The AIRMAR SensorCheck™ App, paired with the TDT1000 Transducer Diagnostic Tester, compares the performance of a transducer in the field to its original AIRMAR factory specifications. Simply install the SensorCheck™ app on your Bluetooth LE-enabled smart device, connect to the TDT1000, and get started! Accurately test both traditional and CHIRP-ready transducers that operate at frequencies ranging from 10 kHz to 500 kHz. With CHIRP-ready models and any traditional models 1kW and above, the TDT1000 will automatically read XducerID® features, such as transducer model, frequency, part number, serial number, total run time, and maximum internal ceramic temperature. When the test is complete, an IN RANGE or OUT OF RANGE determination is made and test reports are automatically generated. Results can be emailed or texted directly to the boat owner or an AIRMAR technician. SensorCheck™ enables technicians to automatically submit warranty information to AIRMAR. The TDT1000 kit includes test unit, TDT Test block, power supply, break-out box for bare wire transducers and carrying case. Additional OEM Test Cables required (sold separately).

Verdict
The clearest difference is rating: SensorCheck™ at 3.8 against Helmsman's 2.0. Helmsman's advantage is update cadence (fortnightly vs every 3 months) and review sentiment (22% vs 0%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SensorCheck™ holds the better App Store score, 3.8 against 2.0. Both are backed by a comparable volume of ratings — 7 and 6 respectively.
