I have been using a Lowrance HDS Gen 3 unit to collect my data. My use of this software is less about fishing and more about commercial applications associated with lake dredging projects. My company comes in and assesses channels and lakes in the USA for potential sediment removal. I have found this software to be exceptional in helping to visualize to the client and help assess projected volumes of muck/sediment to be removed. Please let me know if there is anything I can do to help keep this product development going. Not that I want to pay a monthly subscription, but it seems like a lot of of the software is going that direction and would generate needed funds to keep updates happening. Its really amazing software and not much out there to compare to. Anyway, my question is this. My Gen 3 unit has been a little glitchy lately. Sometimes turns off or freezes up during a project which I can't have. I've been looking at upgrading to the Lowrance HDS Live or more recently release HDS Pro. I assume they collect data in the .SL3 format, so should be compatible with Reefmaster, but I wasn't sure if that is the case and was hoping someone with first hand knowledge could let me know if those units are compatible before I make the purchase. Thanks for all you do. Keep it up.

I use an HDS Live with Reefmaster and it works fine. Cannot comment to the new Pro.

I think the only real problem with the 'Pro' currently (at least that I know of) is that is doesn't have AT5 support. Which is fine if all you are doing is collecting data and making map to show a client, but if you want to actually use your map in your unit, you won't be able to do that. I hope this changes in the future but it's just fingers crossed sort of thing. I'm using a Carbon unit and it's been great. Granted im saving files to card and not connecting to a computer.

HDS Pro units do read AT5 Maps. No problem.

I definitely cannot get a Lowrance HDS Pro to display an AT5 map. My older HDS live 9 would display it. Same card, same map.

I submitted a ticket to Lowrance by the website, which seems to be the only way to get ahold of support. Just hitting 22 business days without a response. The ability to use reefmaster on lowrance was the sole reason I bought the unit.

I'll take any suggestions or ideas. Very frustrating.

I’d like to hear what the answer is. Thinking about purchasing a new HDS Pro myself

Hi, I am using Reefmaster/IMC maps (AT5) on my Lowrance HDS Pro units without any problem.
If you want me to test your AT5 map on my HDS Pro units, I can do so. Just let me know. I would be glad to help you out.

Thanks
