Jeff Zack

Jeff Zack has spent years fishing for salmon and refining jigging techniques around Muskegon, Ludington, and the Gulf of America. After wishing he could fish another line without adding another aching arm, he began building his own jig fishing machines. The early versions were fussy, but they caught fish. Five years of field testing later, those experiments have evolved into the all-digital Relentless JFM, designed to make jigging more effective and enjoyable.

Jeff is a lifelong entrepreneur and inventor. A Chamber Entrepreneur of Excellence recipient, he has helped build three successful start-ups. Most recently, he co-founded and co-owned Fomcore before retiring in 2024. Retirement gave him more time to fish, but it did not quiet the entrepreneurial instinct. Relentless JFM brings those two passions together.

FREQUENTLY ASKED QUESTIONS

What do I do if I don't have an Android Phone or Tablet?

First, the Relentless JFM still catches fish in manual mode. But second, I think I have found an excellent solution that only cost $59.00. Check out the Boost Mobile TCL 50XL Phone with NEXPAPER screen that is easy to read, even in bright sun and with sunglasses on! I like it so much I am switching from my phone to this. You can see it at Walmart. Check it out on Videos Page.

How much will it cost?

It is $700 for the base unit, $759 with battery and charger.

When will it be available?

Production is underway and first units will be available September 1, 2026

What kind of battery do you use?

The RFM uses Kobalt style 24V, 4AH, batteries that provide between 4 and 6 hours of continuous use. We offer a generic 4AH, 24V battery and charger for purchase with the RFM but do not offer additional batteries. Your best source for additional batteries is Lowe's where they are often on DEEP discount. Alternate is Amazon.

Will it work in saltwater?

Yes, but it has not been extensively tested in a saltwater environment. Many of the components are made of aluminum and care should be taken concerning corrosion. The motor, servo, and cables are IP65 rated for gentle washdown. The enclosure is as water resistant as we can make it but additional care should be used.
