Frequently Asked Questions

How do I recharge inserts on a boat without a freezer?

Pack your spare inserts in a quality marine cooler with ice or ice packs before heading out. A well-insulated cooler will keep backups frozen for 6-8 hours, which is enough for a full day on the water. Some anglers dedicate a small soft cooler just for their inserts.

Will saltwater damage the insert?

The insert is fully sealed and waterproof, so incidental contact with saltwater will not damage it. Simply rinse with fresh water after use to prevent salt residue buildup. The materials are designed for outdoor use in harsh conditions.

Does it fit under a wide-brim fishing hat?

Yes, the insert is designed to work with virtually any hat style including wide-brim sun hats, bucket hats, and standard baseball caps. The thin profile means it conforms to the crown of the hat without changing the fit or feel.

How long does cooling last in direct sun on water?

In direct sun with water reflection intensifying heat, expect 15-25 minutes of active cooling per insert. The reflection off the water does increase ambient temperature around your head, so bringing 3-4 spare inserts in a cooler is recommended for a full day of fishing.
