Closing Season Mode in SplashLens helps pool and spa pros document winterizing proof before freeze season. In one mobile workflow, techs can capture chemistry, water level, equipment-pad photos, drain-plug proof, cover condition, heater/salt/robot notes, declined work and callback-risk items. The result is a cleaner record for homeowners, senior techs, builders, warranty/support teams, and spring reopen reviews. SplashLens is a field reference and proof tool; it does not replace manuals, labels, local code, company procedures, or qualified judgment.
