How it differs from its neighbors

Nokta keeps the Simplex+ page online under its discontinued products and names no replacement. The Simplex Ultra also uses an 11-inch round DD coil, the SX28, and moves to 15 kHz, rated IP68 to 16 ft (5 m). It weighs 2.6 lb.

The Simplex Lite shares that frequency and rating with a smaller 9.5 x 6-inch SX24 coil. Both current models list sensitivity in 30 levels, against 6 levels on the Simplex+.

For more than one frequency, Nokta's Score runs Multi, or single 15 kHz at 2.6 lb. Nokta's warranty was 2 years on the Simplex+. It is 3 years on the Lite and Ultra.
