My favorite thing to do!

You can also update over the internet. Here is a video on it. Your Lowrance needs to be close enough to your internet router/device. https://youtu.be/nfnIaw0JoLQ

Good Luck! Sending Positive Vibes

Find your zone, try to get into it and have faith. I try to do this: Do not dwell on partner's absence; instead, view it as an opportunity to get into your zone without distraction. Your decisions are now simplified and are just yours, not a coordination. You can break down your tournament into manageable chunks and focus on only the next fish, one spot, and one hour at a time. Try to make sure your internal dialogue is positive? For example, if you say, "I am at a disadvantage fishing alone," change that to, "I can adapt more quickly without coordinating decisions." Keep your energy up, hydrate, eat, and maintain focus. As BLat says, know what you are good at and your confidence baits, then find those fish. It is essential to have faith and visualize yourself handling the tournament well and managing the situations effectively. 

The Onboard maps are good. The HDS Pro also does overlay as you drive to update the maps. 

I am eager for 50 degrees in the morning and 70 degrees in the afternoon. I have a few more weeks or months to wait for that. This is the time of year when I start to feel stir-crazy.
