Waypoints

Does anyone have any idea how many waypoints can be stored on a single unit? Is there even a way to find out?

Each unit is different. The manual will tell you. Look for the specs. Page.

Okay thanks. I found it the manual says 5000 man thats a lot.

HDS gen 3?? Gen 2 says 3k I think. Trust me when I say 5k will come sooner than you think. I've split mine onto cards now 2x with 1800 points still on the graph for 3 lakes and one I've only seen 2x. Happy fishing!!

You can also export way points by each lake you fish to a MicroSD card, delete them from you unit memory and and load them as you need them...just make sure you "update" each region as you add new waypoints.

Your unit will slow before you get to the 5k waypoints. Seperate lakes or waypoints by region on an SD card.

That's a good idea Tommy, thanks!

If you're a member of CAT, there is a video seminar on how to store/save/etc. I teach to save by lake. I am familiar with Lowrance, but I would think HB has something similar.

When deleting waypoints (after saving), the waypoints/trails/routes remain in memory. If you truly want to get rid of them, they must be PURGED! In other words, if you delete 1k wpts, reload for next lake, save, delete, reload for another lake, save, delete... the wpts are still in memory. If both reloads had a 1k wpts, there are 3k of wpts stored in memory. 1k deleted, 1k reloaded, 1k deleted, 1k currently loaded (3 different lakes). That equals 3k of wpts. It can easily be seen where wpts/trails, etc. will quickly overload memory. I have 1189 wpts just for Fork with 111 trails (that contain many wpts - these count too!).

To avoid this, do as previously mentioned: save by lake or region, delete, then purge. If you don't understand PURGE, then read documentation for 'Purge' in G2 or G3 documentation. It isn't in G1 documentation. The documentation states the reason for keeping deletes is to sync up units. I physically save, update the lake file on the computer, then delete and purge from both units. When I go to a specific lake, the only wpts/routes/trails on the unit are for that lake - optimum performance.

By the way, the HDS PDF documentation can be stored on the SD card and read using your unit. This helps if you're out on the water. You could also access the documentation via phone if air service is available. I prefer to read from the unit for easier eye strain and to not have to worry about air service.

thanks Jimmy,needed that info.God Bless!!

So do you have a SD card for every single lake?
