Thanks for posting, good question.
Hollis offers FREE routine annual maintenance (parts) for as long as you own your Oceanic Product and maintain the terms specified below:
1. Buyer must register his product
2. All products must be inspected and/or serviced annually by an authorized Hollis Service Technician.
(Must show proof of authorized service within 12 months)
This program applies to all Hollis Regulators, Buoyancy Compensators, Dive Computers, and Analog Gauges purchased and serviced through an Authorized Dealer. By registering your product you are automatically enrolled in the program. There is no additional charge for this program.
This program allows for parts to be provided at no charge for as long as the owner maintains the terms specified below. Individual dealer participation in this program is voluntary. A dealer is only obligated to honor service agreements that they have issued. Any Authorized Hollis Dealer may, at their option, honor a service agreement issued by another dealer.
All labor fees incurred in overhaul service are the responsibility of the owner of the product serviced. This includes, but is not limited to inspection, calibration, battery change, overhaul or other services performed.
Thanks!
