Understandably, most of the comparisons here are to Fire Axe, as the equivalent of it, and looking at it like that, it comes up a little short. Another interesting comparison would be the Fingerprint Kit. A card that is 4 resources for 3 investigations at +1 that potentially net you six clues. Looking at the compass as a comparable card, it's 1 cheaper to get into play, but making each test at the same bonus will be more expensive, ending up at 6 for the card and three +1 investigations. Of course, it doesn't run out of charges, and you don't have to spend those resources, and can even spend more. So long as you can take advantage of that, using it more than three times, or synergise it with other cards, it gets more value. So if you think Fingerprint Kit is good, it can be better if you can keep it in play and don't mind staying low on resources.
Obviously, this comparison is faulty, too - a seeker tool is always going to be different to a survivor tool. Not that many Survivors have the to really make use of this. Wendy Adams and Calvin Wright are probably the best stat-wise, with Preston Fairmont able to make it up with resource shenanigans. But even the other survivors can make up for their lower stats with survivor tools like Dark Horse or Lucky!
Cross-class, Minh Thi Phan, Rex Murphy and Finn Edwards benefit a lot from this card, though Rex can simply run a Fingerprint Kit build, so he has to build towards it to make it worthwhile. Minh can take as many Survivor cards as she likes, so I think it works best in her. She can stay low-resource in a Dark Horse build without it really hurting her, and all but guarantee the two clues a turn with committed skills and/or Lucky! or Live and Learn in hand. Alternatively, Rex can overcommit on compass tests, pick up three clues with one action and use the rest for things you usually struggle to find time for as a seeker.
I think it's a good card overall, but limited more than a little by its class. If we ever get a Survivor 5/Seeker 2 it might find a place where it really shines.
