Verify throwing implements quickly and accurately with the Blazer Digital Implement Scale. With a 55 lb capacity and a clear digital readout, it lets officials and coaches weigh shots, discs, hammers, and weights at the certification table — a compact, dependable tool for keeping every implement within spec.

Key features & specs:

A practical certification tool for meet officials and throws coaches who need to confirm implement weights on site. Place the scale on a flat, stable surface, zero it before weighing, and use the detachable display for an easy read. Remove the batteries during long off-season storage, keep the scale clean and dry, and store it in your certification kit so it's ready for every meet.

• The patent-pending "thumb-up" grip ensures less wrist strain and superior control.

• Dust, dirt and other particles can disrupt a light beam used in competitive units. Our magnetic pick-up avoids these problems.

• Designed to NEMA Class II standards, the counter housing ensures that it will not be damaged by rain. You can safely clean the entire wheel with a damp cloth.

• The easy-to-read digital counter is in the most protected spot on the wheel. With the handle up, it is nearly impossible for the counter to come into contact with the ground. With the handle down, the roll bar offers solid protection. Counter requires 2 AA batteries (not included).

Certifying hammers at check-in has always meant kneeling on the ground with a vertical gauge — the Gill Hammer Length Gauge ends that. Its horizontal design lets officials measure hammer length at a comfortable working height, speeding up weigh-in and taking the strain off backs and knees during long meets. Every hammer gets verified quickly and accurately, so your competition stays on schedule and on spec.

Key features & specs:

• Aluminum gauge constructed horizontally for ergonomic use — no bending to the ground
• Toggle Clamp pulls and straightens the wire to capture true overall length
• Hammer Read-Out Tool precisely captures the measured length
• 3-piece unit breaks down for convenient transport and storage
• Built for repeated use at the certification table throughout a meet

A must-have for meet officials and throws coaches certifying hammers at sanctioned competitions. Store the three sections together in your certification kit, keep the clamp and read-out mechanism clean and free of grit, and check calibration at the start of each season so your measurements stay reliable.

Running a compliant indoor throws competition means every implement has to be verified before it flies, and the Gill NCAA Indoor Implement Certification Kit puts everything officials need to do that job in one self-contained package.

Indoor weight throw implements have to fall within strict length limits, and the Gill Indoor Throwing Weight Gauge lets officials and coaches verify that dimension quickly and confidently at check-in. Instead of eyeballing a suspect implement or holding up the event, you get a purpose-built gauge that confirms the overall length of each indoor weight meets specification in seconds.

Key features & specs:

• Purpose-designed to check the overall length of indoor weight throw implements
• Adjustable knob for quick calibration before each use, ensuring consistent, accurate readings
• Built for repeated use at the certification table throughout a meet

For meet directors and throws officials running indoor competitions, this gauge is a key part of keeping weigh-ins fair, fast, and compliant. Recalibrate with the adjustable knob at the start of each session, and store the gauge indoors in your certification kit, clean and dry, to preserve its accuracy season after season.

Weighing round throwing implements on a flat scale platform is a balancing act — literally. The Gill Scale Ring (3D Printed) solves that problem with a simple, precision-made ring that cradles shots and weights on the scale so they sit still while officials record the reading. No more chasing a rolling shot put across the check-in table or second-guessing an unsteady weigh-in.

Key features & specs:

• Purpose-built ring keeps round implements steady and centered on the scale during weigh-in
• 3D-printed for a consistent, repeatable fit
• Lightweight and easy to place on or remove from the scale platform
• Pairs with Gill implement scales for faster, more reliable certification

A small but valuable accessory for meet officials and throws coaches who want quick, accurate weigh-ins without fumbling with unstable implements. Store it with your certification kit so it's always on hand at check-in, and wipe it clean of chalk and grit to keep implements seating flush on the ring.

Accurate weigh-ins are non-negotiable at a sanctioned meet, and the Gill Essentials Implement Scale gives officials a compact, dependable digital scale for certifying shots, discs, hammers, and weights on site.
