I would personally go with the geodnet/wingbits dual miner https://heliumdeploy.com/products/wingbits-mgw310?srsltid=AfmBOoq1lT9Bx5W7_aBvzN5mDj7aWCB5tGfDb_Dkh9WJe1J5xxhNSLLj

Geodnet 100 percent

Both Hivemapper and Rovr TX don’t have the earning potential compared to the other two.

The nice thing about Geodnet is it’s easy to install, you know exactly how much you will earn, and you can just forget about it. If you have an install location that meets the sky view requirements and is the first in its hex then this is a good option.,

That being said, the Helium wifi hotspots have the potential to (greatly) out-earn the Geodet station, but it’s all dependent on finding a location with the foot traffic AND getting that location to allow you to install. Also, and I might be wrong here, it’s difficult to get carrier offload selected for the outdoor hotspots; indoor units seem to have much greater success. But this supposedly is changing with their future POC reward change where it will be based on connections, which in theory should mean any station getting enough connections would be selected for carrier offload.

Three thoughts:

1. Do you, a friend, or a family member have a location with decent internet service that you could cover with a PoC multiplier of 0.7+? Get a HM Outdoor. This is an even bigger no-brainer for anywhere that has good footfall like bars & resturants, parks, human-scale development with sidewalks and small shops, etc. since you’ll get $0.50/GB for offloaded data on top of a few bucks a day just with the current proof of coverage rules.

2. Do you drive more than, say, 10 hours a week with at least a majority of that being varied and not just commuting the same route? If you’re at 10-20 hours a week then start stacking drive-to-earn stuff including 375go from 375.ai (free), the NATIX app (free) if you have a spare cell to mount on your windshield, then the TarantulaX which currently has a better ROI than Hivemapper. If you’re driving 20+ hours a week and it’s not all the same roads and not mostly highly mapped highways then I’d get the Hivemapper, too. TarantulaX really needs a separate phone mounted and aimed out the front of your windshield btw.

Warning about the TarantulaX: Their product design is flawed, and the customer support I experienced is bad. I bought two of these thinking I could have my wife use it but she didn’t want to mess with it (I don’t blame her) so I used them depending on which car I was in. I have now broken BOTH of these stupid things because their USB design is atrocious and almost impossible not to bump and break at some point in a car. They’re giving me the run-around on getting a repair or replacement so just know what you might be in for.

3. I’d only do GEODNET if you can afford a base station and are in a hex that’ll let you earn the full 24 tokens a day (soon to be 12 a day at halving in a few weeks) I’d strongly consider that. Read up on tree coveage being an issue. And the product you mentioned I assume is their accuracy verifier portable degice and if so that’s more a cool gadget than an investment at the moment given the limited opportunities to earn from it they have right now.

Personally for me the best project in terms of overall potential is still Helium. But I have Geodnet as close #2 @cryptoskater55
