oh well Rob can settle this i guess that is what my VV did though
If the combination of LR (say 2.0 ohm) and load voltage (say 5.4 load volts) creates 15 watts or less (that example comes out around 14.5w), it will fire. If the combination of LR (say 1.5 ohm) and load voltage (say the same 5.4 load volts) exceeds 15 watts (example is getting in the 20w range), it will not. Tested with a VVPV.
I've tested resistors including 1.5, 1.7, 1.8, 2.0, 2.4, 2.5, 2.8, 3.0, and 3.2 ohm. Also, I have tested dual coil cartos and attys and they follow the same 15 watt output that you can bump up against with single coil LR stuff. Just one example is that I can fire a 1.6 ohm dual coil at 5 load volts (which does barely exceed the advertized 15w cut off), but not at 5.1 load volts.
15 watts is too high for almost every single coil and this device will certainly make just about any of them pop until you get in to 2.8, 3.0, and 3.2 ohm resistors where you can't achieve 15 watts with 5.6v
My guess is that Kabonk fired a ~2.0 ohm resistor and was not cut off as he shouldn't have been. I'll guess again that ScottM fired a 1.5 ohm resistor and found the cut off above 15w.
On a personal note: BLM and FW&P kicked me out of the area of the forest I was working in and they closed the trailhead due to avalanches and continuing avalanche danger. There should have been 45 miles of wilderness between me and a PC w/ internet at sale time. As it turned out, motel internet and my workmates laptop was a sufficient combination to get the bloodwood I was hoping for
