A Simple Tool Reshape Metal Detector Armrest Cup Width: A Step-by-Step Guide

Updated: Jul 3, 2023

Metal detector enthusiasts often find themselves in situations where the armrest cup width of their metal detector needs to be adjusted for a more comfortable fit. In this blog, we will introduce a simple and effective method using a hair dryer to reshape the metal detector armrest cup width. This technique can provide a customized fit, ensuring a pleasant and ergonomic experience during metal detecting sessions.

1. Gather Your Materials:

Before you begin, make sure you have the following materials ready:

- Hair dryer

- Metal detector with an adjustable armrest cup

- Protective gloves (optional)

- Towel or cloth

2. Heat the Armrest Cup:

Start by plugging in your hair dryer and setting it to a medium heat setting. Hold the hair dryer at a safe distance from the armrest cup to avoid overheating. Slowly move the hair dryer back and forth across the armrest cup, evenly distributing the heat. Ensure that the entire surface of the cup receives heat for effective reshaping.

3. Test and Adjust:

Once the armrest cup feels warm to the touch, put on protective gloves (if desired) and carefully place your hand inside the cup. Gently press and mold the cup to the desired width. Remember to apply moderate pressure and make small adjustments at a time to prevent overstretching or damaging the armrest cup.

4. Cool Down:

After reshaping the armrest cup, turn off the hair dryer and allow the cup to cool down naturally. You can speed up the cooling process by placing a towel or cloth over the cup to absorb excess heat. Avoid touching the cup until it has completely cooled down to prevent burns or distortions.

5. Test the Fit:

Once the armrest cup has cooled down, test the fit by wearing the metal detector and adjusting the straps to your preference. Ensure that the cup sits comfortably on your arm and provides adequate support. If further adjustments are required, repeat the process from step 2.


Reshaping the cup width of a metal detector armrest using a hair dryer is a practical and cost-effective method. By following the steps outlined in this blog, you can achieve a customized fit that enhances your comfort and overall metal-detecting experience. Remember to exercise caution and patience throughout the process to avoid any damage to the armrest or the metal detector itself. Happy metal detecting!
