PAPS Digital Gauge Module

The PAPS Digital Gauge Module is an optional accessory for the PAPS designed to provide accurate and reliable spine deflection readings.  Use the zero reference support for even finer measurements.  Now, you can confidently identify which of your arrows have similar deflection values.

1. Mounting Arm: Made of CNC machined aluminum, it is securely mounted on the tower with two mounting screws equipped with O-ring retainers. A stainless tightening nut mounts The digital gauge on the arm.
2. Digital Gauge: Inserted by the gauge tip through the top of the tower, it can measure the deflection of your arrow quickly and reliably. It is equipped with a large, easy-to-read LCD display, and the reading can be set to “hold / memory / zero.” Modes include inch (e.g., 0.0005”), metric (e.g., 0.1mm), and fraction (e.g., 1/64”). The 40mm plunger is made of GR5 Titanium for accurate measurement. Long-lasting standard 3V CR2032 batteries power the meter, which will auto-shut off after five minutes of inactive operation.
3. Zero Reference Support: This accessory provides a reliable zero reference point before measurement. Made of CNC machined aluminum, as its name suggests, this device is to be placed beneath your shaft to support it so it becomes parallel to the support rollers for zeroing the digital gauge.
4. Brass Weight: The brass weight is machined to provide constant weight to act on your shaft, thus allowing you to measure the deflection (stiffness) of different shafts. With the brass weight installed, the system resembles 1.92lb (880g) of total pressure when suspended from the center of a 28-inch (0.71-m) arrow shaft, as is the standard method for such measurements via the American Society for Testing and Materials (ASTM) F203105.

Note: For all pre-2019 PAPS owners who want to add a digital Gauge, you may have to send your older PAPS tower to fit our newer version DG. We no longer have the older version of the digital gauge to fit the older version of the tower, so it may have to be an update for you.
