Archery Plungers

Recently I've ordered 2 Infitec Nexus plungers for friends. The moment I touched it, I regretted.. The plunger pin does not go in and out smoothly. Feels like sandpaper.. And it costs S$35. Even Cartel plungers which cost way less feel smoother than that.

Today I would like to share about the Fivics SM740 vs Beiter Plunger.

Similarities
Both these plungers are very similar in the sense they allow micro-tuning and adjustments of the plunger tension. They are both about the same lengths.
Both are extremely smooth when using.
The concepts for both are the same for securing onto the riser and for micro tuning.




+ SM740
Just 1 tool required to tune. The blue spanner and the small allen key attached to it. Beiter requires a couple more tools like the screw driver.
The micro-tuning adjustment is independent adjustment from the body of the entire plunger. (when turning micro adjustment, entire body does not turn). Essentially, it pushes a platform at the back of the plunger forward or backward. The adjustment level can be seen through a window at the side of the plunger. Beiter works in a similar manner, except that the entire body turns.

+ Beiter
Very inter-changeable and easily available parts. Multiple plunger pin lengths to suit your riser and shooting needs. SM740 spare parts do not come easily but other than the plunger pin, some parts can be inter-used.
The spring is actually really good, compared to the SM740 spring. The SM740 spring increases tension exponentially upon being depressed.
The sheer number of Olympians can attest to the goodness of this plunger. Most likely because there is zero or extremely low tolerance in the plunger pin movement. It only moves in and out, and no left/ right around the opening.

+ SM540
Similar to SM740, just 1 tool required. Same method of attaching onto the riser
The adjustment method is similar to Beiter. The whole body of the plunger turns.
(but I still prefer to use the beiter spring in the plunger)


Price (in SGD)
Fivics: 80+
Beiter: 160+

What do I do..?
I am using the SM740 (or 540) because I like the way it can be micro-tuned and the gauge can be seen through the window.
I dislike the Fivics spring because the tension increases wayyy to much upon being pushed down.
Use the SM740 plunger with the Beiter spring. :)

Thankfully the springs are of the same size and quite interchangeable.
Plunger pins are not
Grub screws are the same
Spanners are not of the same size
