I looked at the specs on both the OTAL and MR2 as well as several other on their site. They all have the smae specs. I thought there were two diodes available for each model: the daytime super power point and the magnum power point. Don't they have different intensities and diameters? Maybe I'm wrong, though. Does anyone know for certain what's up?

Look again, they do NOT have the same specs.
OTAL = Beam Diameter: 6.5 mm @ 25 meters
MR2 = Beam Diameter: 0.58 sq. cm @ 25 meters
That's the primary difference. All the civilian lasers are limited to 5 or less milliwatts, and the better ones all operate at 635nm wavelength (except for green or IR).
No visible red laser is good enough for open bright daylight, period (beyond 3 meters that is). They are only good enough for shadowed areas, overcast or dim lighting conditions, and indoors. IR, green, and military lasers are another matter.
So in general, there is no "Magnum" intensity, they are all limited in power to 5mw, however, the differences come into play as to how large the projected dot is, what shape the dot is, the wavelength (smaller wavelength is brighter in appearence to the eye) how well focused they are (some dot's get much bigger quicker as they go out in range, which disperses the light causing it to get dimmer instead of remaining concentrated). Some lasers also pulsate at different rates so you can more easily spot them or differentiate your dot from someone elses.
