Absolutely the BEST computer service and sales shop in Collingwood! My desktop died and Pat was able to save all my data and get me set up with a new computer at an incredible price - all within a couple of hours. I definitely recommend Mariner for any of your computer needs!

If you're a senior, this is the place to buy or have your computer serviced. When you pick up your computer it's turned on and he goes through everything with you, setting up shortcuts and answering all your questions. He sets you up for success and he is easy to deal with. He's definitely a people person. Its nice to finally have someone in Collingwood who operates this way.

Thanks for your help. My HDMI port on my laptop is not functioning and you gave me the best advice. Buy an HDMI to USB cable. Too expensive to replace the HDMI port. Thank you. Thank you!!!!

If you don't know where the best computer service is in the Georgian Bay area I'm here to tell you that its Pat at Mariner Computers. I run a big business on my computer and I have dealt with people who said they were the best computer people around only to be disappointed time and again. Pat is the real deal. He plans out a strategy with you and he executes as a professional. Thank God for Pat.

He did a wonderful job at cleaning up my laptop and organizing everything for me. Replaced my battery too. Then he brought me in and sat me down and gave me some much needed pointers and instruction. This store is a great resource for our community.

Pat provides excellent customer service and is very knowledgeable. He did everything in his power to ensure that the laptop that I purchased from him was working correctly. I highly recommend him to anyone looking for honest, professional computer support. Thank You!

My experience and satisfaction with Marine Computer Service is absolutely a five star! Pat fixed the problem, took the time to set everything up, and walked me through how to use the set up efficiently. Pat also followed up the next day to update the drivers on my printer, and sync my photos on iCloud to my pc. I could not have done this without him! He is truly a wealth of information and knowledge! I highly recommend anyone needing technological assistance to reach out to him! You won't be disappointed! I will most certainly use him again!

Pat is fantastic, he helped me with my PC crashing problems saved me $140 By explaining to me the next steps, I should take instead of him doing it himself and charging me. I Guarantee no computer place would do that. He gave me this information all with a free diagnostic, it’s much appreciated and thank you for giving me a path moving forward!
