Excellent hardware and software solution

I was skeptical in my search for a multi functional GPS guidance system and user friendly software for spraying and fertilizing at an affordable price. I’m not a ‘row cropper’ that needs, or uses a $5-15K system. I just need something to keep me on track so I don’t over/under spray or fertilize.

Finding this hardware and software solution has been a loaded bases home run for my non-contiguous 400 acre cow/calf operation. I have used it on my truck to spread fertilizer and on my four wheeler and tractors to spray chemicals.

The GPS guidance system tolerance is advertised as 20/30 cm (8/11 inches). I have not experienced any noticeable amount of error. It has been very accurate.

Customer service across the pond has been timely and responsive to my questions. I am looking forward to their A/B line solution for covering irregular shaped fields.

Great Application

This app and the onTrak device work really well. Easy to install and use. Very accurate tracking. I recently had a firmware update that caused a problem. I contacted Agricision via their website and had a reply within the hour. I received a telephone call and it was fixed within minutes. Great service.

Not so good

I was super pumped to try this app out in the field as I was spraying but I just can't get it to work maybe it's my phone I even did the update an I still can't get this to work won't even start the a-b line I hate it's meters an not feet so if there's any one that thinks they know what I'm doing wrong let me know

Developer Response ,

Thanks for your review - Unfortuantley the onTrak app does not do much without the Agricison onTrak GPS Device. This is clearly indicated in the app description and upon launching. Please visit our website for more information.
