Gosh! I'll never get any work done today will I??
I did say "consider other expenses" because I didn't want to make a long list - I am not sure why you were loosing money on OW courses. How much were you charging per student? That sucks. The dive center owners I know of are raking it in! They don't sell much in the way of equipment.
Keep in mind that at an inland shop we teach and sell equipment. There aren't any daily boat trips or guided dives. You can't get very much for an OW class. Most shops around here use it as a loss leader to generate a market for their equipment. It's just a cost of sales. Often teaching and selling equipment can be a conflict of interest. I doubt my student buy as much equipment as the students of other shops. That's partly because of the way I teach. My classes also spend 15 hours in the pool where most shops around here do 5 or 6. I keep my classes small and get them plenty of OW bottom time. It's a good class but it's expensive. I think there is a night and day difference between my students an those from some of the other shops. You could literally pick them out UW. While very satisfying it just isn't profitable when your price must be comparable to others but the class is not.
Also consider other issues such as the fact that if you're not at a dive site you don't sell much gas so 90% of the cost od oporating a fill station must be absorbed by OW classes. BTW, try getting on as a dealer with a major equipment manufacturer. In most cases you must be a full service shop. You're forced to provide air even if the market won't justify the expense.
At the volume of gas that we sold in order to get a two year pay back on the capital expendature of the compressor (not including banks or other mixing equipment) I would have had to charge $25.tank for air. Another loss leader that really amounts to part of the cost of sales and nothing more. It's financial pressures like these that reward shops for fast cheap classes and cutting corners
MOST recreational diving IS done while people are on holiday in warm waters. I am talking on global terms here.
In my opinion, it's still better to watch the video in class if you are on holiday or not, unless the students would rather do it in their own time.
I insist that they do it on their own time because I have too much other stuff to say to spend time sitting there while they watch a video.
