OnX Fish, as it’s called, has been free to anglers since it went live in April. The new fishing platform is modeled after onX Hunt, an industry leader in the digital mapping industry. Developers are still in the “feedback-gathering stage,” said Joel Nelson, senior regional vertical marketing manager for onX. A fishing pro and outdoors enthusiast from Cannon Falls, Minnesota. Nelson has a 25-year background in GIS (Geographic Information System) technology and joined onX in April.
