Before Your Trip
With average dive depths between 25 - 35 metres, diving in Truk Lagoon is suitable for experienced recreational divers and technical divers. However, it is generally considered to be unsuitable for entry level divers. Additionally, there are some wrecks which are significantly deeper than recreational limits, which are therefore only accessible to technical divers.
The majority of wrecks in Truk Lagoon are within recreational, no-decompression dive limits at depths of between 18 metres and 40 metres. Others, which are only suitable for technical divers at depths of between 40 metres - 64 metres.
Recreational divers are required to have PADI Advanced Open Water certification, or equivalent, with a minimum of 50 logged dives, and preferably Deep Diver Speciality (40 metres).
Technical and rebreather divers are required to have the relevant certification and experience for the depths and type of diving which they are intending to do.
Guests who do not meet the minimum requirements, or who the crew feel have insufficient experience in certain conditions, may be denied participation in some or all dives.
There are no facilities for repairing or servicing diving equipment in Truk Lagoon. Whilst Pacific Master carries a limited amount of tools and common spares for making repairs in the field, divers should ensure they bring everything they need to be self-sufficient. This is especially true for rebreather divers as we do not carry any special tools or parts such as oxygen cells or batteries for rebreathers.
Technical Divers need to have the following:
- Two methods of buoyancy - All divers carrying out technical dives from Truk Master need a second means of buoyancy.
This can be achieved by using a wing with a redundant bladder, drysuit or lift bag with a minimum of 20kg/ 45lb of positive lift.
- Dive Computer - Multi-gas dive computer capable of switching between a minimum of 2 gasses, ideally more.
- Backup Computer or depth/bottom timer.
- 2 Surface Marker Buoys (SMB): One red or orange SMB and one yellow SMB with a slate or wet notes attached for emergency use.
- 2 Reels or Spools: One with a minimum 15m of line and one with a minimum of 60m of line.
- Dive Slate or Wet Notes: Additional dive slate in addition to the slate used with the emergency surface marker buoy or a set of wet notes.
- Minimum of two dive torches (ideally three) for any guests planning on doing any wreck penetration.
Cylinders, Gases and Sofnolime supplies are limited and subject to availability. All requirements MUST be requested in well in advance by completing the Technical Equipment and Gases Requests Form and returning it to our reservations team as early as possible.
The remoteness of the destination means we have to order supplies from outside of the Federated States of Micronesia making it difficult to accommodate any requests without at least 3 months notice.
All divers are required to sign the relevant liability waivers for the activities in which they will be participating during their liveaboard trip.
In addition to our standard Boat & Travel Liability Release, medical statement, and standard safe diving practices releases, technical and rebreather divers are required to complete the Technical Diver Liability Release.
As rebreathers use variable gas mixes, all rebreather divers need to sign the technical diving waiver, even if they are diving recreational profiles.

During Your Trip
We are unable to offer any diving courses on our Truk Lagoon itineraries.
Daily diving is planned in such a way that both tec-wreck divers and recreational divers can explore the wrecks at leisure according to their certification and experience level.
We usually dive straight from the main vessel directly on to the wreck site but we may also offer guests the possibility of an alternative dive site from the tender.
We do not normally limit dive times for technical divers (unless we need to move the boat) but meal times are fixed.
Technical divers are responsible for planning their own dives, including necessary decompression stops and are required to submit their dive plan to the Cruise Director before each dive.
Pacific Master is equipped with booster pumps for supporting rebreather divers. 2L and 3L CCR cylinder sets, as well as stage / bailout cylinders, are also available to rent.
