Gobbler, what DoubleUp said about the Spark is a good idea. I did purchase a cheap laser and it would work well at close range. You would have to mount the Spark to your rifle or a helmet, but from what I have read, mounting to a helmet is tedious for the Spark. Armasight does have a rifle mount for it but it is not cheap at over $100. I tried to fashion my own mount and it worked, just crude and put the Spark too high to my liking.
Also, you have to be careful with the type of laser you get since some of them have a beam that is too bright and large. The small I tried one initially and it was way too big and bright to be of any use, but the smaller one I got works fine with the Spark. The Spark has short eye relief too.
One thing about the Spark is that on a bright night like we have had lately, I didn't need an illuminator to see. I could see well enough while waiting for hogs that I only needed the illuminator to look into the shadows. Of course, on dark nights you definitley need an illuminator.
Rick, I purchased a small solar panel not long ago in hopes of keeping my Sportsman's Guide battery pack fully charged. I leave the battery pack at the cabin but it runs down over time and I have to take it home to recharge it. I wired up the solar panel (which is a trickle charge type) to a charge controller and can't get it to work. Either there is something wrong with the controller, or the battery just doesn't put out enough power to make it work, not sure.
My question is, will a trickle charge solar panel hurt a battery that is left unused for lengthy periods of time?
