, sawtooth patterns. Independent evidence helps too. If an ignition interlock device registered zero BAC at the same time the bracelet flagged a positive reading, that contradiction carries weight.
What It Costs
You pay for your own monitoring. Expect two charges:
- A one-time installation fee when the bracelet is fitted, typically $50 to $100 or more depending on the vendor and jurisdiction.
- A daily monitoring fee covering data transmission, analyst review, and reporting, generally $5 to $15 per day.
Across a 90-day period at the middle of that range, daily fees alone run roughly $900 to $1,350, on top of fines, attorney costs, and other court-related expenses. Some jurisdictions offer reductions or waivers based on income or participation in government assistance programs. If you’re going to struggle to pay, raise it with your attorney or probation officer early, because missed payments can themselves become a compliance problem.
How Long You’ll Wear It
Court-ordered monitoring periods range from as short as two weeks to as long as ten years, depending on the offense. A common requirement is 90 consecutive days of compliance, meaning no drinking events and no tamper violations in that window.7SCRAM Systems. SCRAM Continuous Alcohol Monitoring Frequently Asked Questions A violation during the monitoring period may reset the clock and extend your time on the device.
Only an authorized technician can remove the bracelet when your monitoring ends. Do not try to cut it off yourself, even on your last scheduled day. That registers as a tamper event and can create fresh legal problems at the finish line.
Traveling While Monitored
Get written approval before booking any trip. Traveling without permission can be treated as a program violation regardless of whether your readings stay clean. If you’re approved, carry documentation showing you’re enrolled in a SCRAM program. At airport security, tell the TSA agent you’re wearing an electronic monitoring device that cannot be removed. The agent may swab the bracelet and pat down the area, but you should be allowed through while wearing it.6SCRAM Systems. Frequently Asked Questions
The practical headache with travel is data upload. Your base station stays at home, so the bracelet stores readings while you’re gone. An extended trip without uploading leaves an unexplained gap in your record. Coordinate with your monitoring agency before leaving if you’ll be away more than a day or two so an alternative upload method can be arranged.
