I pay about $400 a pop. They need to be certified and that is how you cna make sure they are not goin to screw you. I use the same guy at a local dive shop. or you could take the course and do it yourself. It's a weekend course I think. Then you can be the one making the money.
Get a group together and attend Singapore's KB Associates for a maintenance course that is certified by DSI Kirby Morgan. They have the full range of hats including the very lates KM77.
anybody have any info on the KMSDI course in Canada? Have been wanting to do one for a while but trying not to pay a fortune for a flight
