It's a pretty neat system! I purchased the OffCourse this past summer. Erik was quick to respond to my questions prior to and after the purchase. I received the unit within a week of the purchase, quicker than I expected. After initial setup noticed one of the markers had a slow CO2 leak, reached out to Erik who quickly helped me diagnose the issue and sent me a new marker without hesitation. Since receiving the new marker, we have had a blast with this system on the Pittsburgh river system, a fresh change and new challenge to our normal free ski routine. The balls are very easy to see when they hit the surface of the water, Erik has done a great job masterfully designing this unique system. Like any ski boat, weight distribution is critical to wake performance behind the boat. No different with this system, keeping the boat or markers as level as possible to ensure the balls are hitting equal distance on either side of the hull. There are adjustments to either marker if you need to slightly raise or lower the ball approach angle, but if for example you change out drivers and their weight is different, it can throw the system off slightly which is a bit frustrating. If Erik and team and can discover a gyro like cost effective option to ensure the markers always stay level and eliminate the detail of weight distribution (even while the boat is under power) then this would be a 5/5 system. But until then, if you at your mates have a few extra dollars, go in together on this purchase, its certain to put a smile on everyone's face and if you're like us who always free ski, we can now share the feeling of having our own private ski course wherever we want!

Just wanted to give some input from Sweden on OffCourse Just wanted to give some input from Sweden since my wife and I now have skied with OffCourse (OC in the rest of the text) mounted on our Malibu Response 340hp from 2005 equipped with PP Stargazer and Z-box. We have the boat based in the Stockholm archipelago with no possiblity to put in a course at our location close to our house. When I first heard of OC a couple of years ago I immediately thought that it would be perfect for archipelago course like skiing after our own boat instead of only doing free skiing. We are both fixed buoy course skiers also and members of a club with a course on a lake. My wife skies into 32mph and I ski into 32off at 34mph (soon old enough for 32mph though..). I have to say that OC lived up to all my high expectations. The best things are actually the new Z-magazines that holds 24 balls each, matching the life of the CO2 cartridge so you reload everyting at the same time. The Z magazines allows you to do 48 turns in a row if you have the space and the stamina, absolutely wonderful! You do need to get the course width right and you do need to learn how to time the start with the boat crew so you get the zero ball were you want it, but that is easily solved after a couple of tries. I really think that this is a great training aid if you don't have access to a normal course where you ski, well done Erik Berghiller!!!

it a little difficult to calibrate in… it a little difficult to calibrate in the water and would be great to have a colored splash so its easier to see

Great product Great product, fantastic service.

Game changer This is a great product that will improve my skiing! I don’t always have access to a course so OffCourse will be a great tool. The build quality is top notch and customer service from Erik and the team is excellent. Well done.
