Alternatives
$33.99 · 79 / 100B+
Accurate to within a degree, recalibratable, and with the longest reliability record in the hobby — the default freshwater pick.
$53.99 · 81 / 100B+
A titanium element paired with an external digital controller — precise, shatterproof, and the most features per dollar here.
