About Seiche
Freshwater spearfishing rooted in Grand Haven.
Seiche is a Grand Haven, Michigan–based spearfishing shop and education resource built specifically for the Great Lakes and the people who dive them.
Grand Haven, Michigan
Why we exist
A freshwater-first shop for a different kind of diving.
Most spearfishing resources were built around saltwater. Seiche was created to serve freshwater divers with gear, education, and practical guidance shaped by Great Lakes conditions.
We believe access begins with trustworthy information: what is legal, how to identify species, how to dive responsibly, and how to care for the fish you harvest.

Lake Michigan • West Michigan
Our home water
Based in Grand Haven. Built for the Great Lakes.
Grand Haven sits where the Grand River meets Lake Michigan. It gives Seiche a real connection to the water, weather, seasons, and communities that define freshwater spearfishing in this region.
We are building Seiche as both an online destination for Great Lakes divers and a local West Michigan resource. Our goal is to help more people enter the sport safely, find the right equipment, understand local regulations, and become better stewards of the places they dive.
