If you have your gear serviced annually ( Scubapro's recommendation ), then you get free parts. Let's use a Mk 25 first stage and S600 2nd stage ( one regulator system ) as an example. We charge $25/stage for labor = $50 per system. Over a two year period your cost is $100. Parts are Free!I suspect that if you only serviced the regs when they needed service, that you would more than save the cost of the bag of parts. I own quite a bit of SCUBAPro stuff and my service interval is "when it leaks or misbehaves."
flots.
If you service your gear every other year, your cost are labor $50 plus parts.
Mk25 service kit = $23, S600 service kit = $20. ( Price may vary depending on Scubapro dealer or black market )
Total cost = $93
Is it worth saving $7 not to have your gear serviced to the manufacture's specifications?
Do you wait to change the oil in you vehicle til it misbehaves?
Hopefully, you aren't doing Tec diving with gear that is destine to fail!
We require that our students use gear that has been serviced. It is mandatory that your gear is within it's service interval and bench checked before joining one of our trips.
