Now that I have a month or so using this pin pointer, I feel I can give it an honest review. For a run down on all the technical information for the Makro, see my initial review here.
Diving right into it...
Pros: Construction and engineering are top notch and I predict it will hold up for all the serious metal detectorist out there. I'm very hard on my pin pointers and I feel this unit will hold up. Using this pin pointer for over a month or (7) hunts, ranging from a few hours to all day, I changed the battery once (last hunt) due to battery running down. It still worked but noticed a loss in distance to target. Audio signal is loud enough to hear with your head phones on. Vibrating mode is strong enough to use verses the audio mode. I prefer the vibrating mode.
Cons: Really the only big con to this unit is getting it to turn off. You press and hold the GREEN button until you hear the audible beeping. The unit is then off. To me, the unit takes to longer to turn off as several times I put the unit it back in the holster and it was still on. Other pin pointers you just push the off button and release . While hunting in a target rich environment, an efficient recovery is needed. Holding the off button until it beeps is not efficient. Lastly, there is no place to tie a lanyard. Using a lanyard in and around water is a must. Check out Detecting Dodads for a nice after market lanyard for this unit.
Other observations...The buttons are in the wrong place...located in the battery screw top end, it was a bit awkward at first. I did get use to it the first day so this is not really a con. The GREEN button turns it on as well as off. The RED button changes the modes and does not turn the unit off. I knew this but still seemed to get caught up in the old GREEN MEANS GO and RED MEANS STOP mental quagmire for a few outings. The speaker is located in this area as well and you can muffle it while using the pin pointer.
I did not get a chance to use this unit while hunting in the water because I'm not getting in the water in January / February in Virginia. I did submerge the unit in my kitchen sink for over an hour with no problems. I do have several water hunts planned for early spring and will update this post after those hunts.
Final thoughts: This unit is a nice pin pointer no question. It is a step above the Garrett (non waterproof) and the Minelab in my opinion. It will take a few outings to get use to the location of the buttons and I would like to see a quicker off cycle.
