In its stock form, the EagleTac M2/M2X uses the controller ring on the bezel to smoothly switch between the following modes: Off > Low > Med > High > Turbo > Strobe. Additionally, the stock tailcap can be swapped out for the M25 module to add a click switch to the either the M2 or M2X. With the click switch the user often does not require that the bezel have an “off” position. Also, some users do not need the strobe and accidentally trigger it while trying to switch the light to turbo output. This article will show you how to disable both the “off” and “strobe” features using commonly available items. The modification should take less than 5 minutes to complete!

Note: Pinnacle Flashlights is not responsible for personal injuries or damages caused to your EagleTac M2/M2X while attempting to perform this modification.

Step 1: You will need the following items:    - EagleTac M2/M2X    - Masking Tape    - Scissors    - Super Glue    - Paper Clip    - Old Hotel/Credit Card
Step 2: Orient the M2/M2X so that the tailcap is towards you and the bezel is facing away. Place a piece of the masking tape around the bezel right above the selector ring. The tailcap should be clicked “on” and the bezel rotated all the way to your “left” in the “off” position. Mark on the tape the position of the left edge of the large tab. Now, rotate the ring to the “right” until the light turns on “low”. Again, mark on the tape the position of the left edge of the tab. The tape will have 2 markings like the image to the right.
Step 3: Rotate the ring completely to the “right” so that it is in “strobe”. Mark on the tape the position of the left edge of the same tab used in Step 2. Rotate the ring to the “left” until the light switches to “turbo”. Again, mark on the tape the position of the left edge of the tab. Your tape should have 2 additional markings like the image to the right.
Step 4: At this point, the tape should have 4 markings. Note that they may or may not be equal.
Step 5: Remove the bezel. Remove the selector ring by gently pulling it over the threaded end of the bezel. Observe the slot in the bezel where the selector ring stops.
Step 6: Observe the slot in the bezel on the other side where the selector ring stops. Clean the grease off of both of these areas with a cotton swab or tissue.
Step 7: Cut a sliver of the credit card about the width of the notch in the bezel. Then cut 2 pieces which will be the lengths of the 2 measurements made on the tape.
Step 8: The 2 plastic pieces can be slightly bent to better fit the curvature of the bezel
Step 9: Test fit the pieces. Note that the piece for the “off to low” goes on the “left” side of the slot and the piece for the “strobe to turbo” goes on the right side. Place a small strip of super glue on the bezel and carefully place the plastic pieces in their appropriate locations. Press them down firmly with a paper clip and remove any excess glue.
Step 10: Give the glue sufficient time to set and dry. The finished product should look like the image to the right. Replace the selector ring and reattach the bezel to the body!

So how well does this modification work? Check out the video below!

This video demonstrates the ability of the Nitecore EX10 LED flashlight to operate while submerged in approximately 10 feet of water.

The Nitecore EX10 is a state of the art LED flashlight with quite possibly the world’s most advanced user interface. It is extremely small in size and weight and is suitable for every day carry. It features an infinitely variable digitally-controlled circuit to regulate light output. The latest R2 version runs off of a single 123A lithium battery and has a maximum output of 145 lumens. The body is constructed of 7075 military-grade aluminum and is finished with an exceptionally durable Type III hard anodized finish.

Below is a video of the underwater demonstration:

The Nitecore Piston Drive (PD) System available in the D10, D20, and EX10 is among the most advanced flashlight “operating systems” in the world. With an infinitely adjustable output, you can program the exact amount of light or runtime that you need making it a perfect choice for daily carry. The system is very easy to use, but may be confusing at first. This article will explain how to use all the features of this amazing user interface.

Light Operation: The light can be operated through one of three switching options available.
1) It can be operated by simply twisting the bezel clockwise to switch on and counterclockwise to switch off. This is the most straight forward operation.
2) When light is in twist mode off position, pushing the tailcap activates momentary mode.
3) When the head is fully tightened, the light enters tailcap switching mode. In this mode, light behaves as simple click switch light. Push the tailcap to switch on and push again to switch off.

Changing Brightness: When light is operating in tailcap switching mode, from ON position, press and hold piston will start ramping up or down brightness level. When desired light level is achieved, simply release the piston. The light will remember the last used brightness level.

Instant Minimum & Maximum: When light is operating in normal switching mode, from ON position, double clicking the tailcap jumps to minimum light output level. Also, from ON position, double click & hold will instantly switch light to maximum output level.
