The compact size and tight tolerances of the Suunto D4i dive computer mean that specialist tools and equipment are needed to change the battery and properly test it before use. Our technicians are fully trained and experienced to carry these out in our store.

The turnaround for the Suunto D4i Battery Replacement is 5-7 days. We also offer a two-hour express service if you are really pushed for time - please note this is subject to availability so check with us before proceeding.

When was the last time you checked the condition of your watch strap? The simple strap is all that holds the expensive dive computer on your wrist it is really important that the strap is in good condition. Get us to fit a new strap whilst we're stripping it down to change the battery and pressure test the unit. Why not get us to fit a new display shield at the same time too.

Please note that due to the deterioration of batteries and o-rings we can only use our own stocks of genuine kits to ensure you get the maximum life out of your battery and optimal seal integrity. Our kits are carefully monitored and rotated to ensure our stock is always fresh.

There are various options with regard to getting your dive equipment to and from us. We can accept drop-offs or deliveries to the store, but we can also arrange the collection of your equipment. Similarly, for return of equipment it can be picked up once completed, or we can arrange for the equipment to be delivered to you.

Please note that servicing products are excluded from the free UK delivery offer as we use a suitably insured next business day courier service to ensure your equipment is protected against damage or loss.
