These products require a full fixed price repair to resolve their issues.

What is included in a Full, Fixed-Price Repair?

  • Perform detailed visual, audio and functional check for damage or problems.
  • Test Bluetooth communication (if Bluetooth / LiNK model) 
  • Replace damaged case, can, handle, cone or other parts if needed. EmPower Oarlock only – replace plastic oarlock assembly.
  • Update firmware to latest version, if applicable.
  • Leak test and repair minor leaks.
  • Clean window and all connectors, lubricate connectors.
  • Install new lanyard and float if needed.
  • Install new Bumpers if ordered (a great way to freshen the appearance of your CoxBox or Megaphone!)
  • Test battery charge/discharge and power. Replace battery if needed.*

*The cost of a new internal battery pack is included in the fixed price repair for “metal can” CoxBox models. Evaluation of one removable battery pack is also included in the fixed price repair of your CoxBox 08 or Blue Ocean Megaphone, so we recommend returning your battery WITH your unit for evaluation. However, a new battery pack, if required, will be billed separately.

These products are either no longer in production, or are constructed in such a way that we cannot perform a full overhaul as described above. For these products, if desired, we will conduct an evaluation to determine if your problem can be fixed with a minor repair, such as a battery compartment fix or code upgrade. If this is not possible, most are eligible for Trade-In Trade-Up and the $25 SpeedCoach Gold/Red/StrokeCoach/Interval Repair will be credited to your Trade-Up Order. If the product is not repairable and you decide to discard it, the $25 fee will not be refunded or credited to a future order.

Battery Packs: If you wish to have us test an out-of-warranty battery pack separately from a CoxBox 08 or Megaphone, select $25 CoxBox Battery option. The $25 fee will be credited to the price of a replacement battery pack if purchased, or retained if the pack is returned to you or discarded after test.

Shell Wiring: CoxBox, SpeedCoach and StrokeCoach shell wiring is generally not repairable. Of course, all are covered under warranty as indicated by the date code so please do return shell wiring for warranty replacement if it is less than two years old and not working correctly. If you wish to have us evaluate shell wiring, please select the $25 Shell Wirting option. This evaluation fee will be credited to the price of replacement wiring (same or comparable) if you decide to replace it.

Loudspeakers: Speakers are permanently sealed and not repairable. Speakers made within the last two years all have a date code on the speaker wire and will, of course, be replaced under warranty.

Battery Chargers:  With the exception of the Blue Ocean/CoxBox battery pack charger, battery chargers are not repairable for less than the cost of a new one. Of course, if less than Two Years old, any charger that fails to operate correctly will be replaced under warranty.
