Once the stems are fully assembled, attach the control box to the upper stem.
Extend the adjustable S-shaped rod to a comfortable length between 47.8 and 59.4 inches.
Finally, insert two 9-volt batteries into the control box compartment.
Each step builds on the previous one, so don’t skip ahead.
A properly assembled unit guarantees accurate detection performance and protects the device’s structural integrity during use.
How to Insert Batteries and Power On the RM Rico Max
Once the RM Rico Max is fully assembled, you’ll need to insert two 9-volt batteries into the designated compartment within the control box.
Follow proper battery safety practices by checking polarity alignment before securing the compartment cover. Avoid mixing old and new batteries, as mismatched power sources reduce performance and risk leakage damage.
After inserting the batteries, press the power button and wait approximately 5 seconds for start-up calibration to complete. During this window, the detector initializes internal settings and confirms coil compatibility between the control box and your connected 10-inch waterproof search coil.
Don’t interrupt this process.
Once calibration finishes, the back-lit LCD screen activates, displaying target recognition, depth, and sensitivity data. You’re now ready to select an operational mode and begin detecting.
Which Detection Mode Should You Use?
With the detector powered on and calibrated, your next step is choosing the right detection mode for your environment and target type. The RM Rico Max offers five modes, each optimized for specific metal detecting scenarios.
After coil calibration, selecting the correct mode directly impacts detection accuracy.
- All Metal – detects every metallic object without filtering
- DISC (Discrimination) – filters unwanted metals using a three-tone audio system
- MEMORY – recalls your last detected target’s settings automatically
- JEWELRY – optimized specifically for gold and precious metal targets
- PINPOINTER – narrows the exact location of a confirmed target
Match your mode to your environment. Trashy sites benefit from DISC mode, while open fields allow All Metal scanning for maximum coverage and target variety.
How to Sweep the Coil for Full Ground Coverage
Sweeping the coil correctly determines how much ground you actually cover and how many targets you find. Move the coil side-to-side in a steady arc, maintaining a sweep speed of 2 to 3 seconds from right-to-left-to-right.
Keep the coil between 5cm and 10cm above the ground throughout each pass. Overlap each previous sweep slightly so you don’t leave gaps in your coverage.
Never stop moving the coil mid-sweep, since a stationary coil won’t detect anything. Walk forward at a consistent pace to keep your scanning pattern tight and uniform.
Practicing good coil maintenance by avoiding hard surface contact protects your seals and extends detector life. After long sessions, prioritize battery replacement to make sure you’re always operating at full sensitivity and detection depth.
What Every Icon on the RM Rico Max LCD Screen Means
The backlit LCD screen on the RM Rico Max gives you real-time feedback on four key readings: metal target type, target depth, recognition level, and sensitivity level. Each icon delivers critical data during metal detecting so you’re never guessing. After coil calibration, the display updates dynamically with every sweep.
Here’s what each screen element tells you:
- Metal target icon – identifies the detected material category
- Depth indicator – shows estimated burial depth of the target
- Recognition level – displays discrimination data to separate iron, gold, and bronze/nickels
- Sensitivity bars – reflects your current sensitivity setting across three levels
- PINPOINT symbol – activates when you press and hold the PINPOINT button during target narrowing
Read these icons together for precise, confident target identification every time.
How to Set Sensitivity and Depth on the RM Rico Max
The RM Rico Max gives you three sensitivity levels to choose from, letting you fine-tune detection performance based on target size and local electrical interference.
If you’re picking up false signals or noise, drop the sensitivity level to stabilize the detector’s response.
Once you’ve locked onto a target, check the LCD display to read the estimated depth of the detected target icon, giving you a precise excavation starting point.
Adjusting Sensitivity Levels
Adjusting sensitivity on the RM Rico Max directly affects how accurately you detect targets at varying depths, so getting this setting right is crucial. The detector offers three sensitivity levels, letting you calibrate detection power based on terrain and target size.
Sensitivity adjustment becomes critical when interference disrupts your scanning.
Use these guidelines for effective false signal reduction:
- Start at the highest sensitivity level for maximum depth detection
- Lower sensitivity if electrical interference causes false signals or noise
- Match sensitivity to your target size for precise identification
- Monitor the LCD display to confirm your current sensitivity level
- Reduce sensitivity near power lines or urban environments
Cycling through levels systematically ensures you’re always operating at the best setting for your specific environment without sacrificing detection accuracy.
Reading Depth Display
Once you’ve dialed in your sensitivity level, reading the depth display gives you the next layer of target information. The backlit LCD screen shows an estimated depth icon for each detected target, letting you gauge how deep you’ll need to dig before breaking ground.
Keep in mind that mineral interference in heavily mineralized soil can skew depth readings, making targets appear shallower or deeper than they actually are. If readings seem inconsistent, adjust your ground balance and recheck.
Also monitor your battery life during extended sessions — weak batteries reduce processing accuracy, which directly affects depth estimation reliability. With fresh batteries and proper ground calibration, the depth display becomes a dependable tool that helps you prioritize targets and manage your time efficiently in the field.
How to Ground Balance the RM Rico Max
Ground balancing the RM Rico Max helps eliminate false signals caused by naturally occurring minerals in the soil. Proper coil calibration ensures accurate target identification and cleaner audio response. Follow these grounding techniques:
- Lower the search coil to roughly 5cm–8cm above the ground for standard scanning.
- If sound increases as you lower the coil, raise it to approximately 50cm.
- Press and hold the ground balance button while holding the coil at 50cm.
- Allow the detector to recalibrate before resuming your sweep.
- Reduce sensitivity if electrical interference continues causing false signals after balancing.
Once balanced, you’ll notice considerably fewer ghost signals and more reliable depth readings. Repeat this process whenever you move to a new area with different soil composition.
How to Pinpoint a Target With the RM Rico Max
To pinpoint a target with the RM Rico Max, sweep the coil slowly until you’ve identified the position that produces the loudest audio signal.
Step to the side of the target and rotate the search coil to narrow the detection area further.
Then press and hold the PINPOINT button to activate the sensitivity indicator bars.
Move the coil incrementally toward the signal source as the sound volume increases.
Locating the Loudest Signal
When you’re ready to pinpoint a target with the RM Rico Max, start by sweeping the coil slowly over the detection area and listening for the loudest audio signal. The peak sound indicates the target’s center position. Proper coil calibration and minimizing ground interference are critical for accurate results.
Focus on these steps to isolate the loudest signal:
- Sweep in slow, controlled arcs from right to left
- Note the exact position where audio volume peaks
- Avoid ground interference by maintaining 5cm–8cm coil height
- Recheck coil calibration if signals sound inconsistent or erratic
- Mark the loudest signal point mentally before rotating your approach angle
Once you’ve identified the peak signal location, you’re ready to narrow the target zone further using the PINPOINT button.
Rotating the Search Coil
After marking the loudest signal point, you’ll need to rotate the search coil to narrow the target’s exact location. Step to the side of the detected target, repositioning your body to change the coil orientation relative to the buried object. This perpendicular repositioning cross-references the signal, eliminating misleading readings caused by coil shape or sweep angle.
As you rotate, sweep slowly across the same area from your new position. The intersection of both sweep directions reveals the target’s precise location.
Keep the coil between 5cm and 10cm above ground during this process to maintain accuracy and practice proper search coil maintenance by avoiding contact with rocks or hard surfaces. Consistent coil height ensures reliable signal readings throughout the pinpointing procedure.
Using the Pinpoint Button
Once you’ve identified the target’s cross-referenced location, press and hold the PINPOINT button on the control box to activate the pinpointing mode. The LCD display will show the pinpoint symbol alongside sensitivity indicator bars. To minimize ground interference, verify proper coil calibration before narrowing your search.
Follow these steps to zero in on your target:
- Hold the PINPOINT button firmly until the symbol appears on screen
- Move the coil incrementally toward the strongest signal source
- Listen for increasing audio volume as you approach the target
- Adjust sensitivity if ground interference disrupts the signal reading
- Repeat directional passes until the loudest point is confirmed
The loudest audio signal marks your target’s precise location. Work methodically, keeping movements small and deliberate for accurate results.
How to Clean and Store Your RM Rico Max After Use
Proper care after each use keeps the RM Rico Max performing reliably and extends its lifespan. Follow these cleaning tips to maintain excellent condition: wipe the LCD screen and coil surface with a soft cloth, avoiding abrasive materials that scratch or degrade the waterproof seal.
Don’t drag the coil across hard surfaces, since impacts compromise the IP68 waterproof integrity. If you’ve used the detector in wet conditions, dry all surfaces thoroughly before storage.
For effective storage solutions, keep the unit in a dry, controlled environment away from moisture and extreme temperatures. Remove both 9-volt batteries if you won’t use the detector for an extended period, preventing corrosive leakage inside the control box.
These straightforward steps protect your investment and ensure the RM Rico Max is ready for your next search.
