Divetech will fill customer provided cylinders with enriched air mixes from 41% up to pure oxygen only after a Divetech technician has oxygen cleaned and inspected the cylinder prior to filling.

Scooter Rentals

Underwater Diver Propulsion Vehicles are also known as DPV's or scooters. Scooters that Divetech rent are very fun, but come with additional risk. Improper use of a scooter can lead to increased risk of decompression injury or sickness. 

Furthermore, underwater scooters are very expensive. Improper use of a scooter, or failure to follow Divetech's rules on their use can result in damage to the scooter. 


Upon renting a scooter with Divetech, the participants will be asked to sign a scooter waiver. You will be responsible for damage or loss to the scooter should this occur as the result of your negligence or failure to follow the rules. The replacement value of Divetech's scooters are upwards of $3,000 USD each. Repair labor is billed at $100 USD per hour, plus parts. 

Technical and Rebreather Diving Policies

All divers who wish to engage in planned decompression diving, or diving using breathing gases other than air, must be properly certified to do so. All dives conducted, including maximum depth, decompression time, and breathing gasses, must be within the limits of the diver's certification. 

Divers using rebreathers must be certified to dive said rebreather. Rebreather divers must remain within the maximum depth limits of their rebreather certification. Sorry, our insurance does not allow us to accept open-circuit trimix certifications in lieu of a rebreather trimix certification. 

Rebreather divers who wish to dive deeper than 200 feet / 60 meters must carry AL80 bailout bottles. AL40's are not allowed for diving deeper than 200 feet / 60 meters. 

All certifications must be presented to Divetech staff prior to diving, and must be from a recognized training agency.

Recreational Diving Policies

All divers must be certified for the diving they wish to conduct. Proof of certification must be presented to Divetech upon initial check in. The scan be via a c-card, or digitally. For certain training agencies we may be able to verify your training certification online. However if we cannot verify your certification, you will not be able to dive. 

Recreational boat dives have a maximum time limit of 60 minutes surface-to-surface. Decompression diving is not allowed on recreational dive charters, despite the diver's level of certification. Divers who inadvertently exceed the no-decompression limits, will not be allowed to dive the remainder of the day. 

Recreational divers must surface with no less than 500 PSI / 40 BAR of breathing gas in their cylinder. 

Rebreather divers, and divers using twinsets/doubles are allowed on recreational boats, however their dive profiles must be 60 minutes or less, they may not exceed 130 feet / 40m of depth, and they must remain in no-decompression dive status. For those who wish to dive outside of these limits, please see our technical diving polices. 

Outside instructors

Outside instructors are more than willing to conduct training classes at Divetech facilities, boats and using our equipment. Instructors must have Divetech listed on their liability insurance and provide a copy to us prior to conducting any training class. 

Training class policies

All students must complete a medical waiver prior to enrolling in any training class. The medical waiver is available prior to class upon request. If the student answers "yes" to any question on the medical waiver, training may not commence until the instructor receives a note from a physician clearing them to dive. If the student does not have a physician note, they may not commence training, and forfeit any funds paid or owed for the first day of training. 

All training classes have set standards and curricula that the instructors must adhere to. Classes are priced on a fixed schedule and set amount of training days. The schedule allows for a reasonable progression and ample time for students to complete the class requirements. If a student is unable to complete the required standards of a training class, the student will be required to attend additional days of training at additional expense. 

Students who do not complete the class requirement will not be issued a certification card, and no refund will be given for the cost of the training class.

Guided Technical and Rebreather Dives

Technical and rebreather divers who do not have a dive buddy may hire one of our technical or rebreather dive guides to accompany them. The following limitations apply: 

  • Maximum depth limit for guided dives is 330 feet / 100 meters

  • Maximum total runtime is 3 hours

  • A dive planning session must take place between the diver(s) and the dive guide prior to all guided dives involving planned decompression.
