The most economical global GPS Tracking solution.

YB3i uses the Iridium Satellite network. Specifically, it uses an Iridium service called 'Short Burst Data' (SBD). At the heart of YB3i is an Iridium 9602 modem.

The YB3i can be mounted in a variety of ways. The simplest way is to purchase our optional Rail Mount (available in the shop), which allows the unit to be easily mounted to a rail or pole. The unit can also be stuck down flat, in ceiling voids for example, using high-strength velcro on the flat base. Lastly, it has a set of 4 recessed M5 bolt holes on the base. You can use these to secure the unit using your own mounting solution, by bolting through a plate or hull.

Ensure the unit is powered, and any connections in the circuit are good.

Hardware reset the device by swiping the reset magnet all the way around the outside edge of the unit. If you have misplaced the supplied magnet any other magnet will be suitable. The unit will beep after about 10 seconds, and will then be reset.

If neither of the above work, then please get in touch with the support team.

Intermittent green flash – running on external power

Intermittent red flash – running on battery

Red/Green alternating – booting up or updating firmware

Off – in shipping mode, stealth mode, or the battery has run out and there is no external power.

Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. The device battery is not user-replaceable; it can only be replaced by your device service provider.

Having said this, the battery in the device should maintain its ability to charge to at least 90% of capacity through 1000 charge cycles. This means that if you charged the unit every day (unlikely) the battery would need to be replaced every 3 years. If you charged the device once a week, it would need the battery replacing once every 10 years. However, you do not need to worry about this issue if you have the unit connected to the yacht’s batteries 100% of the time. With a power draw of only 350 milliamps, your house batteries will only go flat if left unattended for a very long time.

Your unit is equipped with both Iridium & GPS antennas located on the top ‘domed’ part of your casing. For the best results, it is important to be mindful of the orientation of your device when in use.

To ensure a good satellite signal, the antenna should be clear of obstructions and have a clear view of the sky. We recommend installing on the pushpit or similar location, not on the mast.

The device is designed to attach to your yachts batteries 100% of the time, via the cable. However, it does have an internal rechargeable battery which is used should the unit lose power.

The YB3i comes wired with 2.9 meters of cable from the factory. You may need to extend this to get it to your boat's distribution board. You should extend it with the same gauge cable and type. Ideally 1.5mm2 (16AWG) twin core with a sheath.

Each wire core (Positive and Negative) should have 2 layers of insulation like the cable it comes with. Simply wire the positive and negative cores of the cable into a spare circuit in your distribution board.

This new feed should be fitted with a 2A fuse near the power source to protect the cable in the case of a short circuit of the cable. The unit will run on any DC voltage between 9v and 32v. On average the unit will draw about 350 milliamps under normal operation. Wiring should be carried out as per the following:

Standard 2-Wire

Brown (or Red): Live (9-32v DC)

White (or Black): Neutral (0v DC)
