About Us

Stevens Instrument Company began as Stevens Experimental over 50 years ago, producing some of the earliest coil testers, magnet chargers, and other marine-specific service aids.

The company was purchased by the present owners/operators in 1971 and is now a third-generation family-owned and operated business.

We prioritize longevity, both in our products and in customer relations. We thank the thousands of loyal customers who have relied on us since our inception, and are eager to demonstrate to newcomers the reasons for such loyalty.
