NT301 vs NT624 vs NT809BT — Which SEAFLO Scanner?
Three of the most common upgrade paths: budget engine scanner (NT301), full-system DIY tool (NT624), and bi-directional pro unit (NT809BT). Here is how they differ and who each one fits.
1 SEAFLO NT301 — engine-focused
Check engine codes, live data graphs, smog readiness, and battery voltage. Does not scan ABS, SRS, or transmission on most vehicles. Best for drivers who only need powertrain diagnostics.
2 SEAFLO NT624 Elite — all-system DIY
Adds ABS, airbag, and transmission modules plus eight maintenance resets. Bi-directional tests on supported models but less depth than NT809BT. Best for home mechanics doing brakes and full-system scans.
3 SEAFLO NT809BT — bi-directional pro
Thousands of active tests, Bluetooth, ECU coding where supported, and flagship-level coverage. Best when you command actuators regularly or run a small shop.
