can you change batteries, can you point at objects or do you need a screen and how far does the lazor travel

The batteries last a while, but yes, they can be changed... See page 6 of the manual here: http://www.nextleveltraining.com/sites/default/files/resources/SIRT%20110%20Pro%20Trainer%20Manual.pdf There are 2 Lasers - one red which comes on when you put light pressure on the trigger (prep), and one green, which displays above the red when you squeeze the trigger (break). You don't need a special screen, you can display on any surface. I don't know what the actual distance is, but I've used this on a 50' range with no difficulties. Hope this helps...

It has adjuster on it. If your battery is big you can adjust it to your battery size.

Yes, you can use batteries. That's all I've ever used. They last pretty long. When the battery is getting low, there is a tendency for the red flashing light to stay on. This device actually works well

Yes, when you are "ranging" (holding down the range button) you get continuous readings of whatever the laser is bouncing off of, and you can move the range-finder around while you are doing that. The pin distance will come up as you wave back and forth across it. So you don't need to be very steady.

It needs batteries for the laser. If you just want to use the level adjustments then that requires no power

No, it uses batteries. You will, however, not be happy with the display.Mike

yes, you can. It is removable, so you can insert and change batteries, also you can install it on any corner if you want, or just leave it off.

You can get to the batteries to change them. The back piece sticks- the front piece which houses the batteries is removable and can easily be put back.

This has range finding capabilities using the MIL scale reticle. It is NOT a laser range finder, but if you are willing to do a bit of math and practice, it works well. Benefit is that it does not require batteries. An accessory that helps with using MIL scale ranging is the Mil dot master.

I don't know how you want to use it for boating navigation. It has a tracking feature. You can manually input coordinates and go to that location. It has many features. It uses 2 - AA batteries.

Easy to change combo, yes. Battery life sucks though. Change the batteries at least once a month. Also the finish on the handle wore off in about the first month.

Just load and connect batteries. Some details like masts come in a little pack and simply are put in place. Batteries in the ship should be removed and loaded after use..

No. I think there might be software available that you can use to tie the telescope to a computer, but it isn't necessary to use a computer with it (I don't use one with it). It is a good idea to have your GPS or latitude/longitude location for where you will be using it at, as that is the best way to get it set up so it knows where it is at so the internal computer (that is part of the drive system) can figure out where it is pointing and then find things (if you want to use that feature). As an example, since I live in a small but heavily "light polluted" city, I generally don't use it in my own back yard, but instead take it out camping or some evenings will drive out into the countryside (to state land that is about 15 minutes away) and use a GPS app on my smart phone to find my location to enter it into the telescopes system, so that I can use that feature to locate things that are worth seeing and to use the "tracking" system that will move the telescope with the sky so that what you are looking at doesn't drift out of sight as the sky rotates. I do recommend purchasing good rechargable batteries for the telescope though, as it does use a modest amount of energy (the rechargeables I use will last a little over an hour and I keep an extra set of them charged with the telescope so I can change them out), otherwise you will be using 8 alkaline batteries every couple of hours of use (whereas the rechargeables, while about 2-3 times the price initially will be usable hundreds of times before needing to be replaced). There is also a large battery pack option (can't recall what it is called now) that is available for the telescope which I would recommend if you plan to use it for longer periods of time (I play to buy one at some point, but just haven't made the purchase yet).

You can, but difficult at higher magnification, I use my all the time, I replaced the the battery operated led with a 12 led from radioshack, connected to the power source, because I forget to turn it off! Lol,

make sure you pull out the tab that separates the batteries from the metal. The ''pull tab'' is on most toys and appliances that DO include batteries. I bought this a long time ago and I use it for hunting. BTW- it is more of a ''Widespread'' than ''Beam'' or ''spotlight'' as most people say....but I use it to leave the shooting house, not shine on the deer because it would not put enough light on it. If you are looking for a really good hand held light that zooms in get one with a convex lens.

I ended up returning the thing because it wasn't compatable with our system. On the other hand, it seemed really useful and convenient. I forgot the distance on it, but I'm sure you can look it up. There's one power button and a smooth adjuster control. Needs batteries - if I remember correctly, it came with two triple A batteries. I hope this is of some use. Also very light weight.

Only batteries and maybe soil. But only if you want to change plants or spread them out a little.
