Yup

It depends alot on your skill level and what your build is focused on.  I'd recommend checking out the strategy forum as there are some good builds there (these include what items to buy, what skills to buy, etc).  Here's one:  http://forums.demigodthegame.com/371355

Reg is a long range demigod, and i do play as him often. AS i have found early game, reg needs a lot of mana to feed him, but he is also quite fragile, so i get blood of the falled as his favor early game. reg devours mana super fast, but he is also easily killed. Crit hit weapons are great for him too. just ask me what kinda build ur giong for.

Tracking device is a pretty useful ability. You'll usually get a couple more kills if you have it, and it will force more trips back to the citadel on lower-health demis as they know they'll get whittled down if they stay out. LE is about the only demi that can get rid of the tracking device easily. I have a build around here somewhere that allows for a lot of lane and long range damage, but forgoes scope. I honestly have never needed scope. Soloing towers is ok, but the ability to push to reach the towers is more important.

Tracking device is perfect for "molest" reg. He can see his targets at all times, and just keep sniping them, keeping them up on damage. And, of course they will try and stop you, but all you must do is make a mine trap. Maim + Tracking can be used defensive, so you can save allies a little by slowing and hurting incoming enemies. But really, I can tell you nearly any reg play style you are looking for. You looking for long range kills? Creep farming? I can tell you how to do it.

I use the tracking device primarily to finish off DGs. If they have to retreat from combat, I can hit them at least once, and often twice, before they make it to a crystal. Sometimes minions heal them, but often they are oom and without minions, or their minions are too far away.

So if I'm on one side of, say, cataract (which seems to be the only map in the game :[ ), while helping in my lane I'll watch to see if my ally on the other side of the map is engaging. If so, I'll snipe his target to soften it and plant a tracking device. I'll snipe again and again while he's fighting until the enemy runs, and I'll keep sniping until he's dead or reaches the crystal (or I'm oom, which is a bit less often now that I carry mana pots).

No, you need the tracking device skill to have a tracking device. Once you have the skill, both regular bolts and snipe bolts will implant it.

Random Fact: Universal gadgets can be used to fix towers. This was just pointed out to me...

IMO, you'll do better using mark (and eventually shrap mines) for slowing than putting a point in maim. Maim doesn't really last long enough to guarantee that you'll get more than 2 snipes in on a running opponent. Mark, however, can and often does save you when you are trying to get away from a melee.

Thanks. I have added the tracking device skill. You guys have helped me a ton. Thanks again. I will try not to embarass myself out there.
