Technical tools for Raymarine service and upgrade work
Working tools built on manufacturer data and the live HME catalogue: an interactive Type 1 linear drive parts diagram, an MFD upgrade planner, and a bidirectional transducer compatibility tool. All run entirely from data shipped with the app.

Drive service
Type 1 linear drive parts diagram

Transducer compatibility
Plotter ↔ transducer tool

How these are built
Draft demo. Everything on these tools comes from data checked into the repo, so the pages render without calling Drive, Raymarine or the shop at request time.
- Verified parts only
- 10 Type 1 spares read from live HME product pages. Parts with no standalone listing say "contact HME" rather than linking somewhere wrong.
- Manufacturer tables
- 33 upgrade targets and 207 transducers from Raymarine compatibility tables, shipped with the bundle.
- Honest about gaps
- Plotter compatibility is family-level from the manufacturer table. Where a fitment is unconfirmed, the UI says so instead of guessing.
